UA1(192.168.0.1) --> kamailio (internal:192.168.0.2 public:1.1.1.1) -->
UA2(2.2.2.2)
if in UA1 INVITE, I write KSR.rr.record_route().
so UA2(2.2.2.2) received sip msg (Record-Route: <sip:1.1.1.1:7080>), so Kamailio
can received BYE/ACK from UA2.
but，Kamailio can't received BYE/ACK from UA1.
if in UA1 INVITE, i write KSR.rr.record_route_advertised_address("192.168.0.2"),
then Kamailio can received BYE/ACK from UA1, but not from UA2.
what can i do, let Kamailio receive BYE/ACK from both sides ？

There are many possibilities.
One of - use listen names and advertised address with allow_double_rr
option.
Once you do that - you'll be able to add 2 rr headers, and kamailio will be
able to handle gateway functionality between interfaces via RR/Route headers

try using a different source port for the outgoing side. i.e. use 2 ports

Hi
You also uploaded a pcap trace, using this link (which you sent directly to
me).
- https://1drv.ms/u/s!AkdU9Y6p5WVyjnrodIHt6EgS-h3U
I read it and it's clear what's going wrong.
This is your desired flow.
192.168.0.11 ---> 192.168.0.2 ---> 122.97.130.198
192.168.0.11 <--- 36.140.122.12 <--- 122.97.130.198
In this, your INVITE goes to the public IP address (122.97.130.198) like
this.
INVITE sip:+8618626439917@122.97.130.198:15060;user=phone SIP/2.0
Record-Route: <sip:36.140.122.12:7080
;lr;ftag=5c1a6b917a705e9e;did=2c4.8532;nat=yes;vst=AAAAAAAAAAAAAAAAAAAAAAAAAAALAAAIARYfAx4cCw4IAgE1MDYwO3VzZXI9cGhvbmU->
Via: SIP/2.0/UDP 36.140.122.12:7080
;branch=z9hG4bKe61a.5fe9d645ef1bbe470ca6d57fa20375bf.0
Via: SIP/2.0/UDP 192.168.0.11:45642
;received=192.168.0.11;branch=z9hG4bK98457cb5b0e44505;rport=45642
The 200-OK goes to the UAC (192.168.0.11) like this.
SIP/2.0 200 OK
Via: SIP/2.0/UDP 36.140.122.12:7080
;rport=7080;branch=z9hG4bKe61a.5fe9d645ef1bbe470ca6d57fa20375bf.0
Via: SIP/2.0/UDP 192.168.0.11:45642
;received=192.168.0.11;branch=z9hG4bK98457cb5b0e44505;rport=45642
Record-Route: <sip:192.168.0.159;r2=on;lr=on;nat=yes>
Record-Route: <sip:122.97.130.198:15060;r2=on;lr=on;nat=yes>
Record-Route: <sip:36.140.122.12:7080
;lr;ftag=5c1a6b917a705e9e;did=2c4.8532;nat=yes;vst=AAAAAAAAAAAAAAAAAAAAAAAAAAALAAAIARYfAx4cCw4IAgE1MDYwO3VzZXI9cGhvbmU->
The problem is, as you know, that the ACK from the UAC is routed to the
public IP address 36.140.122.12, whereas you want it to be sent to the
private IP address.
For this, double record-routing is required, as suggested earlier in this
thread.
My best guess is that your proxy has one IP address. A problem is that we
now know that you have your listen directive set to listen on the private
interface, but always advertise the public IP address, but this is not what
you want. You want to advertise one address in one direction and another in
the other direction. You want two Record-Route header fields when relaying
the initial INVITE.
I see two possible solutions (but there may be others).
- Get your proxy server to listen on two addresses, and force the socket
when relaying messages. This can be cumbersome and tricky.
- Try using the record_route_preset() function from the rr module. This can
be used to write the two Record-Route header fields exactly as you want (in
the correct order, of course).
I recommend the second option, because it would be simpler for me to
implement. I don't know how to do it in KEMI, though.
