Using telephone on meeting

It’s first time I’m using Jitsi meet.
I tried to connect with my handy, selecting french dial-number but I go following issues.

  1. it always speak english
  2. It always asking me for the meet-ID but I don’t have it

How can I fix that ?
Thanks in advance

The page showing you the dial-in also provides the meeting ID.
In the screenshot this is PIN:

Thank you for your answer !
I tried 3 times today and it works finally.
But the language is always english and I will make meeting with people who don’t understand.
But I will try. :slight_smile:
