KDE's Kaidan Messaging App Plans for Encrypted Audio and Video Calls
The Kaidan team announced a few days back that they plan to implement encrypted audio, video calls and some associated features. Kaidan will receive a financial grant from NLnet of Europe for this work.
The primary driving factor of this development is the demand. Recently, many XMPP protocol chat apps introduced audio and video calling. The users are moving away from chat to calls for ease of communication and other benefits in XMPP.
