I wanted to generate a call from a script, and deliver a voice message, through a DAHDI channel, to a pots line.
This class does it, it tells you in the end if the line was busy, if it was never answered or if the call succeeded.
This is, if you trust dahdi callprogress, which is really broken… this example works better for SIP calls.
