[Asterisk-Users] Is there a way to find free zap channels on remote servers ??

[Paco Perez]

Hello:

I would like to know if there's a way to request free chanels from remote 
asterisk servers ?

My idea is to make an agi returning a dial to inter-asterisk connected servers 
when there's not enought chanels on local server, maybe like a ping to all of 
them or maybe requesting to a central server where all the *s send and 
request information about available chanels each 2 or 3 seconds, it has not 
about dial plans because I make LCR first and I have a flat rate for national 
calls, It is about using less analog lines with constant costs every month.

Maybe Asterisk has internals for manage this situation (like virtual group of 
different asterisks chanels) But I would like to be sure 90% that a free 
chanel is going to be available when I dial to another asterisk and not to 
have calls rounding over Internet.

Thanks for your comments.
