Hi.

Please help me in getting the port numbers used by Polycom Video Conferencing Endpoints during VC.

Also I need to know specific port which can block video conferencing session between two end points.

Thanks in advance.

You should be asking Polycom this question; however, here's a generic answer. Audio/video media uses RTP which has a vast UDP port range (Cisco's is 16384 through 32767). If Polycom uses the same range you can block it through an ACL; however, it will break both audio and video media.
