3 bad modules. The first one died as a result of a thunderstorm, the first replacement had a 30 second lag time between vm prompts, the second replacement didn't have the lag time between promts and let me enable outcalling but any greetings and A.A.'s I recorded played back as dead air. The handset was fine and when I reviewed and accepted the recordings they played back normally, but when you called into the A.A. or mailboxes no dice. Just a few seconds of silence and then the time-out kicked in. Messages left in the mailboxes from outside registered as new and had the time and date stamp but no audio. Picked up a fourth module from a different supplier today, did a restore and everything works fine. Needless to say someone lost all of my future business.
