asterisk users - May 2004 - tying a call to indications/call progress tones

i am trying to make an automated outbound call playing a message upon answer but
i am having trouble triggering the message except with a timer (not paying
attention to call progress tones or indications)

have the call working via php agi, just not sure how to deal with the call
progress/indications stuff.

Help?  Thanks in advance.
