Since yesterday, we have a phone that can no longer call. The phone find his configuration (number, location, calling search space ... etc. ...), can receive calls (Internal and external) but but when I want to dial a number, I hear numbers and then nothing, no tonality.
I try to reset the phone, shutdown phone, erase and recreate the line, Release DHCP address on the phone.
An idea ?
P.S. I've call manager 4.2(3)
