Hello,
Here is a nice tutorial about how to do load-balacing between several
gateways :
http://www.opensips.org/Resources/DocsTutLoadbalancing
You can force sequential requests to take the same path as the original
INVITE message by using the Record-Route mechanism. So basically you
will load-balance just the initial requests ( INVITE ), and let the
sequential requests within the dialog follow the same path.

Hello all,
I was reading the documentation on the dispatcher module and it says:
"Is dispatcher dialog stateful?
No. Dispatcher is stateless, although some distribution algorithms are
designed to select same destination for subsequent requests of the
same dialog (e.g., hashing the call-id)."
I am trying to load balance calls between different asterisk gateways,
and I think the round-robin algorithm would be ideal (I would like the
option of having a weighted round robin, but that is beside the
point). I don't understand the use of the dispatcher module if, for
example, the CANCEL request from the originating caller is sent to a
different asterisk box than the one that had the INVITE request. As
far as I can read into the module, there is no guarantee that the
requests in the same dialog will go to the same box.
How can I setup the dispatcher to load balance between asterisk gateways?
Regards,
Alex
