[SOLVED ]SX10 TC7.3 no audio and Video when calling

[reigo.rannak]

Hi,

I have very wierd issue with one sx10(TC7.3.0) endpoint. When I make a call to another sx10 (TC7.1.4) then signalling works fine and call is connected but there is no audio and video.It is not working even when I call to some external different type video endpoint. I noticed that there is no receiving info about audio and video but transmit codecs and other info looks correct. 

Hope someone can help me to troubleshoot the problem.

More info about my solution:

I use CUCM with VCS-c and VCS-E. All endpoints are registered to CUCM. I have 16 SX10 endpoint with TC7.1.4 and one TC7,3,0. I think upgrading all endpoint to TC7.3.0 is not the solution because there are problems also with all other types enpoints.

Hi I have this problem too.

Do you have any firewall in between end point and VCS-C? I managed to solve it by allowing firewall rule from VCS-C to End point.

Yes, Actually the problem was firewall rule! 

The main problem was that these two endpoints didnt saw each other. ( Ping - Packet loss )

Signalling was working fine because both of them got ping CUCM but not each other :)

So problem is solved.

Thanks.
