[asterisk-users] AGI: blocking script until playback complete

[Chris Bagnall]

Greetings list,

I've done AGI scripting before, but in the past I've always wanted 
control to be returned to the dialplan as soon as possible.

However, today I have a scenario where I want the script to remain 
running during the playback of a file so that I can read DTMF at the end 
of playback. However, doing this:

GET DATA en_welcome 5000 6

Results (correctly) in the following in the asterisk console:
     -- <SIP/a.b.c.d-dc027b50> Playing 'en_welcome' (language 'en')

But the AGI continues to run on after this point, not waiting for either 
the sound file to be played, nor for the expected 6 DTMF digits.

Adding a simple 10 second sleep/wait to the AGI allows the sound file to 
be successfully played back.

I'm sure I must be missing something very obvious, buy my google-fu is 
failing me this afternoon.

Suggestions gratefully received :-)

Thanks in advance.

Kind regards,

Chris
