MAKING PHONE CALLS  
HANDSET, SPEAKER AND HEADSET MODE  
The GXP2120/GXP2110/GXP2100/GXP1450 allows users to switch among handset, speaker or headset  
when making calls. Press the Hook Switch to switch to handset; press the Headset button to switch to

MULTIPLE SIP ACCOUNTS AND LINES  
GXP2120 can support up to 6 independent SIP accounts; GXP2110/GXP2100 can support up to 4  
independent SIP accounts; GXP1450 can support up to 2 independent accounts. Each account is capable  
of independent SIP server, user and NAT settings. Each of the line buttons is "virtually" mapped to an  
individual SIP account. In off hook state, select an idle line and the dial tone will be heard.  
To make a call, select the line you wish to use. The corresponding LINE LED will light up in green. The  
user can switch lines before dialing any number by pressing the LINE buttons.  
For example: If 2 independent accounts are registered on GXP2120/GXP2110/GXP2100/GXP1450, when  
LINE 1 is pressed, the LINE 1 LED will light up in green. If LINE 2 is pressed, the LINE 2 LED will light up in  
green and the subsequent call will be made through SIP account 2.  
Incoming calls to a specific account will attempt to use its corresponding LINE if it is not in use. When the  
"virtually" mapped line is in use, the phone will flash the other available LINE in red. A line is ACTIVE when  
it is in use and the corresponding LED is red.

MAKING CALLS USING IP ADDRESSES  
Direct IP Call allows two phones to talk to each other in an ad-hoc fashion without a SIP proxy. VoIP calls  
can be made between two phones if:  
Both phones have public IP addresses; or  
Both phones are on the same LAN/VPN using private or public IP addresses; or  
Both phones can be connected through a router using public or private IP addresses (with necessary  
port forwarding or DMZ).  
To make a direct IP call, please follow the steps below:  
Press MENU button to bring up main menu;  
Select "Direct IP Call" using the navigation arrow keys;  
Press MENU to enter the Direct IP Call mode;  
Input the 12-digit target IP address (Please see example below);  
Press the "More" softkey to make sure the softkey selection "IPv4" or "IPv6" is correctly selected  
depending on your network environment;  
Press "OK" softkey to dial.  
For example:  
If the target IP address is 192.168.1.60 and the port is 5062 (i.e., 192.168.1.60:5062), input the following:  
192*168*1*60#5062. The * key represents the dot (.), the # key represents colon (:). Wait for about 4  
seconds and the phone will initiate the call.  
Quick IP Call Mode:  
The GXP2120/GXP2110/GXP2100/GXP1450 also supports Quick IP Call mode. This enables the phone  
to make direct IP calls using only the last few digits (last octet) of the target phone's IP address. This is  
possible only if both phones are under the same LAN/VPN. This simulates a PBX function using the  
CMSA/CD without a SIP server. Controlled static IP usage is recommended.  
To enable Quick IP Call Mode, go to phone's Web GUI->Advanced Setting page, set "Use Quick IP Call  
Mode" to "Yes". Click on "Update" on the bottom of the Web GUI page to take the change. To make Quick  
IP Call, take the phone off hook first. Then dial #xxx where x is 0-9 and xxx<255. Press # or SEND and a  
direct IP call to aaa.bbb.ccc.XXX will be completed. "aaa.bbb.ccc" is from the local IP address regardless  
of subnet mask. The number #xx or #x are also valid. The leading 0 is not required (but it's OK).

For example:  
192.168.0.2 calling 192.168.0.3 -- dial #3 followed by # or “SEND”;  
192.168.0.2 calling 192.168.0.23 -- dial #23 followed by # “SEND”;  
192.168.0.2 calling 192.168.0.123 -- dial #123 followed by # “SEND”;  
192.168.0.2: dial #3 and #03 and #003 results in the same call -- call 192.168.0.3.  
Note:  
The # will represent colon ":" in direct IP call rather than SEND key as in normal phone call;  
If you have a SIP server configured, direct IP call still works. If you are using STUN, direct IP call will  
also use STUN;  
Configure the "User Random Port" to "No" when completing direct IP calls.  
ANSWERING PHONE CALLS  
RECEIVING CALLS

SHARED CALL APPEARANCE (SCA)  
The GXP2120/GXP2110/GXP2100/GXP1450 phone supports shared call appearance by Broadsoft  
standard. This feature allows members of the SCA group to shared SIP lines and provides status  
monitoring (idle, active, progressing, hold) of the shared line. When there is an incoming call designated  
for the SCA group, all of the members of the group will be notified of an incoming call and will be able to  
answer the call from the phone with the SCA extension registered.  
All the users that belong to the same SCA group will be notified by visual indicator when a user seizes the  
line and places an outgoing call, and all the users of this group will not be able to seize the line until the line  
goes back to an idle state or when the call is placed on hold (with the exception of when multiple call  
appearances are enabled on the server side).  
In the middle of the conversation, there are two types of hold: Public Hold and Private Hold. When a  
member of the group places the call on public hold, the other users of the SCA group will be notified of this

"Shared Line". If the user requires more shared call appearances, the user can configure multiple line  
buttons to be "shared line" buttons associated with the account.

CONFIGURATION VIA WEB BROWSER  
The GXP2120/GXP2110/GXP2100/GXP1450 embedded Web server responds to HTTP/HTTPS  
GET/POST requests. Embedded HTML pages allow a user to configure the IP phone through a Web  
browser such as Microsoft’s IE, Mozilla Firefox and Google Chrome.  
To access the Web GUI:  
1. Connect the computer to the same network as the phone;  
2. Make sure the phone is turned on and shows its IP address. You may check the IP address by  
pressing SwitchSCR softkey or go to MENU->Status;  
3. Open a Web browser on your computer;  
4. Enter the phone’s IP address in the address bar of the browser;  
5. Enter the administrator’s login and password to access the Web Configuration Menu.  
Note:  
The computer has to be connected to the same sub-network as the phone. This can be easily done by  
connecting the computer to the same hub or switch as the phone connected to. In absence of a  
hub/switch (or free ports on the hub/switch), please connect the computer directly to the PC port on the  
back of the phone;  
If the phone is properly connected to a working Internet connection, the IP address of the phone will  
display in MENU->Status. This address has the format: xxx.xxx.xxx.xxx, where xxx stands for a  
number from 0-255. Users will need this number to access the Web GUI. For example, if the phone  
browser;  
The default login name for the administrator is "admin". The default administrator password is set to  
"admin". The default login name for the end user is "user" while the default user password is set to  
"123".  
When changing any settings, always SUBMIT them by pressing the UPDATE button on the bottom of  
the page. After submitting the changes in all the Web GUI pages, reboot the phone to have the  
changes take effect if necessary. All the options under Basic Setting and Account Setting, and most of  
the options under Advanced Settings do not require reboot after submitting the changes. Under  
Advanced Setting, the parameters on network configuration require reboot after update.  
DEFINITIONS  
This section describes the options in the phone's Web GUI. As mentioned, you can log in as an

e) [147] - any digit of 1, 4, or 7  
f) <2=011> - replace digit 2 with 011 when dialing  
g) | - the OR operand  
Example 1: {[369]11 | 1617xxxxxxx}  
Allow 311, 611, and 911 or any 10 digit numbers with leading digits 1617;  
Example 2: {^1900x+ | <=1617>xxxxxxx}  
Block any number of leading digits 1900 or add prefix 1617 for any  
dialed 7 digit numbers;  
Example 3: {1xxx[2-9]xxxxxx | <2=011>x+}

[3469]11 }  
Explanation of example rule (reading from left to right):  
^1900x. - prevents dialing any number started with 1900;  
<=1617>[2-9]xxxxxx - allows dialing to local area code (617)  
numbers by dialing 7 numbers and 1617 area code will be added  
automatically;  
1[2-9]xx[2-9]xxxxxx |- allows dialing to any US/Canada Number with  
11 digits length;  
011[2-9]x - allows international calls starting with 011;  
[3469]11 - allows dialing special and emergency numbers 311, 411,  
611 and 911.  
Note:  
In some cases where the user wishes to dial strings such as *123 to  
activate voice mail or other applications provided by their service  
provider, the * should be predefined inside the dial plan feature. An  
example dial plan will be: { *x+ } which allows the user to dial * followed  
by any length of numbers.

NAT SETTINGS  
If the devices are kept within a private network behind a firewall, we recommend using STUN Server. The  
following settings are useful in the STUN Server scenario:  
STUN Server (under Advanced Settings page)  
Enter a STUN Server IP (or FQDN) that you may have, or look up a free public STUN Server on the  
internet and enter it on this field. If using Public IP, keep this field blank.  
Use Random Ports (under Advanced Settings page)  
This setting depends on your network settings. When set to "Yes", it will force random generation of  
both the local SIP and RTP ports. This is usually necessary when multiple GXPs are behind the  
same NAT. If using a Public IP address, set this parameter to "No".

Firmware upgrades take around 60 seconds in a controlled LAN or 5-10 minutes over the Internet. We  
recommend completing firmware upgrades in a controlled LAN environment whenever possible.  
NO LOCAL TFTP/HTTP SERVERS  
For users that would like to use remote upgrading without a local TFTP/HTTP server, Grandstream offers a  
NAT-friendly HTTP server. This enables users to download the latest software upgrades for their phone via  
this server. Please refer to the webpage:  
Alternatively, users can download a free TFTP or HTTP server and conduct a local firmware upgrade. A  
free windows version TFTP server is available for download from :  
Instructions for local firmware upgrade via TFTP:  
1. Unzip the firmware files and put all of them in the root directory of the TFTP server;  
2. Connect the PC running the TFTP server and the phone to the same LAN segment;  
3. Launch the TFTP server and go to the File menu->Configure->Security to change the TFTP server's  
default setting from "Receive Only" to "Transmit Only" for the firmware upgrade;  
4. Start the TFTP server and configure the TFTP server in the phone’s web configuration interface;  
5. Configure the Firmware Server Path to the IP address of the PC;  
6. Update the changes and reboot the phone.  
End users can also choose to download a free HTTP server from http://httpd.apache.org/ or use  
Microsoft IIS web server.  
Note:  
When the phone boots up, it will send a TFTP or HTTP request to download the configuration file  
"cfgxxxxxxxxxxxx" where "xxxxxxxxxxxx" is the MAC address of the phone. If it is a normal TFTP or HTTP  
upgrade, the following messages “TFTP Error from [IP ADRESS] requesting cfg000b82023dd4 : File does  
not exist. Configuration File Download” can be ignored in the TFTP/HTTP server log.

A configuration parameter is associated with each particular field in the web configuration page. A  
parameter consists of a Capital letter P and 2 to 3 (Could be extended to 4 in the future) digit numeric  
numbers. i.e., P2 is associated with the “Admin Password” in the Web GUI->Settings->Advanced Settings.
