I want to implement a “raise hand” functionality in ConfBridge by using dialplan_exec in a menu. I’ve Originated a call to a local channel, with ChanSpy Whisper, and bridged that to an extension, that should playback an audio file that says “Question from”, then say the last 2 digits of the users caller ID. It works with one problem:
Playing back the WAV file “Question from” is at about half speed and very garbled, but SayDigits plays just fine. The audio file is a standard 16-bit PCM WAV, created using Record(). Playing it back any other place in the dialplan doesn’t exhibit this behavior… It’s only when playing back using ChanSpy to the channel.
