<br><br>exten => something,priority,NoOp(${AGI(program|args)})<br><br>look at 'core show applications' and 'core show functions' to see what you can call in each case. Applications and functions aren't interchangeable.
<br><br>If you want to use an AGI script to set a variable you can later use as an arg to Dial(), then you want to call the AGI application from your dialplan, then from inside the AGI script do your calculations and issue the AGI command "SET VARIABLE name value".
<br><br>So if you have a very basic AGI script that just does this:<br><br>echo "SET VARIABLE foo bar"<br><br>then your dialplan could look something like this:<br><br>exten => foo,1,AGI(foo.agi)<br>exten => foo,n,NoOp(${foo})
<br><br>And you'd expect to see "NoOp(bar)" on your console when you called that extension.<br><br>Of course, you'd want to use one of the available AGI frameworks to do the heavy lifting of parsing the input that Asterisk gives an AGI script and take care of the error handing when you issue a command back to Asterisk from the AGI script.
