Hello, I've got a voip lab at home with a Cisco Call Manager Express and I've just downloaded 3CX. I've got a couple of phones registered via Skinny to the call manager. I've also got a couple of SIP phones registered to the 3CX box. The problem I've got is to get the call manager and the 3CX to pass calls to each other. I've configured a dial peer using sip on the call manager but I get nothing. They can ping each other no problem so its not a connectivity issue. The phones can call to each other on the same device so they are registering ok as far as I can tell. Thanks :?
