We've succesfully connected an Asterisk PBX to a Panasonic Hybrid Phone System. The Asterisk server uses the AVM Fritz PCI card to make the connection. When we make a call through the Asterisk server to a phone that is connected to the Panasonic phone system and the receiving end tries to transfer the call to another phone (also connected to the Panasonic), we get a busy tone. Any ideas to solve this problem?
Thx.
