I am working for a big corporation from a remote location. The default for voice chat is Skype, which works most of the time alright. Unfortunately because of the VPNs, Firewalls and other networking layers we have to fight through, the voice chat functionality is not working most of the time. So we are looking for an alternative.
We have some requirements:
- It has to be E2E encrypted because the stuff we discuss is classified
- Preferably it uses only default ports like 80/443
I've tried Telegram which was working for text messages bus wasn't connecting when we tried an voice chat.
