What ports need to be opened in firewall for IPVIDEOTALK?



What ports need to be opened for full functionality of IPVIDEOTALK?

I can get the video at the moment, however, I have never been able to get audio on any IPVIDEOTALK conference.

Any response on this would be extremely helpful…


By default the mic is muted on entry. May be this is the case.

There need no firewall ports to open as its internet based.
