Forgive me if this is a subject thats been talked about before, but I could not find any answers. I'm setting up my first UC540, using CCA 3.1.1. All seems to go fine. I have no POTS, and my SIP truck is working... except it rings busy if I call in with the inbound setup to go to the auto attendant. It will work if I send incoming calls to a specific extension.
