Hi.
Problem:
SER doesn't talk to rtpproxy or mediaproxy. Nothing even in the syslog
file.
I'm running SER 0.8.14 on debian 2.4.27-1-686 machine. For whatever NAT
support I choose, it seems that I can't get right. I have followed
Paul's post and the default config file without success.
My NAT is a Linux box.
Scernario I: rtpproxy
**ser.cfg snippet - (debug=9)***
if (nat_uac_test("3")) {
log(1, "src address different than via header->NAT detected\n");
log(1, "force_rport and fix_nated_contact and setflag(6)\n");
if (method=="REGISTER" || ! search("^Record-Route:")) {
log(1, " ....it is Register....\n");
fix_nated_contact();# Rewrite contact with source IP of signalling
log(1, ".....fix_nated_contact....\n");
if (method=="INVITE") {
fix_nated_sdp("1");# Add direction=active to SDP
};
force_rport();# Add rport parameter to topmost Via
setflag(6);# Mark as NATed
};
append_hf("P-hint: fixed NAT contact for request\r\n");
};

***END****
In both cases, tested separately:-
->UA get registered with the local IP,
->Check points set indicate "fix_nated_contact()" passed
Where is the problem!!??
