I am implementing Audio/Video call with SIP js and Astrisk server in React JS.I was successful on creating the WebRTC Audio/Video calling. But I am facing an issue with storing the Invitation or Session Object for SIP js. Because Circular JSON data can't be stringed to store.
Assume someone has started calling and the other end got notification of calling and in that case if the page refreshed or reloaded I am unable to recover the call session to take any action(answer/ decline)
