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.

There’s def web clients already out there. I’ve seen satchel, just haven’t come across an actively developed one.
Jssip is a neat library but not a client: https://jssip.net/
Twilio also has a web client.
Taking a cursory search of WebAssembly for voip shows some activity:
Webrtc is a little old and using webassembly to introduce other codecs isn’t entirely new or novel: https://cloudtweaks.com/2020/08/deep-customization-webrtc/
Blazer allows using webassembly to make calls from twilio: https://www.twilio.com/blog/making-phone-calls-from-blazor-w...
Another neat use for webassembly and audio is audio production say for podcasts with multiple callers that makes editing a bit easier. https://superpowered.com/js-wasm-overview
Noise cancellation and other dsp effects are something webassembly can meaningfully help with. https://news.ycombinator.com/item?id=30568164
