yeah i didn't use the same port 5060 for both tcp and tls, i switched between them for testing.

To be more clear
10.0.2.15;transport=tcp is the inbound RR when i use tcp
10.0.2.15;transport=tls is the inbound RR when i use tls

one in tcp is ok, but one in tls is not as per rfc3263#section-4.2, my tls uri in the RR will make the client route ACK/BYE to 5061
If no port is
specified, it uses the default port for the particular transport
protocol

i just wanted to confirm if it's a minor kamailio bug, or i missed something as I also found your comment
https://lists.kamailio.org/pipermail/sr-users/2015-May/088129.html
The addresses in the headers should be those where kamailio
can receive traffic. If the port is 5060, it can be omitted, being the
default value for sip.

Many thanks for your time, Daniel,

Hello,

not sure I understood properly, but if you want to use port 5060 for both tcp and tls is not working. Better just use it for tls only.

Cheers,
Daniel

Hi Joel, thanks for verification, it was ok to me when using the default 5060 for udp/tcp with port omitted in the RR, the calls should be routed properly.
But it don't work if i use the same port 5060 for tls (i know this is a bit weird, but i want to re-use the port due to customer firewall restriction), the port is still omitted and `ACK/BYE` routed wrongly to MY_ADDR;transport=tls (5061).

I only want to make sure whether it is not able to explicitly add 5060 port to the RR when using tls or i just make it wrong with my configuration.

By SIP definition if the port is the default (5060 for udp/tcp, 5061 for tls) it's not mandatory, that's why if you choose any other port you specifically see it in the RR.

Hi all, i was using kamailio 4.2.1 located in 2 networks
listen = tcp:MY_ADDR:5060 advertise MY_ADDR:5060
listen = tls:MY_ADDR:5061 advertise PUBLIC_NAT_ADDR:5061

when the call made from the inside network to out side, running `record_route()` resulted in 2 Record-Route headers added (enable_double_rr=1)

Record-Route: PUBLIC_NAT_ADDR:5061;transport=tls;lr
Record-Route: MY_ADDR;transport=tcp;lr

That was totally fine omitting the port in the first Record-Route when using tcp (or udp) on the first realm, but when i start switching to tls, it caused trouble

Record-Route: PUBLIC_NAT_ADDR:5061;transport=tls;lr
Record-Route: MY_ADDR;transport=tls;lr

The client is then told to send ACK/BYE to `MY_ADDR;transport=tls` located at `MY_ADDR:5061` as per rfc3263, then the call would failed.

I had another try with `record_route_preset("PUBLIC_NAT_ADDR:5061;transport=tls", "MY_ADDR:5060;transport=tls");`, it really did add what i want with explicit 5060 port on RR, `ACK/BYE` travel on the correct path, but `loose_route()` only consumes the local `Route` header (it should consume 2). So my assumption is to stick with `record_route()` function to make `loose_route()` work properly.

I tried using another port on the local realm, e.g: 5062 and the port is explicitly added to the Record-Route header `MY_ADDR:5062;transport=tls;lr`
So is `5060` couldn't be explicitly added to the inbound Record-Route, or i just missed something?

Any help will be appreciated.

P/S: I also tried 4.4.7 and it still omit my 5060 port in the RR.
