Hello,
You can use the dispatcher module to accomplish this. Please check the
hash_pvar param [1] and the ds_select_dst() func [2] with the 7th
algorithm.
So what you need to do is put the $si ( source IP ) in the hash_pvar
AVP, and then call ds_select_dst("1","7"). This will lead to having
calls from the same IP to be routed to the same Asterisk server.

I am planning to use opensips to load balance/direct traffic to
asterisk servers. We have about 40 locations (will have many more)
with 5 phones each, and we would like to have all the traffic coming
from a location to go to the same asterisk server; i.e., if the first
SIP message from location 1 is sent to Server A, we would like the
other messages coming from there also sent to A. Is this possible?
Traffic from each location will be more or less the same, so can
opensips do the load balancing maybe in a round robin style (I guess
via dispatcher) taking the source IP into consideration; e.g. location
1 goes to server A, location 2 goes to server B, location 3 goes to
server C, location 4 goes to server A, etc.?
The reason I want to do this is to keep the device state information
for each location on the same Asterisk server (I'm not sure if
asterisk can store device state data in a database for realtime
updates and lookups) and maybe avoid extra messaging (e.g. openais)
betwen asterisk servers to distribute the device state data.
I'm very new to opensips and asterisk...
Thanks,
Matt
