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

[Elliot Otchet]

Get it via the AMI.  If you're already using PHPAGI, it is trivial to get this data.  You can even find an example of how to call "sip show peers" and output the resulting response.  You avoid using the (-rx) and you get the data you were looking for.

http://phpagi.sourceforge.net/phpagi2/docs/phpAGI/AGI_AsteriskManager.html

<other thoughts>If you're already using PHPAGI often on a busy system, you might want to get more ram, use fastagi to move the PHP load to another system, or take Steve Edward's standard advice and rewrite it in C.  </other thoughts>

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?

The overhead of each 'asterisk -rx' command is noticable. If you have 10
calls or more, this can have an odd effect.

Not to mention that the fact that it is so slow exposes its raciness[1].

[1] Which should naturally be fixed using locks :-)
