I have an AWS ec2 instance with Kamailio and rtpengine configured. I
am having a challenge of no voice on calls. I have sip client on my
mobile phone and soft phone on my laptop and the two are on different
networks behind nat. Signaling is working fine but there is no media
and when I check on on the SDP the call logs are showing private ips
instead of public ips : o=- 3 2 IN IP4 192.168.1.33 and c=IN IP4
172.31.36.50. I understand this is a NAT issue but I am failing to see
where is the challenge. My rtpengine seems to be working fine .
Most likely you need to use the "advertised address" notation in your
interface config as on AWS generally you don't have the public IP
address bound on a local interface. So something like
interface = external/172.31.36.50!13.246.88.123;internal/172.31.36.50
