(First of all, I’m not sure it’s convenient to post your log file on a public mailing list…)

From your logs which I quickly looked at, it could be that there is a mismatch between AVPF settings between the client and the server. You may want to try disabling it. See the SIP 200 OK answer before this line:

2020-06-24 14:23:05:476 ERROR Incompatible SDP answer received, need to abort the call

To Peio :
Installation of 4.2 version is ok this time after uninstalling properly the older version.
My headphone is yet recognised.
I erased my account and created a new one using « settings/SIP accounts/Add an account ». But nowhere I was asked to enter a password and I can’t send a call anymore, neither receive one.

Here are the logs:

As of my account settings, here is what I have in this order (sorry, it’s in French) :
  • Adresse SIP :
  • Adresse du serveur SIP : <;transport=tls>
  • Durée d’enregistrement : 600
  • Transport : TLS
  • Route : (empty)
  • Paramètres de contact : message-expires=604800
  • Intervalle standard RTCP AVPF (sec) : 1
  • « S’enregistrer » « Publier la présence » et « Activer AVPF » turned to on
  • « Activer ICE » turned to on
  • Serveur STUN/TURN :

If the logs are right, you are still using the 4.1.1 version.

Please ensure that you use the 4.2.0-alpha-90 in the "about" of the
right menu and retry with the right version. I will then need the new
logs if the issue still persists.

You are using an OVH account instead of a account.

Did you configure it with the assistant menu?

Have you modified any of the default settings?

Please ensure that the app is working with linphone accounts before
trying external providers.

Please show me the configuration pf your accounts in settings > accounts
pen icon.
I see in the logs that you are using UDP. As stated in the best
practices page
in our wiki, we strongly recommend to use SIP TLS to avoid many issues
with routers.

Thanks for your answer Peio. I installed the new version: while
installing it, I had many error messages which approximately said «
Error while trying to open the file in writing mode ». I ignored for
all and successfully installed the app with all my contacts, etc.

But I still have both problems... Here is the log of my tries (send a
call and receive one):
What kind of information about my configuration would you need?

Don't worry, your english is clear.

The version you are talking about is 3 years olds and lack a lot of

Please try with the 4.2-alpha-90 available here.

Download it, and enable logs in advanced tab of settings.

If you have some issues with this new version, please send details
about your configuration and logs.

New desktop release will come soon (this week or next week).

I hope my English will be clear enough to explain my problems. I’m a
new user of Linphone on Windows 10 and I use « Desktop 4.1.1 -
Qt5.9.0 » « Core 3.12.0 » version of Linphone. I subscribed an OVH
account to send and receive some calls and I have two problems :

  * Linphone doesn’t recognise my headphones and although it’s
    connected, the sound continues to come out from the computer’s
    speakers. The headphone doesn’t appear in the audio parameters list.
  * when I send a call (to my cellphone for example), instantly
    after picking up the phone, it automatically hangs up.

I can send some details about configuration if needed.

Thanks in advance for your help.
