We have a Cisco Call manager 6.1.x.x.x running, I have Polycom Soundstation IP 7000 registered with the call manager. I can make calls outside calls and internal calls to the phone work fine (External to the phone work too). However when I make a call from the polycom to another internal cisco phone the other side rings the user picks up but neither side can hear each other.
Anyone come accross this issue?
