Hello, I haven't seen any recent posts on call progress detection, so here's a question: How would one accomplish an automated outbound dialing application using *, whereby a requirement is to wait for the greeting to complete (live person, answering machine, voicemail) before delivering the message? For example, playing a 'reminder' message to a list of recipients. I know its possible using telephony boards (ie. Dialogic/Intel), but don't know about *. I have experimented with callprogress=yes in zapata.conf, but not sure if that was intended to cover what i describe above. Regards, Steve

What you need is something like a ecording looking for silence post answer. AGI supports record with silence detection. Once you detect the specified amount of silence, you can play your message. -- Steven Critchfield <critch@basesys.com>
We have done some answering detecection coding that can differentiate answering machines and live answers. We're having problems with operator intercepts. Asterisk is showing them as No Answers, Does anyone have any suggestions on how to properly differentiate between Operator Intercepts and No Answers in the call progress detection?
