The SIP routing system uses the Routing Profile field within the Server Flow PSTN-Trunk to take routing decisions. The routing profile resolved is To-CCE-ASM. The system uses the Next Hop Address fields within the To-CCE-ASM profile to locate the SIP server and the outbound transport is selected to TLS as provisioned.

As the Next Hop Address fields are configured with an IP Address, the system tries to find a matching Server Configuration for that IP address. The system finds a matching Server Configuration CCEASM to route the call towards CCE-ASM server.

As the call is being routed towards a server, the routing system tries to find a matching server flow as part of the outbound call processing.
