Hello,

does it add two record route headers when calling to an UDP destination? IIRC, the condition for double route is that incoming socket is different than outgoing socket and I am not sure if Peter updated it to detect a different sub-protocol type (as ws/wss are on top of tcp/tls).

Cheers,
Daniel

Have you tried the latest code on the 4.0 branch as I am sure there are fixes that have been made since the last release?

Also, if using WebSockets I do strongly recommend you try Git master if you have any problems. There may well be fixes there that haven't been back-ported to the 4.0 branch yet.

Hello,
Thanks for a quick reply.

No, outbound module is not loaded. As I understood from RR docs double_rr won't work if outbound module is present.
I've added mhomed=1 to my config, but record_route() still inserts only one rr with transport=ws.
Are you using outbound? If you are I suggest trying git master rather than the 4.0 branch.

Regards,

Peter

Hello.

I'm trying to configure kamailio as a gateway between Websocket and TCP/TLS transports.

When I call record_route() for an initial INVITE that comes via WS and will be forwarded via TCP to a registered UA kamailio inserts only a one record-route header with its IP and transport=ws instead of two record-route headers with both incoming/outgoing transports.

This behaviour breaks in-dialog requests routing.

rr module parameters are:
modparam("rr", "enable_full_lr", 1)
modparam("rr", "append_fromtag", 0)
modparam("rr", "enable_double_rr", 1)

I use:
- kamailio-4.0.2
- sipml5 as sip client

Can anybody point me in the right direction to understand why it happens ?
