[SR-Users] Kamailio NAT AWS EC2

[Arsen]

Since you are on Amazon AWS, make sure that you advertise the instance
public IP address in the listen parameter

listen=udp:private_ip:5060 advertise public_ip:5060

according to the default kamailio cfg rtpproxy will be applied if an INVITE
request passes nat_uac_test("19")
https://kamailio.org/docs/modules/5.1.x/modules/nathelper.html#nathelper.f.nat_uac_test

make sure that rtpproxy is installed and running, you also need to set
public IP address in the rtpproxy startup options.
