[Freeswitch-users] Distributing SIP registrations using ODBC

[Dan Lane]

Hi Guys,

I have a cluster of FS boxes all sharing SIP registrations using ODBC
and under certain circumstances I can register Client-A on FS-A and
Client-B on FS-B and make calls between Client-A and Client-B without
issue as the relevant FS box knows how to get a call to the client
from the shared registrations table.

However when the callee client is behind NAT (or using a SIP client
configured to only allow calls from a server it has registered with)
the call gets dropped by the NAT router (or client)

I can fix this easily with some LUA but before I do I wanted to check
if there was an advisable or recognised FreeSWITCH way to work around
this.

Has anyone else solved this issue already?

Regards,
Dan
