OK, so I added in 3CX the number of the trunk as the caller ID number. and I also added the SDA to my extension. OVH already had the trunk number as caller ID.
Now, I get the "Not available" error message. And this in the logs:
Device PHONENUMBER dialed on (AnyLine@Paris) had no available outgoing trunk(s) for Call(from "Florian BURNAT";tag=3835397371 to PHONE NUMBER)
Actually, what appears instead of phone number is a standard 10-digit French phone number
