[asterisk-users] Asynchronous AGI Problems (Asterisk 1.8.7.0), ubuntu-server

[Mehmet Avcioglu]

Actually it doesn't say "AGI(async:script)" it says "AGI(async:agi)" and than continues further to setting up an AMI user so the script is executed through the manager interface?? Than it says "AGI(agi:async)".?? Well most importantly it says "Cons of async AGI: It is the most complex method of using AGI to implement." ..:) I have been interested in Async AGI as well and after reading your post looked into the link you provided, seems different than what we immediately think, a background process.

Perhaps just start the script normally "AGI(script.sh)" and than inside it run your background process "background-script.sh > /dev/null 2>&1 < /dev/null &" or fork a new process, detach, run in background, etc...

Hopefully somebody else can point us towards the right direction in setting up a real asterisk asynchronous AGI application.
