I am confused how the rtp stream flow between the two end point belongs to two different CCM cluster.
IP Phone A --CCM1--GK--CCM2--IP Phone B
In this case how will be the rtp stream flow between the two ip phones?
Will it be from IP Phone A to CCM1 and CCM1 to CCM2 and from CCM2 to IP Phone B and vice versa ?
or
IP Phone A to directly IP Phone B ?
Thanks

RTP is between endpoints

If you're ever curious about this sort of thing you can go to the webpage of the phone while it's on the call, and go to stream statistics. It will tell you the remote IP and port for the current call, and it will show the remote IP phone.

Yes, it's directly between the endpoints (phones). It may be helpful to keep in mind that GateKeeper functionality is primarily Registration Admission and Status (RAS). When a call is initiated from a Registered endpoint within the originating CM cluster, a Admission request is made to the GateKeeper for inter-cluster calls. The GateKeeper then verifies Status of the called endpoint on the called CM cluster. If sufficient bandwidth is available for the call, the GateKeeper signals both CM clusters to begin the call setup between the two endpoints directly.

Thanks. Then in this case MTP will not be used. Correct ?
Still i want to clarify one more thing. Let say if we configure as IP trunk ( h225 controlled or SIP)between two CCM or CCM and other IP PBX, then how will be the rtp stream between the two IP Phone registed to different CCM or IP PBX ?
