Domain (Station) Control — Third Party Merge
This scenario shows the call flow for a Third Party Merge capability. Station 4567, 
after disconnecting from the active call (call_id=45), reconnects to the held call 
and transfers the call (call_id=78) to station 4569 (see Figure B-21).
This scenario is a continuation of the scenario shown in Figure B-19.

Domain Control — Call Disconnects
This scenario shows several call drops and/or disconnects for Domain Control 
stations (see Figure B-23). The call at station 4569 is dropped via a
Third_Party_Selective_Drop request issued by the Domain Control association 
for station 4569. The held call at station 4568 is dropped by the held endpoint. The 
active call at station 4568 is dropped via a Third_Party_Selective_Drop request 
issued over a Call...

8. Call Redirection
This section presents several scenarios for call redirection (for example, 
Coverage, Call Forwarding, Send All Calls or ASAI Redirect Alerting Call).
Incoming Call to Station Forwards to Another 
Station
This scenario shows the call flow for a call from station 3568 to station 3569 (see 
Figure B-24). Station 3569 has call forwarding active to station 6055. Station 6055 
answers the call.
