So let me get this straight:

Paris is missing on the list?
Are they serious to even call this a “service”?

Sorry, but as long Paris is missing on the list, you can’t say there is a PSTN availability for France at all…

    Often it’s really hard to get numbers for capital/major city area codes, It’s also a challenge for London and New York, often the area codes are maxed out. Not making excuses, I would rather it’s there, but it’s not a Microsoft specific issue, but often a general carrier challenge.

our company is located in Neuilly (Nearby Paris). This city is not (yet) on the list, so i have chosen two phone numbers from nearby cites (Nanterre & Boulogne-Billancourt) but none of them seem to be working.

Can you advice ? Thanks.

Hello Tom
do you know if MS is communicating about their capability to port existing numbers on this new PSTN Platform for France?
