I have a Q.SIG link from a Call Manager to another PBX, and I was wondering if there is anyway to do shared lines over it. For example I want to have an Extension on my Cisco phone and the same extension on the PBX. I tried to setup a fake Cisco phone and do a forward all to the PBX phone, which works of you call the fake ext directly. I then put both the Cisco Extension and Fake Extension in a Hunt group but that does not work, it rings once on the Cisco phone then I get a fast busy. If anyone has any other Ideas please let me know.
