# Meshenger

True P2P voice- and video phone calls without the need for accounts or access to the Internet. There is no discovery mechanism, no meshing and no servers. Just scan each others QR-Code that will contain the contacts IP address. This works in many off-the-grid networks such as community mesh networks but also in company networks or at home.

Features:

- voice and video calls

- no accounts or registration

- encrypted communication

- database backup and encryption

- add custom addresses to reach contacts

Limitations:

- no calls through firewalls / NAT borders

- no calls after MAC / IP address change

Known Issues:

- calls via phone hotspot are [buggy](https://github.com/meshenger-app/meshenger-android/issues/133)

An alternative is to directly translate the values in [strings.xml](https://github.com/meshenger-app/meshenger-android/blob/master/app/src/main/res/values/strings.xml) and then to create a pull request or send it via Email.

## Documentation

Meshenger connects to IP addresses in a true P2P fashion. Contacts are shared via QR-Code. They contain a name, a public key and a list of MAC/IPv4/IPv6 addresses or domain names. By default, only a single MAC address is transferred and used to create an IPv6 link local address (among others) to establish a connection. This does not even need a DHCP server. The exchanged public key is used to authenticate/encrypt signaling data to establish a [WebRTC](https://webrtc.org/) session that can transmit voice and video.

Details can be found in the [Documentation](docs/documentation.md) or in the [FAQ](docs/faq.md).
