If ALL clients are outside your network and SER is behind NAT, you can
advertise your public IP in ser.cfg.

advertised_address="your public IP"


Replace record_route() with record_route_preset("your public IP").

For rtpproxy, I think it must be internet facing (correct me if I'm wrong)
beofore it can relay RTP packets outside your network. That means rtpproxy
cannot be behind NAT.
