Dual Home CMS - Skype - maximum sessions?

[gfolens]

I've deployed CMS v2.2.9 and dual home meetings with the Skype environment.

On CMS you need to define 1 or more Skype users ("username" and "number of registrations").

I've added 9 Skype users (service accounts) and they all register.

How many concurrent dual home conferences can I now create with 9 Skype users?

I tried to find it but got no clear answer.

Here some numbers I found on MSFT:

1 Skype for Business account is capable of up to 12 TURN allocations; so with 1 registration, 12 calls are possible.
So, if you have 9 accounts registered to Skype for Business, you're capable of up to 108 calls between CMS and Skype for Business.
