[asterisk-users] Using SetVar with System() is it possible?

[bruce bruce]

I am using Asterisk v1.4.x

I have got php along with phpagi to report back using a system call within
php to asterisk -rx but it's buggy. For one thing php is hanging sometimes
and not returning anything.

Wondering if I can run search to see if a g.729 channel is up or not using
only the dial-plan. I want to get a TRUE or FALSE in a var for it.

I was pointed to GROUP_COUNT but that doesn't cut it for me in this case.

There is gotta be some simple dial-plan to find out if a trunk is being used
or if a g.729 call is going through or if a specific destination is being
dialed with first three digits being 789 (for example) as all of those
variables can help me move to next step which is to decide to place a second
call through the same trunk or not.

Any inputs?

Thanks a lot
