| Parameter | Description |
|---|
Int Challenge Response | Enable this flag on the ingress IP Peer to allow the SBC to reply to local authentication challenges autonomously. If this flag is disabled, the SBC will not reply to authentication challenges locally even if credentials are configured on the egress IPTG. The options are: disabled (default)enabled
|
Inc Internal Credentials | Enable this flag on the ingress IP Peer to allow egress IPTG authentication to be internally created using the authorization information in mid-dialogue without being challenged. The options are: disabled (default)enabled
| Note |
|---|
If Int Challenge Response is disabled, Inc Internal Credentials is not used. |

If 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 flagsthe sipTrunkGroup level, IP addresses of the IP Peers 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. |
