Use this parameter to support local authentication autonomously on a per-IP trunk group basis in situations where an IP-PBX does not perform a registration and the service provider does not require/want registrations (refer to IP Trunk Group Authentication for additional feature functionality).

Info
titleNote

 If the IP Trunk Group (IPTG) authentication is configured for both ingress IPTG sipTrunkGroup and ingress IP Peer, the IP Peer configuration takes will take precedence.

If you wish to use the intChallengeResponse and incInternalCredentials flags configured solely on IPTG, the IP Peer must not be present in the configurations. Otherwise, the IP Peer flags default to 'disabled' state and take precedence over IPTG flags. the sipTrunkGroup level, the IP addresses of the IP Peers from which SBC receives SIP messages from must not match any IP address of the configured IP peers in the ingress signaling zone. If the source IP address of received SIP messages match an IP address of any IP Peer in the signaling zone, the intChallengeResponse and incInternalCredentials flags on the ipPeer level will take precedence.
