My * waits a second or two before giving a message for echotraining / line stabilization. Not quite sure how easy it would be, but if you looked at the speech pattern, a typical human is going to say a word or two, then have silence. An answering machine generally has an exteneded time period of speech before silence. This is not universally true - I know some people who just have a simple "Hi, leave a message. (beep)" message. That's short enough to break the algorithm. Of course then you have the residential versus business way of answering a call. "Dr Tweedle Dum's office, this is Sherry speaking. How can I help you today?" Answering machines are a big problem for all computer calling systems. Sears, JC Penney, and the local doctors office all have proven to me that they can't even handle a simple answering machine. I can't believe that anyone could come up with a fool-proof system. Heck, the big companies can't seem to do it at all. _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
