Hi guys,

We have got a strange problem at one of our customers so I wonder if anybody has seen this before and might know how to fix it. We have got MeetingPlace 7 connected to CUCM 7 via a SIP trunk. The CUCM 7 has got H.323, SCCP and SIP video clients connected to it. Also it is connected to a CCM 4.2 with H.323 gatekeeper controlled trunk. This CCM 4.2 has got H.323 and SCCP video clients on it. We are making test video calls and have the following results:

Direct call from H.323 client on CUCM 4.2 to H.323 client on CUCM 7 and back - everything is all right;

Direct call from H.323 client on CUCM 4.2 to SCCP client on CUCM 7 and back - everything is all right;

Direct call from H.323 client on CUCM 4.2 to SIP client on CUCM 7 and back - everything is all right;

Call from SCCP client on CUCM 4.2 to SCCP client on CUCM 7 through MeetingPlace - everything is all right;

Call from SCCP client on CUCM 4.2 to SIP client on CUCM 7 through MeetingPlace - everything is all right;

Call from H.323 client on CUCM 7 to SCCP client on CUCM 7 through MeetingPlace - everything is all right;

Call from H.323 client on CUCM 4.2 to SIP client on CUCM 7 through MeetingPlace - everything is all right;

Call from H.323 client on CUCM 4.2 to SCCP client on CUCM 7 through MeetingPlace - no video.

Any idea what it might be??? Thanks!
