[Linphone-users] Linphone 5.x ignores IP address and port of a contact

[Andrey Semashev]

Hi,

I'm having a problem with Linphone 5.x (specifically 5.0.12, but it also
reproduced with prior 5.x releases) on Linux desktop. I have a contact
"sip:conference@192.168.1.2:7060" (note the IP address and port are
explicitly specified in the contact URI). When I'm initiating a video
call to the contact, the SIP INVITE message is sent to address
127.0.0.1:5060, and consequently the call is never answered as noone is
listening at that address and port.

I've collected logs from Linphone 5.0.12:

https://www.linphone.org:444//tmp/6407c2c3b4c30_4fcfb112955fbb02b332.gz

This is on Kubuntu 22.04. Note that it says "message sent to
[UDP://127.0.0.1:5060]" for the first INVITE.

The same worked with Linphone 4.x (specifically, it works with 4.4.11)
on the same system with the same contact - making a video call succeeds,
I'm getting video and audio. In logs from 4.4.11 I'm seeing "message
sent to [UDP://192.168.1.2:7060]" for the initial INVITE, as expected.
