I want to make an outgoing call to a PSTN number and when the call is answered, play a file with a message.

I’m using asterisk 1.2.13

Anybody know how can I do this???

Thanks in advance

create a .call file that has the PSTN number call an extension on your server. for that extension, create a dialplan that when the extension is called, it answers, plays the message and hangs up.

Could you please give me an example of the .call file and where must be created please??
Additionally … how must the dialplan looks like??

Thank in advance
