Depends on where you are.
I’m in the Midwestern United States now, where summer is often pretty frustrating due to the high humidity. But I’m originally from Phoenix, where I really enjoyed summer (in the shade), because I love the feeling of warmth soaking into my bones, and I never got sweaty.
I run those calls through my own phone system, which I host on a system in my basement. There are a couple main options out there, I used FreePBX for a while but now I’m using 3CX. They don’t require a ton of computing power-- mine runs on a virtual server inside a larger system, but you could run one off of an inexpensive thin client from eBay if you wanted to.
I get my phone number from VoIP.ms, which is pretty inexpensive and has worked well for me for years.
For a phone, you can either use a soft phone (an app on your computer or smartphone), or use an older IP phone off eBay (which is what I do since I also have a Plantronics wireless headset that connects to it).
It’s pretty easy to get started, but you do need to make sure you’re configuring everything correctly since selfhosted services can open up security holes in your network if you don’t know what you’re doing.
This is why I always record calls with major corporations when I’m talking about money. I’ve never had to actually resort to sending them recordings, but I have used the “Well, every call made from this phone is recorded, so I can go back and pull the recording of what I’ve been told if you don’t have it in your system” line a couple times.
Unfortunately the amount of delta-V you’d need to boost it to a parking orbit of some kind, or to the moon, would be deeply impractical. And it doesn’t have the shielding required to support any sort of deep space habitation.
I’d love to see some or all of it returned to be displayed in a museum, but it would probably be more expensive to do that than it was to build it in the first place. The vehicles to return it in whole or in pieces simply don’t exist right now, and on-orbit disassembly would be incredibly difficult and dangerous for astronauts to carry out.
