This is a basic web app that lists some typical SIP flows, showing a call flow diagram for each. Originally done as a project to get used to working with Mermaid but it's potentially useful as a tool to learn a little SIP as well.
The code is rough and ready, you've been warned.
The project was bootstrapped via
create-react-app. This means you
can clone the repo, npm install then npm start to run a local version.
