I’ve done a couple of cross continent moves now with movers moving my stuff, and most things were fine - drives if they’re powered down are generally safe. The only thing that has happened is my graphics card power cable had worked itself loose and the card burned out because of it. CPU fans, hard drives, power supplies were all fine.

I’d say after you get to your destination check all the things - especially cables would have saved me a 1080 (it worked for over a year so it really wasn’t obvious from a visual inspection).

Is JellyFin listening on localhost? Try changing its binding to 0.0.0.0 instead. Localhost is not available off the local machine, so I’m not sure what you mean by ‘let devices from local host access the pc’.

I haven’t seen any business VOIP plans that are unlimited outbound, and no matter who you use you’re paying for calls to/from the PSTN. I use CallCentric - they have plans for 120/500/1000/2500 minutes to US/Canada. You need to pay for the line and e911 service, and yes they give you instructions on how to connect to many devices.

I think your total would be $40 or so per month for the line (unlimited inbound) and 2500 outbound minutes.
