[asterisk-users] Dialplan Gurus? Can Asterisk 1.4x CHANNEL function be used to retrieve info about OTHER channels?

[bruce bruce]

Thanks Tiago and Tzafrir. I agree with the heavy load that Tzafrir
mentioned. I already made a phpagi that does a system() for asterisk -rx and
it's not very responsive at time.

So what is the solution guys?

You see, I only want to know if g729 is being used because I want to
determine if a trunk is being used or not. Now, don't be hasty and suggest
GROUP_COUNT to me as I can not use that because I can only see the calls by
"sip show peers" or "core show channels" and "group show channels" doesn't
show me any channels because I do not have control over the calls place as
they are placed by A2Billing.

Any more Gurus want to weigh in more?
