I've a problem with an IP Phone which doesn't dial. For example, when I composed a 4-digit number, I hear the beep but phone doesn't dial. The phone wait other digit and communication isn't establish.
And the more strange, when I change the directory number, the phone dial but when I put the original directory number, the phone doesn't dial.
I don't understand why ? I reset phone, erase and recreate configuration of my phone but nothing.
Does someone has already meet this problem?
P.S. I've a call manager 4.2(3)
