Ah, good idea! I assume even a global variable could be used instead of using db routines...
Where this doesn't work so well is when trying to implement least-cost-routing using local calling areas spread over satellite offices. Here's an example:
Office A has 4 Telco lines.
Office B has 4 Telco lines.
Office A and Office B have 8 station sets each.
Office A and Office B both have Asterisk boxes.
Office A and Office B are long distance calls away from each other, so they use IAX for interoffice calls, and would also like to utilize VoIP to extend their local calling area.
If an employee from Office A wants to make a call to someone in Office B's local calling area, the system will need to follow the following logic:
1) Is there a telco line available in Office B? 2) No? Use a local line in Office A and make a long distance call. 3) Yes? Place the call through a local line in Office B. 4) Worst case, all lines are busy. Let the user know.
Bottom line, the call has to go through without any intervention from the user, but try the cheapest method first.
We're already written an AGI module to handle the call routing (ie. which numbers are locally available from each Office), but I'd like to be able to handle line availability as well.
Why use an AGI? This seems to be easily done with the dialplan, unless I'm missing some additional sophistication that you're not mentioning.
Any idea how this could be done?
TRIP (RFC2871 and RFC3219) Not implemented in Asterisk yet - looking for programmers. See my posts to the -dev list last month.
This is probably overkill for a two office situation, but imagine you have three hundred offices...

And to answer Wade's question: to limit outbound calls on a particular path, you'd use a local db set routine. In other words, every time a call is created to that particular SIP peer, you'd add 1 to the counter, and every time a call was hung up out of that pool, you'd subtract one.
