pushpesh47/sys-sip ? reverse-engineered prompt

Build me a Linux desktop SIP calling app that feels modern and easy to use.

I want a simple dialer where I can type a phone number or SIP address, make and receive calls, mute my mic, see call status, and keep the app running in the system tray. It should also save my contacts and call history so I can search, redial, and see missed, answered, and failed calls later.

Please include support for adding more than one SIP account, with a way to switch between them and connect or disconnect each one. I also need a setup flow for Jio Fiber that can get the SIP details from the router using an OTP, plus a manual setup option for other providers.

Make it work well on Linux, use a clean Qt style interface, and store data locally so it feels like a real desktop app. If you need to check current docs while building, go ahead and look them up.
