asterisk users - May 2010 - Best way to limit outgoing calls per trunk

Hi Guys,

I am looking to use System() function along with some bash scripting to
determine if a Trunk is being used during certain time of the day or not.
Here is what I have in mind. Please guide me if you know a better way:

exten => s,1,answer
exten => s,n,System(/tmp/check.sh)

check.sh:
check EPOCH time => do an IF for certain times => Allow mutiple calls in
certain times and only single call at certain times
return back to Asterisk context and report if Trunk would allow more
channels or not...

Something along those lines. Should this be a solid thing to do? I am
looking to use GotoIF and `asterisk -rx "sip show channels"` to grab
results
or `asterisk -rx "core show channels"`

Thanks

Should be solid. After all munin also works on the same lines and it works
solid.

I don't know what version you are running, but check out GotoIfTime.
I use it frequently for office hours.  GROUP, and GROUP_COUNT can help
with limiting on a trunk too
> exten => s,1,answer
> exten => s,n,System(/tmp/check.sh)
exten => _X.,n,GotoIfTime(7:30-16:30,mon-fri,*,*?multicall)  ; Within
this time, go to the label 'multicall'
<code to limit to one call>
exten => _X.,n(multicall),Verbose(3,We can call more than once)
<code to call multiple times)

Thanks for the input.

Is there no Asterisk command in dialplan to return true or false or number
of channels per trunk rather than going to bash script?

And if I do the bash script how can I use "sed" and "awk" to
search for the
right words to see if trunk is in use or not.

A bit detail would be really helpful.

Thanks,
Bruce

Using the GROUP/GROUP_COUNT functions in the dialplan is a better way.

Using system() will mean creating a bunch of processes (each 
sed/awk/cut/etc command).

Thanks for the tip. I have been checking those two options. Would you be
able to provide an example of how GROUP or GROUP_COUNT may check for a trunk
usuage? From what I see is that you have to assing certain routes a group
and then count the group, but how I do include a trunk in the group?

Thanks

Here is how I do it.  It is based on Asterisk 1.6.1.x, and I created a
generic sub-routine to call for limiting trunks to a specific number
of calls.  The code is documented, so it should give you a good idea
of how to use it.
