I am looking for a solution for our network of GSM run PA speakers. I have tryed the .call files in /outhoing/ and that works fine but not for what I need. I need to be able to call several phones at the same time, and then connect the ones that has answered together to play the same sound file to all of them at the same time.
I need to be able to load the numbers and soundfiles dynamicly, and not through a static dialplan.
Is there any good way to do this in Asterisk or should I do this from a softphone solution instead?
All ideas are welcome
