Answer:

Explanation:

The H.323 setup is suspended before the destination phone, triggered by the H.225 alerting
message, starts ringing. The RSVP reservation is made in both directions because a voice call
requires a two-way speech path and therefore bandwidth in both directions. The terminating
gateway ultimately makes the CAC decision based on whether or not both reservations succeed.
At that point the H.323 state machine continues either with an H.225 Alerting/Connect (the call is
allowed and proceeds), or with an H.225 Reject/Release (call is denied). The RSVP reservation is
in place by the time the destination phone starts ringing and the caller hears ringback.
