[Freeswitch-users] 2 FS with shared database, cannot call subscribers on different servers

Thu Nov 26 11:58:52 MSK 2015

Hi Michael,

I'd recommend using something like Kamailio or Opensips in front of the
FreeSWITCH boxes.

>From personal experience (with Kamailio) the learning curve is quite steep
(for me it was at least), but it definitely pays off in the end, plus it
greatly improved my understanding of SIP.

STUN is used for devices to discover their public address, so wouldn't help
the situation you currently face.

Just my input.

Regards,
Luke
