It's just an IP network; it doesn't know what the data packets it's carrying are doing. So any VoIP phone service (Ooma, etc.) should work fine. I would confirm with them, though. It's probably technically possible for them to block VoIP but I don't know why they would do it.
Some cell phones will use WiFi when it is available, like Google Fi phones. In that case you would not need a VoIP carrier. Your cell phones would just work. That's the theory anyway.
Starlink satellites are a LOT lower, like 350 miles above earth, while HughesNet sats were 22,000 miles. That's why there's a big difference in latency. I have no knowledge of bandwidth and throttling on Starlink.This sounds great. Years ago, I had HughsNet, but the latency was bad. And they were quick to throttle with seemingly normal usage.
It doesn't sound like Starlink has these problems
Yeah. The geosynchronous birds are a long ways away because that's where the orbit has to be for the numbers to work. Aka a Clarke orbit. That's why, for example, you see awkward pauses in conversations between network news people at home base and people in the field. But those birds stay in one place. LEO (Low Earth Orbit) puts the birds much closer but they are always transiting overhead, so the connections have to be handed off as one bird fades and another is ascendant.
