Calls from outside cannot press “0” in a users voicemail and get to the AA. When I call the AA from an inside extension and got to someone's Voicemail, ie: 214 the call transfers and I can "0" out to the AA. I have all the voicemail set to forward back to the AA when zero is pressed. It works from inside, but not from outside. Callers also can't retrieve voicemail by calling the AA from outside. The cue does not hear the dtmf tones. I have employees with voicemail setup to call a separate number which goes directly to the voicemail retrieval system. I had an open TAC support case some months ago, but no solution was working and I put it on the back burner for awhile. Now I need to solve this issue.
