[VoIP] Continuous music on hold?

[Jayson Smith]

Hi,

     I'm wanting to implement a continuously running music on hold. What I
mean is this. In a traditional Asterisk MOH, when the last person connected
to the MOH hangs up, the music stops, and doesn't continue until someone
else gets put on hold. In other words, if you hang up on an MOH and call
right back, no music or audio will have passed between the time the call was
disconnected and when you connected again. I'd like to have a continuously
running MOH, which runs even with nobody connected to it. This would allow
for the implementation of a certain style of centralized drum recording
machines from back in the day before I was born, where when you were
connected to the recording, it just dropped you on the recording at whatever
point it happened to be, and the recording was running all the time, even
with nobody connected. Therefore, you never knew where you were going to
come in on any given call. I've thought of having something dial an MOH
context and just keep the connection up. However, is there any way for
Asterisk to dial into something within itself when nobody real is actually
making a call?
Thanks.
Jayson
