Hello

I have my servers behind a NAT, with servers that make a call with bypass media / direct media all works fine. But when my media servers need to process audio I'm having issues. Looking at the SDP my local IP of the server is in there.

I changed my config to add the nethelper.so and add the below:

# ----- NAT Helper -----

#!ifdef WITH_NAT

#modparam("nathelper", "rtpproxy_sock", "udp:127.0.0.1:7722")

modparam("nathelper", "natping_interval", 30)

modparam("nathelper", "ping_nated_only", 1)

#modparam("nathelper", "sipping_bflag", 7)

#modparam("nathelper", "sipping_from", "sip:pinger@kamailio.org")

#modparam("registrar|nathelper", "received_avp", "$avp(i:80)")

#modparam("usrloc", "nat_bflag", 6)

#!endif

In my route I added:

if (search("User-Agent: FS Box") {fix_nated_sdp("3");};
