Polycom, Inc.
Description
When set to YES enables endpoints that support People+Content and
require a different signaling (for example, FX endpoints) to receive Content.
Default value: NO
Possible value: YES/NO
For use in the Avaya Environment.
In the Avaya Environment, set the flag to YES to ensure that H.245 is
tunneled through H.225. Both H.245 and H.225 will use the same signaling
port.
Default value: NO
Possible value: YES/NO
If the RealPresence Collaboration Server is configured for IPv4 & IPv6
addressing, RAS (Registration, Admission, and Status) messages are sent
in both IPv4 and IPv6 format. If the gatekeeper cannot operate in IPv6
addressing mode, registration fails and endpoints cannot connect using the
RealPresence Collaboration Server prefix.
In such cases, set this system flag to NO.
Default value: YES
Possible value: YES/NO
Enables or disables H.323 index timer according to standard or proprietary
H.323 protocol.
Default value: 0
Possible values:
• 0 (Default) - Sets the H.323 index timer to Polycom proprietary.
• 1 - Sets the H.323 index timer based on the H.323 Standard
recommendation.
Note: For homologation and certification testing, this flag must be set to 1.
When the flag value is set to:
• YES - The Contact Header is removed from the UPDATE message that
is sent periodically to the endpoints.
This is required when the SIP Server Type field of the IP Network
Service is set as Microsoft. Removal of the Contact Header from the
UPDATE message is required specifically by OCS R2.
• NO - The Contact Header is included in the UPDATE message. This is
the system behavior when the SIP Server Type is set as Generic.
This is required when the RealPresence Collaboration Server is
configured to accept calls from both Microsoft Lync and Cisco CUCM as
CUCM requires the Contact Header.
Possible values: YES/NO
