SIP Settings
If your network supports the Session Initiation Protocol (SIP), you can use SIP to connect IP calls.
The SIP protocol has been widely adapted for voice over IP communications and basic video conferencing;
however, many of the video conferencing capabilities are not yet standardized. Many capabilities also
depend on the SIP server.
The following are examples of features that are not supported using SIP:
● Cascaded multipoint in SIP calls.
● Meeting passwords. If you set a meeting password, SIP endpoints will be unable to dial in to a
multipoint call.
For more information about SIP compatibility issues, refer to the Release Notes for Polycom RealPresence
Group Systems.
To specify SIP settings:
1 In the web interface, go to Admin Settings > Network > IP Network > SIP.
2 Configure these settings.
Current Gatekeeper IP
Address
If you chose Off for the Use Gatekeeper field, the Current Gatekeeper IP
Address field is not displayed.
Displays the IP address that the gatekeeper is currently using.
Primary Gatekeeper IP
Address
• If you chose Off for the Use Gatekeeper field, the Primary Gatekeeper IP
Address field is not displayed.
• If you chose to use an automatically selected gatekeeper, this area displays the
gatekeeper’s IP address.
• If you chose to specify a gatekeeper, enter the gatekeeper’s IP address or name
(for example, 10.11.12.13 or gatekeeper.companyname.usa.com).
The primary gatekeeper IP address contains the IPv4 address the system registers
with. As part of the gatekeeper registration process, the gatekeeper might return
alternate gatekeepers. If communication with the primary gatekeeper is lost, the
RealPresence Group system registers with the alternate gatekeeper but continues
to poll the primary gatekeeper. If the system reestablishes communications with the
primary gatekeeper, the RealPresence Group system unregisters from the
alternate gatekeeper and reregisters with the primary gatekeeper.
Note: No multipoint on Group 300 and 310 systems
Polycom RealPresence Group 300 and 310 systems cannot be enabled for multipoint calling.
