[asterisk-users] Load balance outgoing calls

[Alejandro Recarey]

Thank you Steve, that's a good idea.

If I use a global variable like

--> IF GLB > 2 GLB = 0
dial(iax2/isp${GLB}/${EXTEN})
--> GLB = GLB +1

I believe this could cause a race condition if two calls are sent to
the carrier at the same time?
