asterisk users - Jul 2011 - Controlling max simultaneous calls for a group/.call files

We are building an app that will initiate outbound calls using .call files, and
each call can be a different duration (eg: 1min to 5min).  These calls will go
through an Asterisk service with other calls/apps running.

I need to control the MAX number of channels in use so I don't overload this
server.   What is the best way to ensure I stay within an arbitrary limit (eg:
10 simultaneous call files in process at once)?

The call files will be written to the spool directory by a bash file, so ideally
the bash file should have visibility into the number of .call files in process.

Thanks!

Use the Asterisk manager instead.

Or do something like:

asterisk -rx'core show channels'|grep "active channels"|cut
-d' ' -f1

and either store the output in a variable or pipe it to a file.

The other alternative would be to do "core show channels concise"|grep
accountcode (where accountcode is what you originated the call with) and 
then do a "wc -l" on the output to count the lines.

That's the cue for someone to explain some cleaner way to do it with a 
single bash command :-)
