I can see the correct calling party number on the display of my 7940G. But if calls are not answered, under 'missed calls' i see only "unknown number from external call" records. Why is the number not logged?
We have a 1760-V with 12.3(11)T3 and using a single BRI interface (VIC-2BRI-NT/TE) to connect to the PSTN.
Thank's for any help.
