Set parameter to "3GPP" to select GIBA security mechanism when a REGISTER message is received without specific security headers. The SBC validates Source IP Address against Via header IP Address and transparently passes UEs Via header in egress messages towards network entities. If REGISTER message is received with "sec-agree" in Proxy-Require header along with Auth headers, and no IP Sec profile is configured, the SBC rejects the message with "4xx Bad Extension" error response irrespective of the Access Class parameter value.

When GIBA security mechanism is selected and Via header is configured to pass transparently to egress leg, SBC inserts a “received” parameter with the source IP address of the PDU if the host portion of the UE’s Via header does not equate to the source IP address seen by the SBC.

Possible choices:

• 3GPP – Select to enable GIBA security mechanism as explained above.
• none – (default) SBC defaults to SIP Digest without TLS authentication.

• required-group  – If this option is selected for an ingress IP trunk group in relation to a received call (e.g. call from IP-PBX towards AS) so that if the source IP address and port of the INVITE/OOD request do not match the source IP address and port of an existing registration in the zone, they are rejected. However, if the AOR does not match, but if the source IP Address and the port match to the existing registration in the zone, messages are accepted. If this option is selected for an egress IP trunk group in relation to a received call (e.g. call from AS towards IP-PBX), the user part check between registered AoR and Request-URI of the INVITE does not occur, and the call is accepted.
• required-group-nonpriority – Use this option to prevent unregistered IADs from making or receiving non-priority calls. All emergency calls are allowed even if the source IP/port fails to fetch RCB.

Inside Expires
Minimum

This controls the initial expires value in a REGISTER relayed to a registrar. Specify time in seconds. Default is 3600 seconds.

Since the SBC expects an expires value greater than 540 seconds (9 minutes) from the registrar, do not set “insideExpiresMinimum” value less than 540 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”.
