Hi Pranzo !
Thank you for your help. :-)
Here are some screenshots from how I set Wengo through Voxalot :

Wengo is registered but when someone calls me on my french number, my phone doesn't ring and the caller hears this message : "numéro non attribué".
If Wengo is registered directly on my SPA1001, no problem : the phone rings and and I can be reached.
What's the problem ?
Thanks
