[asterisk-users] Playing sound while talking

[Artifex Maximus]

Hello!

Is it possible play background sounds while talking?

I would like to make an outgoing campaign with the possibility playing
sounds in background by command. But the extra is I would like to
choose which sound to be played. In short operator calls a number,
talking to callee and sometimes play different sound (for example
different music) in background which should be interruptible and then
ask questions from callee. Is it possible? If yes from which version
number? I have an "old" 1.2 system at this time. I am using Asterisk
1.2.10 on Fedora Core 4 now. Looking for plain Asterisk solution and
no commercial offers please.

Any idea is welcome. Thanks in advance.

bye,
a
