Description
If the RMX 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 RMX prefix.
In such cases this System Flag should be set to NO.
Default: YES
Enables or disables H.323 index timer according to standard or proprietary
H.323 protocol.
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 RMX is configured to accept calls from both
Microsoft LYNC and Cisco CUCM as CUCM requires the Contact
Header.
