Cannot connect to make a call or receive one on my handsets. My handsets show they are working normally but I can't make or receive any calls. I have tried to call and receive calls from 1-303-330-1766 (my cell phone which worked two days ago). I have tried to call several numbers including 1-866-507-0026 and 1-303-423-0924.
On-line I was able to receive a call from my cell phone. The problem seems to be only with the handsets. They both show logged on and on-line which apears normal except no calls get in or out from them.
