[SR-Users] Dispatcher call id hash for server side invite

Thanks for the explanation! I finally got the dispatcher working in an
active / passive Kamailio cluster in front of three FreePBX servers. I was
using the Asipto Kamailio and Asterisk real time guide as a starting point
so it had the WITHINDLG route. I ended up modifying the TOASTERISK route to
call ds_select_dst and the FROMASTERSK route uses an htable for matching
IPs off a mySQL view of the Kamailio dispatcher table. I also have some
modifications to the REGFWD route. We'll see how performance is today as I
did have to use a sqlops query to lookup the dispatcher set ID for
TOASTERISK and REGFWD depending on the authentication ID. This setup is
responsible for around 1000 extensions with 2000 devices for a high volume
call center.
