I have 2 Avaya B179 Conference Phones with the same issue... Both phones cannot make or receive calls... The only thing I did was unplug them move a table around in the office a bit and plug them back in.... Both phones do not show any error when booting up and when I try to make a call from the phone I hear a long beep tone when calling a number "this is normal... sounds like its ringing the person on the other end except for the other person never gets the call"... I logged into the web interface on one of the phones and noticed that the phone shows Status: Not Registered
I factory reset one of the phones and entered in the User/setup info and get the same issue...
All help would be much appreciated
