I got a problem on my network, I opened all the ports required bycisco jabber on my ISA 2003 firewall , the users are able to login , they also able to dial ,
the problem is that they don't receive video nor audio neither they send video or audio to the other side.
When they connect to a generic WIFI router , they recieve audio and video, and they are able to make calls
Any suggestion what I have done wrong.
