Carsten, will I need to remove previously installed version of RTP proxy before installing this version?

Hi,

you can also check the RTPProxy replacement from Sipwise:

- https://github.com/sipwise/mediaproxy-ng

It supports working behind NAT with advertised IPs. I've used it on
Amazon EC2 myself.

Kind regards,
Carsten
