The routing system uses the URI Group and SIP Received Interface fields of the Server Flow configuration as additional matching criteria to determine a server flow match.
The SIP routing system uses the SIP To header URI of the incoming request for comparison with the provisioned URI Group to decide a match. If URI Group matches, the SIP routing system validates whether the destination IP address of the incoming SIP request matches the provisioned IP Address field of the Received Interface configuration . If either of the URI Group or Received Interface fields do not match the SIP routing, the routing system skips to the next server flow. It scans the set of server flows associated with the server configuration for a match.
Note:
The URI group can be a wild card entry (*) that can match any SIP request.
The Received Interface field contains the IP Address of the Interface on which Avaya SBC received the SIP request from the network.
If a matching server flow is found, the system continues with outbound call processing.
If no matching server flow is found, the SIP routing system rejects the call becausean outbound server flow is not configured.
