Direct inbound call to OC client, OC client answers
This scenario as illustrated in Figure 97 "Outbound call from OC client to
another client, phone answers" (page 243) depicts the prevention of dual
forking in a configuration where both users are registered to the same
Communication Server 1000 with the presence of SPS. Joe calls Bob from
his OC client. Bob accepts the call from his phone.
ATTENTION
In this call flow scenario, homing operation is performed on the Communication
Server 1000 to validate the caller’s (Joe) permissions before proceeding with
the call.
