[asterisk-users] How to get Asterisk to make batch calls?

[Leo Burd]

Hello there,

I'm currently building a PHP-based software to help users make batch 
calls.  Basically, users provide a script and list of phone numbers.  
The system calls those numbers and plays the script to whoever picks up 
the phone.

Currently, the system does one call at a time via direct access to the 
Asterisk Manager Interface, but does not seem to be very efficient.  
Ideally, I'd like to be able to run calls in parallel.  What is the best 
way of doing that?  Would I need to use some sort of proxy?  Is this 
something that I should try to implement with AJAM?  If possible, would 
anyone point me to code samples that might helpful to me?

Thanks in advance,

Leo
