Telephony Gateway and Services call flow
This section explores dual forking call flows in different scenarios when
Mediation Server is present.
This scenario as illustrated in Figure 94 "Inbound call to OC client with SPS,
OC client answers" (page 240) depicts a configuration of a UDP dialing
plan on the Communication Server 1000 and the presence of an SPS
component on the network. A Communication Server 1000 user dials 5555
which is the phone belonging to user Bob in the demo.com domain. Bob
accepts the call from his OC client.
Note: This scenario would also apply if the inbound call originated from
the PSTN.
