Use this flag to specify the type of endpoint registration validation required.
Require Registration flag to ‘supported-group’ for the IP Peer on which surrogate registration functionality is being enabled.
| The time (in seconds) a SIP endpoint's registration session lasts before requiring re-registration. This value does not apply if the endpoint is NAT'd. The value ranges from 15 to 65535 and the default value is 3600.|
Inside Expires Minimum
Controls the initial expire value (in seconds) in a REGISTER relayed to a registrar. The value ranges from 0 to 65535 and the default value is 3600.
- Since the SBC expects an expires value greater than 480 seconds (8 minutes) from the registrar, do not set “insideExpiresMinimum” value less than 480 seconds. Ideally, set this value much higher (3600 seconds is recommended) to avoid overloading registrar with register refreshes.
- When configuring surrogate registration, be sure to set the expires value of ingress trunk group toward IAD to the maximum default value of “3600”.
Include XOriginal Addr
Enable this flag to insert the X Original Addr header into REGISTER message.
Bulk Register Format
Use this flag to determine how the registration requests are formatted with respect to RFC 6140.
disabled (default) – REGISTER message is not formatted as per RFC 6140.
enabled – REGISTER message is formatted as per RFC 6140.
followIngress – No changes are made to the Egress Register with respect to RFC 6140.
