does any one know what router ports need to be open for an ip phones on different vlans to talk both ways i get one way audio .

I think it's UDP 50000-50511, same as from a phone to a MiVB, but it should be in the Engineering Gudelines. Or just open up UDP above 20,000 which will cover SIP ports as well.

The engineering guidelines say the UDP source ports 1024-65535 to dest ports 20000-30999
