For a call invite from a phone to an load balanced asterisk server farm I
can use ds_select_dst with hash over callid for the algorithm. What I don't
understand is what happens for a server side invite. Say user A calls user
B. The server will send and invite to user B's device. User B's device will
reply and ds_select_dst won't have the call id hash so it will choose a
random server, which might not be the server sending the invite. How do I
mark these server side invites so the call hash is known by kamailio? Or am
I thinking about this the wrong way?
Thanks,
Ryan
