the voice mail box is not checked .
The strange thing is that when the phone signat that is forward to a directory number i can not see the number on the web page of the call manager .
With another type of phone ( 7965) i see on the call manager web page the same directory number that i see on the screen of the ip phone .
When I try to call the directory number of the 3911 that is forward to another ip phone i can hear the ringing tone for a few seconds , but after that the call is interrupted and i get an alert that told me that the number does not exist .
Do you need the trace of the call manager ?
thanks a lot
