asterisk users - Mar 2003 - Reserving a minimum qty of channels

We have two vrs applications running on the same PRI, on different
phonenumbers. All our traffic is incoming only. 

To make sure one application will not eat all the channels, I'd like to
reserve a minimum of channels available per application. I don't want to
give each app a fixed number of channels, bcz it could be a waste of
resources.

I've tried to find some more info about this in the current docs, but
without success.

Anyone ever tried this? Could you give me a direction where to look? 

Thanks, Ivar.

You could use a global variable like this:

[globals]
max_channels_1=10
max_channels_2=13
appl_1=0

[incoming1]
exten => _.,1,GotoIf,$[${appl_1} > ${max_channels_1}]?hangup|1:2
exten => _.,2,SetGlobalVar,appl_1=$[${appl_1} + 1]
exten => _.,3,do_what_you_want_to_do

exten => h,1,SetGlobalVar,appl_1=$[${appl_1} - 1]
exten => hangup,1,Congestion
exten => hangup,2,Hangup

and similar for [incoming_2]

regards
Martin
