My users are from a web application using JSSIP. They each have a sip trunk account, which could be from any provider.  JSSIP would connect to Kamailio's websocket server passing the SIP trunk credential information and Kamailio will relay it to that specific sip trunk provider?

Is there anyway that I could use Kamailio as the middleman? Is it a combination of dispatcher module and websocket module? 

Thanks!
