Explanation:

Here is how the call is established with RSVF-based Call Admission Control

1) The Cisco Unified Communications Manager (at the left-side) sends an H.225 setup to the Cisco UBE.
2) The Cisco UBE processes the call setup information and associates an outbound VoIP dial peer requiring an RSVP reservation. The Cisco UBE sends out an RSVP Reservation request to the remote Cisco UBE.
3) The remote Cisco UBE acknowledges the reservation and initiates the reservation for the return path, which is acknowledged by the local Cisco UBE.
4) The H.225 setup message is routed to the remote Cisco UBE, which then routes the call to the outbound VoIP dial peer pointing to Cisco Unified Communications Manager (at the right-side).
5) H.245 negotiation occurs with media flow-through enabled.
6) The call is established.
