Sunny day
The first set of call flows are for sunny day. This is when all SIP endpoints have full connectivity
across the WAN back to the core and are registered to the Session Manager. All SIP trunks
are in service.
Internal call
1 Store Phone originates call to a corporate station 1014553.
2 SM sends 1014553 to CM for origination processing.
3 CM identifies call as internal and routes 1014553 back to SM.
4 SM sends call to destination phone [phone] at destination CM.
This call flow is similar for calls within the same branch or calls to other branches with
the exception that the calls terminate at the destined branch.
A RTP Media stream is initially between the Store Phone and a CM-1 media gateway.
This will shuffle between the Store Phone and CM-2 or another endpoint once
established.
