[Asterisk-Users] How to detect answering machine
Hi! Does anyone of you have an idea how to detect an answering machine on a dialout call? I am working an a voicemail system wich calls the subscriber but I don't want to fill their answering machine. Maybe I could detect somehow if there is incoming voice when playing the message. usually real persons don't talk when they listen but answeringmachines do. ;-) Thanks in advance, Chris ___ 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

Just start off with "Please confirm by pressing #" before getting too chatty. Then quietly wait five seconds -- if the other end doesn't dial #, hang up. If there's an answering machine, it shouldn't record anything. > -Original Message- > From: Christian Victor [mailto:[EMAIL PROTECTED] > Sent: Friday, August 13, 2004 11:47 AM > To: [EMAIL PROTECTED] > Subject: [Asterisk-Users] How to detect answering machine > > > Hi! > > Does anyone of you have an idea how to detect an answering > machine on a > dialout call? > > I am working an a voicemail system wich calls the subscriber > but I don't > want to fill their answering machine. > > Maybe I could detect somehow if there is incoming voice when > playing the > message. usually real persons don't talk when they listen but > answeringmachines do. ;-) > > Thanks in advance, > Chris ___ 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

I have thought of timing the amount of silence there is at the start of a call, as an answering machine will usually start speaking as soon as the call is picked up. There would probably be a brief silence when a human picks up a handset. This would probably require a bit of work though. Brian.

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
