INTRODUCTION TO THE IP250D
1 Introduction to the Teledex IP250D VoIP Network Terminal
The Teledex IP250D VoIP network terminal is very similar to a modern business desk
telephone. Instead of using telephone lines, it connects to the office network in the same
manner as computers and printers do. The acronym VoIP means Voice over Internet
Protocol. The voice and control signals to and from the IP250D are entirely digital data
that is transmitted over the office data network, rather than phone lines.
FIGURE 1.1 – THE IP250D KEYSET
1.1 THE IP250D WORKS LIKE A TELEPHONE
The IP250D functions in a manner very similar to a modern office telephone that is
connected to a PABX (private automatic branch exchange.) In this user’s guide, the
IP250D VoIP network terminal will sometimes be referred to as a “phone.”

INSTALLING THE IP250D
1.2 TWO LINES
The IP250D can handle one or two calls simultaneously, much like a standard “two-line”
analog or digital telephone. However, there is only one line (or cable) connecting the
IP250D to the network.
1.3 THE NETWORK
Instead of telephone lines, the IP250D connects to other IP phones via an Ethernet network.
1.4 THE CALL CONTROL SERVER
A specialized network server, called a “SIP server” for SIP IP phones, or a “Call Agent”
for MGCP phones, controls all of the IP250D terminals, and other types of VoIP
terminals that are connected to the network.
1.5 THE NETWORK OR SYSTEM ADMINISTRATOR
The IP250D requires configuration in order to work properly on the network. This task
is performed by a technical specialist referred to as a network or system administrator.
The network administrator will perform the configuration steps from a control station.
2 Installing the IP250D
Installing the IP250D at an office desk or workstation is as simple as installing a
conventional office telephone.
2.1 A MATTER OF SAFETY
WARNINGS mean danger to persons and possibly, damage to equipment. Whenever you
see this symbol, be careful to study the steps that you will perform, and be sure that you

INSTALLING THE IP250D
2.2 UNPACKING THE IP250D
The IP250D VoIP network terminal package contains several components:
• The main base unit, sometimes referred to as the keyset
• A handset for use during conversations
• A desk/wall mount bracket, to support the keyset at a convenient angle on
the desk, or for mounting the phone on a vertical surface, such as a wall
• A network patch cable for connecting the keyset to the network
• A handset coil cord, to connect the handset to the keyset
• Package may also contain an optional power supply (if necessary)
2.3 CONNECTING THE HANDSET
Plug one end of the coil cord into the RJ-10 receptacle on the handset and the other end
into the receptacle on the left front side of the keyset. Place the handset into the cradle of
the keyset.
2.4 CONNECTING THE IP250D TO THE NETWORK
Warning! Risk of electrical shock! Dangerous voltages may be present on the terminals of
the network patch cable after it is plugged into the network wall jack. Connect the patch
cable to the keyset base first, then to the network wall jack.
WARNING
Plug one end of the network patch cable into the RJ-45 receptacle labeled 10/100 SW on
the bottom of the IP250D keyset. Connect the other end of the cable to the network wall
jack (receptacle) designated by the network administrator.
Caution: Do not connect a telephone cord to the network RJ-45 jack. A standard RJ-11
telephone cord connector can fit into the RJ-45 jack, however there is risk of damaging the
equipment if this is done.
Note: The IP250D will not function until it has been configured and activated by the
network administrator.
ꢀ
2.5 CONNECTING A PC TO THE IP250D
If the office or cubicle space has only one active network receptacle, and another network
device such as a PC must share the same space, the PC should be disconnected from
the wall jack and reconnected to the RJ-45 receptacle on the bottom of the IP250D that
is labeled 10/100 PC.

INSTALLING THE IP250D
Caution: The cable from the network wall jack must be connected to the connector marked
SW, and if there is a PC, it must be connected to the connector marked PC, otherwise the
IP250D will not function.
2.6 ARRANGING THE IP250D ON THE DESK
Route the network cable toward the rear of the keyset and attach the desk/wall
mounting bracket by inserting the snap fasteners into the matching holes in the base.
Place the unit at a convenient location on the desk. Be sure to replace the handset on the
cradle and ensure that the hookswitch is properly depressed by the weight of the earpiece
of the handset.
2.7 MOUNTING THE IP250D ON A WALL
The IP250D can be mounted on a wall or other vertical surface. To do so, the desk/wall
mounting bracket should be rotated 180 degrees, compared to the desk mounting
position. Use screws (and anchors, if necessary) to match the hole pattern in the bracket.
The wall mounting clip near the hookswitch should be removed and re-installed after
rotating it 180 degrees. To remove the clip, push it firmly toward the hookswitch.
The clip will hold the handset in the cradle and cause it to depress the hookswitch when
the phone is not in use.
2.8 CONNECTING A HEADSET TO THE IP250D
Two types of headsets may be connected to the IP250D:
a) The type that replaces the handset and connects to the RJ-10 handset cord receptacle
b) The type that connects to a 2.5 mm diameter jack (located on the right front side
of the keyset)
When using the 2.5 mm type, the handset should be left in the cradle, such that it
depresses the hookswitch. Please follow the headset manufacturer’s instructions when
using the type that replaces the handset.
Note: The handset, headset and speakerphone devices have special rules that describe their
modes of use, as described in section 4.7.

CONFIGURING THE IP250D
3 Configuring the IP250D
Once the IP250D has been unpacked, set up on the desk (or mounted to a wall), and
connected to the network, the network administrator should be notified that the unit is
ready for network configuration and activation. Once the unit has been configured and
activated, it will receive power from the network and begin to function.
Note: The IP250D will not function until it has been configured and activated by the
network administrator.
ꢀ
The user cannot make any changes to the network configuration of the IP250D, but can
make certain changes to suit personal preferences, such as volume settings, ringer tones,
speed-dial phone numbers and the like. These steps are covered later in this manual.
This section contains information on how to access the device’s built in web pages for
further configuration. In order to access the built-in configuration web pages of the
device, you need to know its IP address. If you do not know the IP address of the unit,
refer to Appendix A for instructions on how to determine the unit’s IP address. If the IP
address is known, a web browser URL can be pointed to the address. Doing so will
display the device’s main configuration web page, which will look similar to that shown
below in Figure 3-1. The main configuration menu appears on the left of the screen. The
contents of this menu will differ depending on the purpose of the device, the VoIP proto-
col which is running on the device (if any), and whether the device is executing the main
application or the downloader application.
Note the following web browser requirements:
• Javacript must be enabled.
• For optimum viewing of the device's web configuration pages, we suggest
configuring your system display to a minimum viewing resolution of 800x600
and your browser display maximized to fill the viewing area.
• To avoid potential javascript execution errors, we also recommend using
Internet Explorer 4.0 or higher, or Netscape 4.0 or higher.
3.1 THE HOME PAGE
The home page is the first page displayed when the device’s web pages are accessed. It
shows how long the device has been running since its last reboot, the IP address the
device is currently using, whether or not the device is password protected, and also dis-
plays the main application and downloader application firmware versions. To navigate
the system settings, click on the selections to the left side of the page.

CONFIGURING THE IP250D
3.3.1 MGCP Settings
This sub-page allows configuration of the MGCP server and device endpoint settings.
Enter the address and port number of the MGCP Call Agent. The address may be an IP
address or the name of the server.
If no Call Agent address is entered, the device will attempt to self-provision a Call Agent
using a DNS query. For this to be successful, ensure that the DNS settings on the device
include a DNS server address which is configured with the Call Agent address, and will
respond to the query, and the appropriate domain name of the network.
For the endpoint, configure the domain name of the device as it will appear in all MGCP
signaling transactions with the call agent. For example, if the domain name is set to
"teledex.com", configure the domain name to read: aaln/[email protected]
If the domain name is left blank, the device’s IP address will be used as the domain name.
For example: aaln/1@[192.168.1.100]
Enter the maximum delay before the device will send out the RSIP message after it
powers up. The actual RSIP time-out will be a random number between zero and the
number entered on this page. If you wish for the device to immediately send the RSIP
after powering up, enter the value zero.
Under the compatibility section, select which MGCP "Profile" is to be used. Finally,
select whether the MGCP stack should employ message "piggybacking" whenever
possible when sending packets. Some older call agents do not support piggybacked
messages. Press SAVE MGCP SETTINGS to save the new values. Reset the unit to have the
new settings take effect.
3.3.2 OOB Signalling Settings
This sub-page configures the handling of out-of-band telephony events signalling using
the RFC2833 protocol over RTP. First, select whether telephony events are to be sent
using RFC2833, and the destination port value which should be used for the signalling.
Select whether any voice packets are to suppressed (dropped) during the transmission of
RTP RFC2833 signalling packets. Some networks may enforce this to ensure that no
extra bandwidth is consumed by the signalling. Select whether the inband audio DTMF
is to be "squelched" (i.e. the device on the other end will not hear any audio DTMF).
Select the ABCD event transition handling mode to be used. In transition mode,
signalling packets are only sent when the ABCD event changes state. In continuous mode,
ABCD packets are continuously sent for a particular ABCD state. Press SAVE RFC2833
SETTINGS to save the new values.

options to configure the SIP server and device endpoint settings.
3.4.1 SIP Settings
This page allows configuration of the SIP server and endpoint settings. Enter the IP
address and port value of the SIP server. If no SIP server address is entered, the device will
attempt to self-provision a SIP server using a DNS query. For this to be successful, ensure
that the DNS settings on the device include a DNS server address which is configured
with the SIP server address and will respond to the query, and the appropriate domain
name of the network. Enter the domain name of the network. For the endpoint, set the
dial plan to be used by all lines, and select the transport method to be used in the SIP
signalling (either UDP or TCP). For each line on the endpoint (note: the IP phone has a

USING THE IP250D
4 Using the IP250D
This section describes how to use the IP250D. The references and actions associated to
the "LINE 1", "LINE 2" keys and LEDs apply to the SIP version of the IP250D only.
The "LINE 1" and "LINE 2" keys and LEDs are inactive on the MGCP version.
4.1 TELEPHONE IDLE
The IP250D is in an idle state when the handset is on-hook, the headset and speaker are
off, and the user is not attempting to use or configure the phone in any way. The IP250D
displays the date and time when the telephone is in an idle state. The date and time may
be displayed in a MM-DD-YY, MM-DD, DD-MM-YY, or DD-MM format for the date
and a 24-hour or 12-hour format for the time. The phone also displays its extension
number or telephone number.
4.2 INCOMING CALL NOTIFICATION
The phone provides notification of an incoming telephone call in three ways:
1) The phone rings using a tone chosen by the user. Different ring tones may be
chosen for internal and external calls.
2) During an incoming call, the IP250D flashes the LED for line 1, if no lines are
active. If line 1 is active but line 2 is not, the phone flashes the LED for line 2,
and if line 2 is active but Line 1 is not, the phone flashes the LED for line 1.
3) The IP250D displays any caller information (if available) on its display.
4.3 RECEIVING A CALL
The IP250D allows the user to receive a call and establish a virtual audio connection with
the other party through the handset, speakerphone, or headset:
HANDSET – From the idle state, the user may receive a call by lifting the handset, thereby
placing the IP250D off-hook. If the user is already conducting a conversation with
another party, the call may be answered using the handset by placing the initial party on
hold and pressing the LINE 1 or LINE 2 key corresponding to the new call. If the phone is
idle but the handset is already off-hook when a call arrives, the user can receive the call
by hanging up the handset and lifting it again, or by pressing the LINE 1 or LINE 2 key
corresponding to the new call. The user will be able to identify the proper line key to
press because the LED above that key will be flashing.

USING THE IP250D
HEADSET – For a SIP version phone only, the user may receive a call using the headset by
pressing the LINE 1 or LINE 2 key corresponding to the new call when a headset is plugged
in and the handset is down. The IP phone hardware accommodates two types of headsets,
and the software routes the virtual audio connection to both headset jacks whenever at
least one headset is plugged in. The software also routes the audio to the headset when
the handset is down.
SPEAKERPHONE – The user may receive a call on the speakerphone by pressing the
SPKR/HSET key or by pressing the LINE 1 or LINE 2 key corresponding to the new call if
the headset is not plugged in and the handset is on-hook. Once the call is received, the
caller information disappears, the flashing of the LED and ringing stops, and a virtual
audio channel for conversation is opened.
4.4 PLACING A CALL
The IP250D allows the user to initiate a call through the handset, speakerphone, or
headset as follows:
HANDSET – From the idle state, the user may initiate a call by lifting the handset and
placing the phone off-hook. The user should then listen for a dial tone and dial the
number or extension of the call recipient. The user may also initiate a call while already
on the line with another party.
HEADSET – The user may initiate a call from the idle state using the headset, by plugging
the headset in, keeping the handset on-hook, and pressing the SPKR/HSET key or pressing
the LINE 1 or LINE 2 key.
SPEAKERPHONE – The user may initiate a call on the speakerphone when the handset is
down and the headset is unplugged by pressing the SPKR/HSET key or pressing the LINE 1
or LINE 2 key.
When initiating a call, the LED corresponding to the appropriate line is lit continuously
and the number dialed is shown on the display. Once the user has finished dialing and a
virtual audio connection with the other party has been established, the display changes to
show the elapsed call time. All of the digits dialed while initiating the call are erased from
the display. The user may also dial using speed dial and directory features. During a
telephone conversation, The phone displays the time elapsed for the active call until the
conversation is terminated. The time is displayed in HH:MM:SS format. In the unlikely
event that a call lasts for 100 hours or more, the display simply rolls over to start at 0,
instead of consuming an extra character on the display. The LED for the appropriate line
is lit continuously.

USING THE IP250D
The volume of the handset can be increased or decreased by pressing the up or down
volume keys. The volume buttons adjust the volume for the currently active call. The
volume settings may be saved for future calls by setting the volume to the desired level
and pressing the PROGRAM key immediately afterward.
4.5 DTMF SIGNALING
Virtually all telephony applications, such as those used by customer service centers and
calling cards, require touch tone data entry. For example, calling cards frequently request
that the user press ‘1’ for English and ‘2’ for Spanish. The technical name for the tones
generated by pressing digits on the keypad is dual tone multiple frequency, or DTMF.
The IP250D supports DTMF signaling by generating DTMF tones over the virtual audio
connection. The keys pressed during telephone calls are also displayed on the display
below the call duration indicator. The digits begin appearing on the second row (left side)
of the display. Each line on the display has room for sixteen digits; the display scrolls to
the left when the user dials a number exceeding sisxteen digits in length, and will
continue to scroll as more numbers are dialed.
4.6 TERMINATING A CALL
You may terminate a call by various methods, depending upon whether you are using the
handset, speakerphone or a headset:
• If using the handset, the call may terminated by replacing the handset on
the cradle.
• If using a headset, the call may be terminated by pressing the SPKR/ HSET key, or
by lifting the handset off the cradle and then putting it down again on the cradle.
• If using the speakerphone, the call may be terminated by pressing the SPKR/HSET
key, or by picking up the handset off the cradle and putting it down again.
If no other call is active, the phone will revert to the idle state upon the termination of a
conversation. If another call is active, and therefore on hold, it will remain on hold until
the user takes it off hold, or the other party terminates the conversation. In either case,
the software will turn off the LED corresponding to the formerly active line.
4.7 HEADSET AND SPEAKERPHONE USAGE
The IP250D software routes the voice to the handset, speakerphone, or headset based
upon the actions of the user. The software gives the highest priority to the handset,
secondary priority to the headset, and lowest priority to the speakerphone. If a call is
initiated while the handset is off-hook, or if a call is received and the user takes the
handset off hook, the audio channel will be routed through the handset. The headset
may be activated by pressing the SPKR/HSET key while on the handset, and then putting

USING THE IP250D
the handset down, or by pressing the SPKR/HSET key, or the LINE 1 or LINE 2 keys to
initiate or receive the call while the handset is on hook.
The audio channel is routed to the speakerphone if the headset is not plugged in, and to
the headset jack if the headset is plugged in. To switch from headset to speakerphone,
unplug the headset from the headset jack. To switch from speakerphone to headset, plug
the headset back in. In order to switch from the speaker or headset back to the handset,
pick up the handset. The software will not allow more than one speaking device to be
used at a time. While the speakerphone or headset is active, the LED above the
SPKR/HSET button on the keypad will be illuminated.
4.8 HOLD AND MULTIPLE LINES
While engaged in conversation on a particular line, the HOLD feature may be used to
mute both the microphone and speaker on the handset, speakerphone, or headset
(depending on which is in use) by pressing the HOLD key. Placing a call on hold allows
the alternate line to be used to either receive or initiate a new call, without disconnecting
the first call.
Note: Placing a call on hold does not allow access to any functions, such as programming or
phone book, for example, that are not available in normal conversation mode.
ꢀ
In order to indicate that a call is on hold (SIP phone only) the software flashes the LED
above the button for the line on hold. The flashing pattern for HOLD is slow and contin-
uous, as opposed to the flashing pattern for an incoming call notification, in which the
LED flashes quickly for two seconds with each ring and then turns off for several seconds
between rings.
When a call is on hold, the system continues to count the time elapsed for the call, even if
the user switches lines. For example, if the user speaks to another party for thirty seconds
and then places that party on hold for thirty more seconds, the display will read
"00:01:00" when the other party is taken off hold. The call will cease being on hold if
the other party hangs up, or if the user releases the hold by pressing the HOLD key, or the
key corresponding to the line on hold.
The IP250D (SIP version) allows for two virtual lines to be active at any time. The
functionality of the two lines is similar to the feature of call waiting on analog telephones,
except that you may use the line keys to switch between lines, instead of using the hook
switch. The virtual lines are accessed through the LINE 1 and LINE 2 keys; the status of
any line is displayed through the LED above the corresponding button as follows:

USING THE IP250D
• When a line is inactive, the corresponding LED is off.
• When a line is ringing, the corresponding LED flashes quickly for two seconds
with each audible ring and turns off in between rings. This flashing pattern is used
even when the ring is not audible.
• When an user is initiating a call, or conducting a conversation on a particular line,
the corresponding LED is illuminated continuously.
• When a line is on hold, the corresponding LED flashes slowly.
The IP250D software gives notification of a second incoming call regardless of whether
the user is initiating a call, conducting a conversation, receiving another call, or on hold
on the first line. In the descriptions below of scenarios for the second incoming call, the
descriptions of line 1 and line 2 can be interchanged freely except where otherwise noted.
• If the user is initiating a call on line 1 when the second call arrives, the LED for
line 2 will also begin flashing, and the call information for the incoming call will
be shown on the display. The second call may be received by pressing on the
LINE 2 key, by hanging up the handset and picking it up again, or by pressing the
SPKR/HSET key once to hang up, and once again to pick up if using the speaker
phone or headset. To continue initiating the original call, simply continue dialing.
The display will change back to the dialing screen for each subsequent key
pressed.
• If the user is conducting a conversation on line 1 when a call arrives on line 2,
a half-second tone will sound on the receiver of the speaking device (handset,
speakerphone, or headset), the LED for line 2 will begin flashing, and the call
information for the incoming call is shown on the display. If the user begins
pressing keypad buttons for DTMF signaling, the display will change to the
DTMF signaling screen, then change back to the incoming call screen after six
seconds. To receive the second call, either press the LINE 2 key, which will auto
matically place the line 1 call on hold, or press HOLD and then the LINE 2 key.
Otherwise, the phone will produce a half-second tone on the receiver of the
speaking device every twelve seconds until the calling party on line 2 hangs up or
the incoming call is sent to the voicemail server. The incoming call may not be
forwarded directly to voicemail.
• If one call arrives, and then another call arrives before the user can receive the
first call, the ringer will ring as usual, but both the LEDs for lines 1 and 2 will
flash. In addition, the display will alternate every six seconds between the infor
mation for the call on line 1 and the information for the call on line 2. To answer
the call on line 2 first, press the LINE 2 key to place the call on speakerphone and
then pick up the handset if you so desire.

USING THE IP250D
• If a call arrives on line 1 while a conversation is being conducted on line 2, the
conversation on line 2 may be terminated by hanging up the call. After the call on
line 2 has been terminated, the phone begins using the normal ring tone for the
call on line 1 rather than the half-second tone on the speaking device.
In addition to accommodating incoming calls on the second virtual line, the software
allows outgoing calls to be made on the second line. This can be done by placing the first
line on hold, and then dialing the destination number (using the keypad, speed dial, or
the directory.) Both lines may be placed on hold simultaneously. If both lines are on hold
and the HOLD key is pressed, the call that was first placed on hold will be the one that is
released.
4.9 MUTING A CALL
Press the MUTE key to mute the microphone of either the handset, headset, or speaker-
phone, depending on which is in use. A green LED indicates that the phone is in "mute"
mode. To remove mute, repress the MUTE key again.
4.10 TRANSFERRING A CALL
To transfer a call, press the XFER key, then dial the number to which the call is to be
transfered When either a ring or a dial tone is heard, the phone may be hung up to com-
plete the transfer.
4.11 REDIALING THE LAST NUMBER DIALED
The REDIAL key allows the last ten numbers dialed to be viewed. Press REDIAL and use
the SCROLL keys to see the last ten numbers dialed. Press the keys 0-9 on the keypad to
select the desired number. (Pressing the ‘0’ key will dial the tenth number on the list.)
4.12 FORWARDING ALL CALLS
Your calls may be forwarded to either an IP phone or standard analog or digital phone,
including wireless phones. To do this, place the phone off hook in either handset or
headset mode. Press the FWD key. Dial the number to which calls are to be forward.
To deactivate call forwarding, go off hook and press the FWD key. While the phone is in
the call forward state, the message FORWARDING TO: and the number to which calls are
to be forwarded is displayed on the LCD.

TROUBLESHOOTING AND CARE
5 Troubleshooting and Care
This section covers troubleshooting and caring for your IP250D.
5.1 BASIC TROUBLESHOOTING MEASURES
If the IP250D does not seem to function as expected, there are several troubleshooting
techniques that may be tried before contacting the network administrator.
5.1.1 Disconnect From the Network
Unplug the network patch cable from the wall jack. Wait at least fifteen (15) seconds,
then plug the cable back into the same jack. The IP250D will attempt to re-establish
contact with the SIP server or Call Agent. In many cases of malfunction, this should
restore normal operation.
Warning: Risk of electrical shock! Dangerous voltages may be present on the exposed
terminals of the network patch cable after it is plugged into the network wall jack.
WARNING
5.1.2 Disconnect the PC
If there is a PC or other network device connected to the “PC” network port, disconnect
the patch cable to the PC from the base of the keyset, then perform the actions from sec-
tion 5.1.1, Disconnect From the Network.
5.1.3 Check the Cords and Cables
If the previous two steps do not solve the problem, all of the cords and cables (including
handset cord and headsets) should be disconnected, inspected for dirt or corrosion, and
reconnected.
5.2 GENERAL TROUBLESHOOTING
SYMPTOM: There is no LED or display activity at power on.
SOLUTION:
Check that the power supply unit (PSU) is properly connected.

agent or SIP server) does not appear to work.
SOLUTION A: Ensure that the DNS server is capable of servicing DNS TXT or SRV
queries, and that it is configured to respond with the correct server
information when queried.
SOLUTION B: If the device is configured via DHCP, ensure that the DHCP server has
provided the correct DNS server and domain name information.
SOLUTION C: If the device network information has been statically assigned (i.e. not via
DHCP), ensure that the DNS server IP address is correct, and that the
network domain name has been provided and is correct.
SYMPTOM: The web browser complains often about errors on the page.
SOLUTION : Ensure that the web browser supports frames and that javascript is enabled.

APPENDICES
If the main application is executing at the time, the device will automatically reboot
itself into the downloader mode and begin the download process. If the downloader
application is executing at the time, the download process will begin. The download
status will be displayed when the image download process is complete. After the
download is completed, the download status page will be displayed. If the download
repeatedly fails, please contact your technical support representative.
A typical download takes about one minute, although it may take up to two minutes if
the network link is slow or congested.
Warning: Once the download is in progress, it MUST be allowed to complete in its entirety, or
the main application image will be destroyed. If an irrecoverable error occurs, reboot the
device. It will automatically start in the downloader application and allow you to reattempt
a download of the new firmware image.
WARNING
7 Appendix A: Determining the IP Address
This section provides instructions on how to determine the IP address of a unit. The
following general instructions can be followed to determine the IP address of a unit:
1) Press the SETTINGS button to access the unit’s settings configuration menu.
2) Press ‘2’ to select the NETWORK CFG menu.
3) Press ‘1’ to select the HOST CONFIG menu.
4) Press ‘1’ to view the host’s IP address.
8 Appendix B: Safe Bootup Modes
It is possible to boot the downloader application on the unit into a ‘safe’ mode. The
following safe modes exist:
1) FORCE DHCP MODE: This will force the unit to execute the downloader application
and attempt to obtain an IP address via DHCP.
2) FORCE FIXED IP MODE: This will force the unit to execute the downloader application
and use the fixed IP address configured in the unit. If no fixed IP has been configured
for the device, the unit will attempt to obtain an address via DHCP.
3) FORCE IP ADDRESS OF 10.1.0.54: This will force the unit to execute the downloader
application and use the IP address 10.1.0.54. A computer on the same logical
network (10.1.0.x) of the device (e.g. 10.1.0.39) can now access the device’s web
configuration pages. You can then proceed to reconfigure the network settings
(LAN option).

22
APPENDICES
Once the downloader application is running, the unit’s web page will display downloader
options only, and not application choices such as protocol (SIP or MGCP) and audio
codecs. In any of the above safe modes, VLAN will be disabled.
8.1 ’SAFE’ MODES ON AN IP PHONE
The IP Phone can be forced into a ‘safe’ downloader mode by doing the following:
1) Take the handset off-hook.
2) To restore the device's factory defaults (no call agent, boot using DHCP),
continue holding down the ‘1’ key for four (4) seconds during power up.
The IP250D’s LCD will display a countdown during the four second timeout.
After four seconds, the config file will be erased, and the unit will reboot the
main application.
3) To use 10.1.0.54, press the star (*) key during power up.
4) To use a previously-configured fixed IP address, press the ‘0’ key during power
up. If no fixed IP address was previously configured, the unit will use DHCP to
acquire an IP address.
5) To use DHCP, press the pound (#) key during power up.
9 Appendix C: Restoring Factory Defaults
This section describes how to restore the factory default settings of your IP250D.
Restoring the default settings is equivalent to clearing the internal ROM configuration
file. The IP250D can be restored to its default settings by doing the following:
1) Take the handset off hook.
2) Power cycle the device while holding down key ‘1’ for four (4) seconds. The
display will count down, indicating the time remaining until the factory defaults
will be restored. After four (4) seconds, the message DEFAULTS RESTORED will be
displayed on the LCD, and the phone will reboot.
The same result can be obtained by using the t2burn application and specifying an empty
configuration file. For example:
t2burn NONE NONE empty.cfg <platform>
(where empty.cfg is an empty config file).
Note: It is important that the ‘1’ key be held for four (4) seconds from the point at which
the unit reboots. Releasing the ‘1’ key before four seconds elapse will abort the restoration
and continue with the normal booting procedure.

10 Appendix D: Dial Plans
The IP Phone SIP code will allow provisioning (via web browser) of the dial plan. A dial
plan gives the unit a map to determine when a complete number has been entered and
should be passed to the gatekeeper for resolution into an IP address. Dial plans are
expressed using the same syntax as used by MGCP NCS specification. The formal syntax
of the dial plan is described by the following notation:
DIGIT ::= "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9"
TIMER ::= "T" | "T"
LETTER ::= DIGIT | TIMER | "#" | "*" | "A" | "A" | "B" | "B" | "C" | "C"
| "D" | "D"
RANGE ::= "X" | "X" -- MATCHES ANY DIGIT
| "[" LETTERS "]" -- MATCHES ANY OF THE SPECIFIED LETTERS
LETTERS::= SUBRANGE | SUBRANGE LETTERS
SUBRANGE::= LETTER -- MATCHES THE SPECIFIED LETTER
| DIGIT "-" DIGIT -- MATCHES ANY DIGIT BETWEEN FIRST AND LAST
POSITION::= LETTER | RANGE
STRINGELEMENT::= POSITION -- MATCHES ANY OCCURRENCE OF THE POSITION
| POSITION "." -- MATCHES AN ARBITRARY NUMBER OF OCCURRENCES
INCLUDING 0
STRING ::= STRINGELEMENT | STRINGELEMENT STRING
STRINGLIST::= STRING | STRING "|" STRINGLIST
DIALPLAN::= STRING | "(" STRINGLIST ")"
A dial plan, according to this syntax, is defined either by a (case insensitive) string or by a
list of strings. Regardless of the above syntax, a timer is only allowed if it appears in the
last position in a string (12T3 is not valid). Each string is an alternate numbering scheme.
The unit will process the dial plan by comparing the current dial string against the dial
plan, if the result is under-qualified (partial matches at least one entry) then it will do
nothing further. If the result matches or is overqualified (no further digits could possibly
produce a match) then send the string to the gatekeeper and clear the dial string.
The timer T is activated when it is all that is required to produce a match. The period of
timer T is four (4) seconds. For example, a dial plan of (xxxT|xxxxx)will match
immediately if five (5) digits are entered, it will also match after a four (4) second pause
when three (3) digits are entered.

APPENDICES
10.1 SAMPLE DIAL PLANS
Simple Dial Plan
Allows dialing of seven (7) digit numbers (e.g. 5551234) or an operator on 0.
Dial plan is (0T|xxxxxxx)
Non-Dialed Line Dial Plan
As soon as handset is lifted, the unit contacts the gatekeeper (used for systems where
DTMF detection is done in-call). Dial plan is (x.)i.e. match against 0 (or more) digits.
(Note: the dot ‘.’)
Complex Dial Plans
Local operator on 0, long distance operator on 00, four-digit local extension number
starting with 3, 4 OR 5, seven-digit local numbers prefixed by an 8, two-digit star services
(e.g. *69), ten-digit long distance prefixed by 91, and international numbers starting with
9011+ variable number of digits, are all examples of complex dial plans. The dial plan
rule for these is:
(0T|00T|[3-5]xxx|8xxxxxxx|*xx|91xxxxxxxxxx|9011x.T)
11 Appendix E: Tone and Ring Cadence Configuration
The various tone patterns generated by the IP Phone are all configurable via the standard
config variable process. In addition, the ring cadence patterns used are also configurable.
This section describes how to configure tones and ring cadence patterns.
11.1 TONE CONFIGURATION
The "language" for specifying the tone components is quite simple. They can be
summarized by the following BNF:
Freqval ::= frequency in Hertz
Powerval ::= power in Dbm0
Timeval ::= time in milliseconds
Repeatval ::= # of cycles to repeat
Tonename ::= "DTMF_0" | "DTMF_1" | "DTMF_2" | "DTMF_3" |
"DTMF_4" |"DTMF_5" | "DTMF_6" | "DTMF_7" | "DTMF_8" | "DTMF_9"
|"DTMF_STAR" | "DTMF_POUND" | "DTMF_A" | "DTMF_B" |"DTMF_C" |
"DTMF_D" |"DIALTONE" | "BUSY" | "RINGBACK" | "CALLWAITING" |
