So the users from a country will be preferred to his nearby server by DNS routing.

Similarly users from different countries will be registering to their nearby kamailio sip servers.

All the servers share a common user location table on database.

Now the users are getting registered fine, with no issue.

We want the users at one location should be able to call user@other-location using the user location contact information.

When we tried, the INVITE is sent on common domain name and that reverse resolves dns to same server and gets a 404 not found.

I need some suggestion / ideas in order to make it happen.

Thanks
