Blizz: End to End Encryption

I've been trialling Blizz since March 2017. I only became interested because I was looking for VOIP options with true end to end encryption and found this article online:

https://www.teamviewer.com/en/company/press/blizz-by-teamviewer-addresses-web-conferencing-and-onlin...

where, as the second point on the page, it states:

Secure: Blizz by TeamViewer is End-to-End Encrypted and Harnesses Proven TeamViewer Meeting Expertise

Yet if you try to google +Blizz +"end to end" today (use the "verbatim" option to ensure you don't get "related results" you're not interested in) and you'll get zero results.

So first question: Does Blizz offer true end to end encryption for its VOIP service?

second question: If it does, how does it cope when adding either late joiners to an existing session, or "dial in" users (neither of whom can be using the same shared key)?

Dear HarryStottle 

Thank you for your questions.

Meetings ( Voip services) with full clients  (Windows, macOS, Android, iOS) are end to end encrypted.

At the moment, you can refere to TeamViewer security statement to read more about TeamViewer sessions encryption: 

https://trust-static.teamviewer.com/wp-content/uploads/2017/07/TeamViewer-Security-Statement-en.pdf

For participants joining via phone, the connection is encrypted to the point where we handover the audio stream to the provider. A phone call cannot be encrypted and at this point it’s no longer in our hand.

If you want to avoid "dial in" users, you need just to set a password (meeting with password). In this case only full clients are in the meeting and all connections are fully e2e encrypted.

Best regards
