Client has 20 extensions and 5 lines.Only Extensions 221 (recp w/m7324 & cap) and 222 (T7316e)have the 5 lines appr/ring on them. AA is set to pickup after 4 rings at any time of the day. When 222 forwards her telephone to vm at the end of the day instead of the aa picking up after 4 rings it goes directly to 222 vm. Please help.
