matrix-sip-bridge

A bridge between Matrix and VoIP via SIP to answer (and in future make) phone calls from Matrix.

Current state of this project

I am planing to rewrite this bot in go, soon™ The current NodeJS codebase is now considered deprecated and won't receive any future updates.

Current roadmap for the new rewrite:

• [ ] Support for SIP over port :5060 and :5061 (instead of requiring the SIP server to expose a webrtc/websocket endpoint)
• [ ] Receiving/making audio calls
• [ ] Displaying who is currently calling 👀
• [ ] End-to-End Encryption (e2ee)

Please be aware, that this is considered early stage software

There may or may not be a lot of bugs and breaking changes. But especially because of this, you will be able to influence how this project continues to develop.

Feel free to file issues, ask questions, provide feedback, hang out in the official matrix room or contribute some code - or whatever! 😊
