[OpenSIPS-Users] public ip issue with sip provider

[Sammy Govind]

Hi again,
I guess for RTPproxy servers you need to have public IPs, to reduce the
failure risks you can run multiple instances of RTpproxys on different
ports managing separate port-ranges.

Media-Servers/asterisks on the other hand don't need to be on public IPs.

Regards.
