[Freeswitch-users] voicemail_greeting_number stickiness

Hello all, I'm trying to set up our voice mail system so that greetings can be mapped to failure conditions, ie. "I'm in my office, but not taking calls" when a phone is busy or in DND mode, but "Sorry I'm not here" if no_answer. I programmed things to set voicemail_greeting_number in the dialplan based on the bridge failure cause set when we rang the phone, but when I execute the voicemail application, it stores that greeting number in the database. I would much rather override for this call only, so that the user can still take advantage of the voicemail application's option to select a greeting. (which would be used as the no answer greeting under normal circumstances). Any thoughts? -Tim
