[asterisk-dev] segmentation fault

[jonathan augenstine]

Russell,

Basically what I am trying to do is to play my own music on hold to callers
waiting in a queue.  During that call I want to be able to collect DTMF from
the caller so that I can change audio files that I am playing back to the
caller.
