[Freeswitch-users] FreeSWITCH with external registrar

[Sam Govind]

I'm not very very good at FreeSwitch ATM. I hope for option 1 some other
expert reply.

As far as second option is concerned, this seems good but I think it'll
complicate the code on first layer SBC/proxy.

What I'm thinking is using a single DB for REGISTRAR and Front layer proxy,
whenever an INVITE comes in just check the DB and if usrloc module returns
info corresponding to the callee then use the headers and forward call to FS
to bridge.
REGISTER requests still go to REGISTRAR, I don't think sharing the same DB
would overload front Proxy.
