asterisk users - Sep 2008 - Split incoming call volume across queues on several asterisk servers

Hi,

   I was wondering if there is anyway to split, say, 300 calls that come in
from the SIP provider across 10 asterisk servers with 30 agents each,
without having the telco do the splitting. Is there any way to do call
distribution, e.g. we send an incoming call to a similar queue on the next
asterisk server if all agents on the first asterisk server are busy and the
queue already has a certain number of calls in it?

Thanks,

You can set up a proxy to round-robin/load-balance the incoming calls 
across three servers.

If you need to do this with a view to queue utilisation, an outside 
process can be set up to mediate this via the Manager API and provide 
this information to the proxy process in real time.

A proxy can also be set up to roll calls over to another Asterisk server 
if that server returns an error status code because all the agents are 
unavailable, such as 486 Busy or temporarily unavailable.

You can, also, of course, do this in the Asterisk dial plan itself - 
fiddle with the timeout values on the Queue() app.  However, in this 
paradigm, the first Asterisk box is going to have to cross-connect the 
call to others in the series, in a daisy chain.  But if you can avoid 
media handling in such scenarios (i.e. use re-INVITEs), that shouldn't 
be too bad.
