[SR-Users] Kamailio NAT AWS EC2

[Ilie Soltanici]

Hi,

First of all, check if SIP Traffic is going through your SIP Server, not
directly between Endpoints. To do this check if Record-route parameter is
set in configuration file:

record_route();

Also, be sure that in SDP body you have External IP of your
Kamailio/RTPproxy. If Kamailio is behind NAT you may need to use
fix_nated_sdp function from nathelper module:
