Hi
I've run the test again with log level set to 4, and I don't see anything
related to route header parsing, I don't see any trace of the received uri
value
I've also tried with outbound module loaded, no change
I've also tried with WITH_NAT defined or not, no change
Cheers

Hello,
try to run with debug=3 in kamailio.cfg and watch the logs, you may get
some hints about what happens, maybe there is some error in processing or
overwriting of destination address.
Cheers,
Daniel

Hi
I'd like to make sure I've understood correctly how use_received in path
module is supposed to work, because I don't get what I expected to get
after reading the documentation
I've got a little set up with a UAC behind a NAT registering to a kamailio
registrar through a kamailio edge proxy (he UAC is a simple sipp script
simulating a UAC behind a NAT)
path is enabled on both EP and registrar, and use_received is set to 1 on
EP
the path, contact and via headers in the REGISTER going from the EP to the
registrar are :
Via: SIP/2.0/UDP
192.168.26.129;branch=z9hG4bK20da.9f4ab6ad25eae6acdd4bd4d655b320ce.0
Via: SIP/2.0/UDP 10.0.0.5:6060
;received=192.168.26.1;rport=23456;branch=z9hG4bK-105-1-1
Contact: <sip:1000@10.0.0.5:6060>;methods="INVITE, ACK, BYE, CANCEL,
OPTIONS"
Path: <sip:inside@192.168.26.129;lr;received=sip:192.168.26.1:23456>
where 192.168.26.129 is obviously the edge proxy
then I place a call to the UAC through registrar
the EP receiveds the following INVITE :
INVITE sip:1000@10.0.0.5:6060 SIP/2.0
Record-Route: <sip:192.168.26.142;lr>
Via: SIP/2.0/UDP
192.168.26.142;branch=z9hG4bKdf25.142eebc72e940d07ad983a858c67f64e.0
Route: <sip:inside@192.168.26.129;lr;received=sip:192.168.26.1:23456>
Via: SIP/2.0/UDP 192.168.26.1:34567
;received=192.168.26.1;rport=34567;branch=z9hG4bK-107-1-1
From: "1001" <sip:1001@my-fake-domain.com>;tag=107-1
To: <sip:1000@my-fake-domain.com;user=phone>
CSeq: 1 INVITE
Call-ID: 1-107(a)192.168.26.1
Contact: <sip:1001@192.168.26.1:34567>
...
The Route header is exactly what is expected, but the edge proxy still
sends the request to the request-URI address (10.0.0.5:6060) instead of
sending the request to the received address set in the first Route header
The path module documentation states :
3.1. use_received (int)
If set to 1, the “received” parameter of the first Route URI is evaluated
and used as destination-URI if present.
kamailio configuration on the EP is almost the default one (just added
path support, and modified the REGISTRAR route to forward the request
instead on saving the contact, so there is not even a mid registrar on the
EP
tried with kamailio 5.3.7 and 5.4.4
thanks
