MC 3100 communication call flows
This chapter describes the call flows for typical communication scenarios
between the various components of the Mobile Communication 3100
(MC 3100) and the communication server. These scenarios identify the
messages that the components exchange.

The MCG 3100 registers with the Network Routing Service-SIP Proxy
Server (NRS-SPS) as a SIP gateway.
In the NRS-SPS database, the NRS-SPS defines the MCG 3100 as a
dynamic endpoint and assigns it an endpoint name.
In the redundant MCG 3100 deployment, the NRS-SPS configuration
represents both the primary and secondary MCG 3100 as a single
Gateway Endpoint (GW EP). The NRS-SPS can only register one
MCG 3100 (the active one) at any point in time, so the registered
MCG 3100 receives all related SIP traffic.
