Hi,

You can try to use MusicOnHold() application to do this. However docs
don't say how to terminate it. I presume that Playback(silence/1)
would stop it, you're welcome to try it out :) That should be better
solution than creating child channel etc.

Also, i'm curious what kind of "massive processing" you need in
dialplan? It's best practice to don't do anything that may delay call
for long, as caller can get bored/angry etc.

If you just have to do something heavy for each call and you don't use
result of that operation to determine next step of call, you can do:

System((/usr/bin/do-something.sh)&)

note, the ampersand after first brackets will make to run shell
command in background.

If you need the result of some operation to send call further, you
should optimize that as much as possible by creating some kind of
cache.

Also, there's a trick - you can launch background shell command at
beginning of call, then send customer to IVR or even Dial() and at
later point check results. For example you can add G or M argument to
Dial() to execute part of dialplan macro/gosub upon answer.

Hope that my explanation helps :)

Regards,
Atis
