See the end of quoted log. It tries to resolve
```<sip:s7t25aae@r2r3d4o15av3.invalid;transport=ws>``` as traditional SIP URI, and
fails. Need support of WS and WSS URIs.

I'm trying to fix this in code by myself, but any guidance and help is appreciated, as
I'm not experienced in Kamailio internals.

What version are you using? Have you used set_contact_alias() for the initial invite +
200ok?

No, I don't have ```set_contact_alias()``` anywhere in routing config. Going to google
how I'm supposed to use it.

I have two ```add_contact_alias()``` entries, my config is based on

Cnxcc is actually sending the BYE correctly but the destination is unreachable, and
that's a routing problem.
As Daniel mentioned, make sure you are using contact alias.

Actually it is NOT sending BYE because it fails to resolve the destination.

Could anybody recommend a good place and a good codeline to insert to this config for
that? https://github.com/caruizdiaz/kamailio-ws/blob/master/kamailio-ws.cfg

Procedurally speaking, it is. The module delivers the instruction to the networking layer
which is the one responsible for sending it and reporting failures. Cnxcc assumes every
piece of data is correct and acts on that basis.
The config you are using is outdated, check the logs and try to change it according to
your network topology. I will try to update it during the weekend.

Carlos is right about cnxcc doing the right thing, the bye is anyhow sent effectively by
the tm module, but it doesn't have the proper destination details, because when dialog
was created the contact address was left only the one set by the browser. In webrtc, the
contact address is an 'invalid' value.
Replace add_contact_alias() with set_contact_alias().

@caruizdiaz sorry for that stupid comment :) Would be very interesting to check your
updated config, and thank you for the config you have already shared.
Thanks a lot @miconda! Now it works.
