Meshenger

Meshenger allows voice and video calls without any server or Internet access. Simply scan each others contact QR-Code and call each other. This works on most networks, e.g. at home, in community networks or at work.

Meshenger exchanges the contact name, public key and MAC/IP/DNS address via QR-Code. By default, only a MAC address is transferred as address and then used to create an IPv6 link local address to connect to the contact. This does not even need a DHCP server. The exchanged public key is used to authenticate/encrypt signaling data to establish a WebRTC session that can transmit audio and video.

• uses IPv6 link local by default • encrypted communication • encrypted database • database backup • night mode
