The Cisco IP Phone in Cluster 1 makes a call to the Cisco IP Phone in Cluster 2. Intercluster Cisco CallManager communication takes place using the H.323 Version 2 protocol. A Cisco IOS Gatekeeper also serves for admission control.
The Cisco IP Phone can connect to the Cisco CallManager via Skinny Station protocol, and the Cisco CallManager can connect with the Cisco IOS Gatekeeper by using the H.323 Registration, Admission, and Status (RAS) protocol. The admission request message (ARQ) gets sent to the Cisco IOS Gatekeeper, which sends the admission confirmed message (ACF) after making sure the intercluster call can be made using H.323 version 2 protocol. Once this happens, the audio path gets made by using the RTP protocol between Cisco IP Phones in different clusters.
