We have a PBX that doesn’t support websockets .

But we want a PWA webaapp ctxSIP that uses sip.js to work .

Due to its not SIP generic do we setup like this

PBX ßà Kamailio ßàwebapp

Im looking  for developers for android build via react native or ionic framework but not sure what solution/archtectiure

Question. Does Kamailio register the SIP user/pass on the Kamailio server meaning it keeps it registered. And thus the ctxSIP client app just handles the pass thru for that connection.

What about RTP do I need a separate handler for that.
