Now using Signal protocol
With more than 2 on the line, Skype has problems. But it's MS, so work think it must be used.
The new Skype, like WhatsApp, Allo and Facebook Messenger will use Signal's protocol, with Microsoft's added ... er ... magic.
So why not use Signal*? No slurping, open source, non-profit. As recommended by security nerds. Works a treat.
* I know, I know. Power, control, brand, the ability to read everything out of your phone and report to the Mothership etc
