[Freeswitch-users] Distributing SIP registrations using ODBC

[Dan Lane]

Yup, that was how I plan to fix it using LUA to figure out where to
route the call (possibly proxying it via the other FS server).

Just wanted to check I wasn't re-inventing the wheel before I go ahead
and do it as it seems like the sort of issue other people would have
dealt with.
