Hi I have setup an outbound conference which ends automaticly if the initiator leaves thanks to the "endconf" flag. Now I got an new requirement: The called participants shold not automaticly join the conference, but instead the system should first play an audio file like "this is a conference call, press 9 to enter", and only after pressing "9" they should be added to the conference. I solved this (mostly) with "execute_on_answer" and a lua script: --- repeat digits = session:playAndGetDigits(1, 1, 3, 3000, "#", "audio.wav", "", "[9]") until digits == "9" --- The only problem is now that when the initiator hangs up while this script is running the call/conference doesn't end. In my tests the call continued like nothing happend, and after pressing "9" the participant was still redirect to the conference where he was now the only member. Any ideas how to solve this? Thanks.
