Hi, Our customer has different requirements for the situation where a person answered a call or a answerphone. I found a solution on: http://wiki.freeswitch.org/wiki/Freeswitch_IVR_Originate#Answer_confirmation This solution requires a person to press a DTMF. However, I'd much rather do it the other way round, but didn't find anything when searching. I heard mentioned 'wait for silence', but I don't see how waiting for silence will give me information on human VS machine detection. Any ideas or solutions out there? Our implementation is done in Javascript, so ideally the solution should be tied in.
