fonoster VS SIP.js

OSS Alternative to Twilio

There's a service that's open source for full on features if that helps, here it is: https://fonoster.com/

You can probably use Twilio for this, but it's a paid service. The only alternative I'm aware of is Fonoster, but that's a JavaScript API - and I have no clue if it actually works.

I was looking at maybe trying to use a softphone to receive calls from an Android phone. Is there any way to do this? I'm looking at maybe trying something like https://github.com/fonoster/fonoster (self-hosted twilio) aswell.

You mean like https://github.com/fonoster/fonoster

TLDR; → Fonoster on Github

SimplePhone is a phone built using SIP.js that runs as a Docker container. Please see the documentation at https://sipjs.com/ to develop your implementation.

I found this library: https://github.com/onsip/SIP.js/releases

Because it's implicit, CJS creates a bunch of resolution issues with Typescript, to the point where if you want to code for the browser, you can't easily can't and have to either recompile with something like webpack to rewrite the module resolution, or add .js to all your TS imports, which already looks weird (you'd think you're importing the .ts files). sip.js has that issue.
