Hi serusers!
After setting up an almost working ser with nat, rtpproxy and asterisk ivr,
I'm stuck on an hangup problem call if from behind nat. I can't get xlite
BYEs to hit ser (ngrep on ser machine gets nothing on hangup pressed on
client). The address in SEND>> is ser nat internal address and I'm calling
from another nat. This is xlite log on BYE
SEND TIME: 735130
SEND >> 192.168.1.100:5060
BYE sip:asterisk@192.168.1.100:5061 SIP/2.0
Via: SIP/2.0/UDP
192.168.1.5:5060;rport;branch=z9hG4bKE406E7BA9C6E11D98395000272430644
From: gio <sip:gio@SER_PUBLIC_IP>;tag=1837372280
To: <sip:gio@SER_PUBLIC_IP>;tag=as0d4fbf68
Contact: <sip:gio@192.168.1.5:5060>
Route: <sip:192.168.1.100;ftag=1837372280;lr=on>
Call-ID: D6C66B0C-9C6E-11D9-8395-000272430644(a)192.168.1.5
CSeq: 8745 BYE
Max-Forwards: 70
User-Agent: X-Lite release 1103m
Content-Length: 0
where 192.168.1.100 is private ip address of ser and asterisk server and
192.168.1.5 is xlite private address from another private network.
I'm pretty sure the problem is SEND >> 192.168.1.100 shoul be SEND >>
SER_PUBLIC_IP.
Reading past issues I tried fiddling with fix_rport, fix_nated_contact, but no
way. Can anyone please explain the correct way to route BYEs thru NAT?
Other things work: i can hear sounds, talk to other people and record messages
in asterisk boxes.
Please, advice
Thanx everyone
In my ser.cfg commands involved in BYE and nat are the following:
if (nat_uac_test("1")) {
if (method == "REGISTER" || !search("^Record-Route:")) {
fix_nated_contact();
if (method == "INVITE" || method == "BYE" || method ==
"CANCEL") {
# I think I could remove method == BYE and CANCEL with no harm...
fix_nated_sdp("1");
};
force_rport();
setflag(6);
};
};
record_route();
if (loose_route()) {
route(1);
};
if (method=="INVITE") {
if (lookup("location")) {
setflag(1);
route(1);
break;
};
};
route[1] {
if (isflagset(6)){
force_rtp_proxy();
t_on_reply("1");
};
if (method == "BYE" || method == "CANCEL"){
setflag(1);
};
if (!t_relay()){
sl_reply_error();
};
break;
}
ciao
