Microsoft—Polycom
Meeting Scenarios
Microsoft–Polycom integrated solution offers high quality point-to-point
and multipoint voice, and video conferencing calls (in any combination)
across communication devices, applications and services. This solution
empowers users to connect and share information in real-time regardless
of type of call. Polycom enhances Microsoft’s environment by:
•
enabling Polycom endpoints (VSX and PVX) to be added to Office
Communicator and Windows Messenger buddy list
•
bridging between Microsoft SIP-only environment and legacy
ISDN, PSTN and H.323 endpoints
•
•
displaying the user/endpoint presence in the buddy list
starting a point-to-point or multipoint meeting directly from
Polycom endpoints, Office Communicator and Windows
Messenger.
In the Microsoft—Polycom environment, two arrays of meeting
scenarios are available; Those intended for Windows Messenger and
Office Communicator that do not leverage and are not based on SIP-CX
conferencing and those intended for Office Communicator and are based
on SIP-CX conferencing.
Windows Messenger and Office Communicator scenarios that do not
leverage and are not base on SIP-CX conferencing
The Meeting Rooms and/or Entry Queues defined in Polycom MGC

When using Office Communicator that supports the use of DTMF codes, a
conference password can be implemented as a security measure. Office
Communicator users joining the conference enter the conference
password using the keypad from the Audio Controls pane. In addition, the
conference video layout can be changed via Click&View (a feature of
using Polycom endpoints and the MGC MCU).
Participants using an H.323 connection dial a string composed of the IP
Network Service Prefix and the conference numeric ID. For example, if
the IP Network Service Prefix is 34 and the conference Numeric ID is 2879,
H.323 participants will dial 342879 to connect to the conference.

Single Dial Entry Queue
An Entry Queue is used as a special routing lobby to all Meeting Rooms
and conferences, enabling one dial-in number to be used for joining all
conferences. Participants are routed to the destination conference by
entering the conference ID using DTMF codes.
This scenario is supported only with Office Communicator. Windows Messenger
does not support DTMF codes.
In this mode, only one or a few Entry Queues are defined and added to
the Office Communicator contacts list, which keeps the list small and easy
to manage, while with Meeting Rooms, it requires each Meeting Room to
be defined and added to the contacts list resulting in a long list.
The Entry Queue is created and added to the buddy list of Office
Communicator. The target conferences (Meeting Rooms) are also created
in the MGC Manager application. This is the recommended meeting
scenario.
To start a video conference using the Meeting Room in Office
Communicator:

Ad-hoc Entry Queue and Conference Creation
This procedure is similar to the Single Dial Entry Queue procedure, with
the exception that the Meeting Room is not defined in the MGC Manager
in advance and the ongoing conference is created on-the-fly.
In addition, the Entry Queue must be set as Ad-hoc, and the conference
Profile must be assigned to it.
When the user enters the target conference ID, the MCU checks for an
ongoing conference with this ID. If such a conference does not exist, a new
conference is created using the parameters defined in the conference
Profile. The conference ID sent by the user (using DTMF codes) is
assigned to the new conference.
This scenario is supported only with Office Communicator and is the
recommended scenario for Office Communicator users as no Meeting Rooms
have to be defined in advance and stored in the MCU memory. This scenario is
not supported with Windows Messenger as it does not support DTMF codes.
For a detailed description of Ad-hoc conferencing and External database
Authentication, see Chapter 4.

Dial-out to Conference Participants
In this scenario, a video conference is scheduled on a Polycom MCU and it
includes predefined participants; Office Communicator, Windows
Messenger and other SIP and non-SIP users.
At the scheduled time the conference is activated and the MCU
automatically dials out to the predefined participants and connects them
to the conference.
Once dial out is attempted by the MCU, the INVITE request will be routed
to each participant's UA assuming participant's UA is registered with the
LCS at that time.
For a detailed description of the conference definition, see the MGC
Manager User’s Guide, Volume I, Chapter 4.

The New Phone Number dialog box opens.
The MGC system supports the use of a dial plan for parsing and
interpreting a received number as an H.323 alias, SIP URI or ISDN
number to be used accordingly by the MGC system for initiating a
callback to that device.
The E.164 number (no SIP URI) is converted into a SIP URI by Office
Communicator, inserted into the Refer-To field and sent in the
REFER transaction to the MGC system.
For example: the user enters "1234567". The Refer-To field sent by
Office Communicator to the MGC will have:
"sip:1234567@domain;user=phone".
Now the MGC unit can use the dial plan, as defined in system.cfg, to
parse and interpret the "1234567" string and initiate a corresponding
H.323, SIP, ISDN or PSTN dial out.
The REFER request sent to MGC contains a "ms-associated-sip-uri"
field that includes the invitee’s URI. The MGC system can use this
information to identify the name of the new participants in
notifications it sends to Office Communicator conference watchers.

•
•
•
•
Conference name or Numeric ID
Leader (chairperson) password
Participant code (conference entry password)
Domain
Optional parameters (if the conferencing server—MCU is connected to
PSTN/ISDN lines):
•
•
Toll dial-in number (assigned to the conference)

In the Conferencing Information section, enter the following
information:
Table A-1 Conference Information Parameters
Field
Description
Conference ID
Enter the name assigned to your Meeting Room in
the MGC environment. If an Entry Queue is used for
conference access, use numerals.
Leader code
Enter the password defined for your conference in
the MGC environment that identifies you as
conference chairperson and enables you to control it
while it is running.
Participant code
Enter the entry password defined for your conference
in the MGC environment. This password enables you
to start and join your conference.
Domain
Toll
Enter your domain name. This is required for
callback.
Optional. Enter the dial-in number (PSTN or ISDN)
assigned to the Meeting Room in MGC environment.
The PSTN / ISDN dial-in numbers can be either the
Meeting Room dial-in numbers or an Entry Queue
number. Using a single-dial Entry Queue and
specifying the target conference ID via DTMF
enables you to use a limited number of PSTN dial-in
numbers, which are precious resources and it might
not be feasible to allocate a separate individual
number for each Meeting Room.
Toll free
Optional. Enter the toll free dial-in number (PSTN or
ISDN) assigned to the Meeting Room in MGC
environment. Toll free numbers are usually a 1-800
number assigned to the Entry Queue and not an
individual conference number. Therefore, conference
ID / name specified should consist of numerals and
not characters.
