Hi there,
I've been setting up SER for a testing server on the local network behind a
NAT. I'm having problems understanding how to setup the NAT routing in the
configuration file.
My understanding is that IPTel has already setup advanced NAT routing on the
free service (as per the website).
Is it possible to get a copy of the configuration file (atleast the part
that has the NAT routing stuff). This would help me immensely in getting
proper nat traversal setup as it already works great on the IPTel server.
Not sure who I would contact in regards to this, but this seemed like a good
place to start.
Kind regards,
Andy Savage

Guys,
I'm successfully using a Kamailio + RTPproxy setup in bridge mode with most
of my Gateways. My setup includes two different interfaces one with a public
IP and teh other with the private IP.
Now I'm facing some slight issue. Some providers won't accept my calls (or
calls will have some strange behavior) if the Contact header has an IP out
of immediate range.
I tried to use fix_nated_contact() function but as per my topology, this
function will not change the contact header because the IP is already the
one on the interface.
Example:
U 192.168.200.X:5060 -> 192.168.200.Y:5060
INVITE sip:111160911097@192.168.200.Y SIP/2.0.
Via: SIP/2.0/UDP 192.168.200.X:5060;branch=z9hG4bK096baacc;rport.
From: "Uriel Rozenbaum" <sip:60911100@192.168.200.X>;tag=as32794d5e.
To: <sip:111160911097@192.168.200.Y>.
Contact: <sip:60911100@*192.168.200.X*>.
U 200.A.A.A:5060 -> 200.B.B.B:5060
INVITE sip:898960911097@200.B.B.B SIP/2.0.
Record-Route: <sip:200.A.A.A;r2=on;lr=on;ftag=as32794d5e>.
Record-Route: <sip:192.168.200.Y;r2=on;lr=on;ftag=as32794d5e>.
Via: SIP/2.0/UDP 200.A.A.A;branch=z9hG4bK5222.14fbf4f7.0.
Via: SIP/2.0/UDP
192.168.200.X:5060;received=192.168.200.X;branch=z9hG4bK096baacc;rport=5060.
From: "Uriel Rozenbaum" <sip:60911100@192.168.200.X>;tag=as32794d5e.
To: <sip:111160911097@192.168.200.Y>.
Contact: <sip:60911100@*192.168.200.X*>.
Is there any way to let know Kamailio the outgoing IP I'll be using and fix
the contact accordingly?
I can trigger this change after I know the destination IP.
Thanks!
Uriel
Thx for reply.
This is what i get with patch applied (is not pretty readable, but what i
can see is "^M" char that could be the cause of the problem...or in rpid
field the status "unknown")

Hello,
What does the following stat mean when you run the " openserctl moni "
sl: received_ACKs = xxxx
I did some digging and I got the following explanation... But am not sure if this is an
error in operser or an error on a message received by openser or what?
" sl: received_ACKs - number of received ACKs due sending negative replies. "
any help is appreciated.
thanks,

Hi,
We need to add header on the failure route.
Exemple:
On failure 404 Not found, we need add header
Reason: Q.850; cause=1
We tried this in failure_route:
if(t_check_status("404")){
xlog("L_ERR", "404 Not found\n");
append_to_reply("Reason: Q.850; cause=1\r\n");
xlog("L_ERR", "404 Not found apres\n");
exit;
}
and
if(t_check_status("404")){
xlog("L_ERR", "404 Not found\n");
append_hf("Reason: Q.850; cause=1\r\n");
xlog("L_ERR", "404 Not found apres\n");
exit;
}
The twice doesn't work.
Someone can help me?
Thanks,

Ok, this is probably an easy question:
Say I have my kamailio server set up and all of my voip clients are
gleefully calling each other... but now I want to connect them to the PSTN.
Can I set up kamailo to trunk calls using a few grandstream gateways? or is
Asterisk neccesary?
Sorry if the answers out there, but I haven't found anything that answered
the question directly.
I'm a linux admin, but I'm new to PBX's and the like. I've installed
kamailio in the past using instructions specific to that situation, but
haven't configured trunking (or I didn't recognize thats what it was)
references to howtos or tutorials would also be greatly appreciated
Thanks for your help,
Jared Martin
