[arm-allstar] agi vs allstar -rx commands

[Lowell]

Doug:

I believe your version 1.5 is based on Asterisk 14.

A list of AGI commands can be found here ( I understand it is an API but
the web page calls them AGI commands).:

https://wiki.asterisk.org/wiki/display/AST/Asterisk+14+AGI+Commands

That is where I find the command  "SET VARIABLE answer $VALUE" you used in
your example script.

In the list of commands, there is a "EXEC APPLICATION OPTIONS"  command.  I
thought app_rpt was an asterisk application and I could make some calls to
it.  Maybe I can only call the few things that can be called from the
dialplan.

The other way I can coerce asterisk/allstar to do something from a script
is to call asterisk with the -rx options followed by a command string.  I'm
sure you know this because I have seen some of your scripts.   I was just
under the impression that AGI was the "new thing" to replace calling
"asterisk -rx".  I was hopeful that everything I could do with what I
thought was "the old way"  could be done the AGI way.  Guess I was wrong.
