hello all, i have now encountered this issue 2x in 2 seperate customer environments. the promlem i am having is getting video to pass between CUCM and VCS when CUCM is on version 7.1.5. i have built a sip trunk according to the Cisco config guide (doc # D14602.09). right now if i place the call from the C40 as H323 to the 8941 i get video and audio both ways. if i reverse the same call flow i get audio only. if i place a SIP call i get signaling only (no audio/video). this works like a champ on CUCM 8. what am i missing here? i have SRTP, and retry video as audio boxes checked and MTP disabled. i have set the max per call bandwidth on the VCS to 384k for calls to/from CUCM. i have tried using the CCM built in MTP and i get audio only at that point. what could i possibly be missing?
Good call flow: C40 (h.323 protocol running TC4.1.x )-> VCSC (X7.1) -> SIP Trunk -> CUCM (7.1.5) -> 8941 IP phone
everything else fails
