WebRTC is an open source project from Google, and that’s great, but WebRTC is quite far from a complete SIP client, so in order to get an IOS/Android app to talk SIP to Asterisk, like REGISTER, etc etc, I would probably need either to build that layer, or use something already made.
Does anyone know of something in the open-source space that can do this? I’m thinking something like sip.js, but in a modern API format wrapping the mobile WebRTC framework.
I’m happy to do the top level UI and call management etc.
(Also I know about the commercial versions, they seem to only support their own services.)
