A SIP Stack written in Rust

WIP This is a work in progress and is not yet ready for production use.

A RFC 3261 compliant SIP stack written in Rust. The goal of this project is to provide a high-performance, reliable, and easy-to-use SIP stack that can be used in various scenarios.

TODO

• Transport support
  • UDP
  • TCP
  • TLS
  • WebSocket
• Digest Authentication
• Transaction Layer
• Dialog Layer
• WASM target

Use Cases

This SIP stack can be used in various scenarios, including but not limited to:

• Integration with WebRTC for browser-based communication, such as WebRTC SBC.
• Building custom SIP proxies or registrars
• Building custom SIP user agents (SIP.js alternative)

Why Rust?

We are a group of developers who are passionate about SIP and Rust. We believe that Rust is a great language for building high-performance network applications, and we want to bring the power of Rust to the SIP/WebRTC/SFU world.

How to run

# the sip phone will serve at: YOUR_NETWORK_IP:25060
cargo run --example client

Make a call to sip:YOUR_NETWORK_IP:25060 from another sip client.(e.g. linphone)

Run with OpenAI realtime voice model

1. apply for OpenAI API key
2. set the API key in the environment variable OPENAI_API_KEY

export OPENAI_API_KEY=your_openai_api_key
# or moddify the .env file

cargo run --example client -- --realtime --prompt "What is the meaning of life?"

# or prompt from the text
cargo run --example client -- --realtime --prompt prompt.txt
