Amazon recently announced launch of Amazon Chime , Chime is a new unified communications service that makes meetings easier and more efficient than ever before. Using Amazon Chime one can do online meetings, video conferencing, make calls , do encrypted text chats and share content.
Amazon Chime features security capabilities built directly into the service. Messages, voice, video, and content are encrypted using AES 256-bit encryption. The visual roster makes it easy to see who has joined the meeting, and meetings can be locked so that only authenticated users can join.
Chime is available for Windows, Mac OS X , Android and iOS. Unfortunately I was unable to find out any version for Linux. Discouraging for me as I am a regular user of Ubuntu
According to Amazon , Chime will soon be available through APN Level 3 partners and Vonage. With availability scheduled for the second quarter of 2017, Level 3 will add Amazon Chime to its suite of unified communications and collaboration solutions, providing enterprises with another powerful solution to help simplify and enhance communications.
