Can not make Outgoing Calls using 7911 IP phones..
I have 2821 Communication manager express with 6 Nos. 7942G IP Phones & 10 Nos. 7911 IP Phones in network.
Everything working fine. But, Once every 2 months, i am getting problem with couple of 7911 IP Phones that it can receive incoming calls, But CAN NOT MAKE OUTGOING CALLS.
In order to resolve this problem, I am creating new ephone-dn directory number and assinging same ephone-dn to specified ephone number. & removing old ephone-dn directory number for same. Then those particular 7911 IP Phones can make outgoing calls.
and i have to reset those IP PHones & have to reconfigure it.
Is there any specific solution or troubleshooting for this kind of problem???

the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
