Hi Juliusz,

thanks for your quick answer.

I'm choosing it randomly, but the only time I'm sending an ID is when I'm sending my initial offer to Galène, and later on when Louise connects, it re-use the same ID.
My code is available there:
https://repos.goffi.org/libervia-backend/file/tip/libervia/backend/plugins/plugin_comp_conferences/__init__.py#l130
The `session["id"]` used there is generated randomly with `str(uuid.uuid4())`
(https://repos.goffi.org/libervia-backend/file/tip/libervia/backend/plugins/plugin_xep_0166/__init__.py#l572)

How can I specify the ID to use for downstream, i.e. the offers that Galène pushes to me?

Thanks,
Goffi
