Hi ,
At one of my client place i have Cisco Call Manager 4.2 (3) and 7941 Ip Phones and 7912 Ip Phones , 7985 video IP Phones and 2800 Voice Gate way.
Now the Problem is Im Not able to Dial to any External Phones even to an External Mobile no or a Land Phone , how ever i am able to dial all internal Ip Phones from this 7985 Ip Phone .
All other models of Ip Phones are working properly .
What may be the Cause ??
