Hello Rebyroo, cell over WiFi generally will not work well on satellite due to the high latency (ping). There is no remedy for the latency because the satellite is so far up in space.
Hughes offers Huges Voice as their VOIP but it's not for use with your existing cell phone. $45/month if I remember correctly?
We canceled Hughes Voice when we upgraded to Gen5 as advised by our local tech. Wi-Fi calling worked great for the first couple of months with the Gen5 but recently we've been experiencing all the problems many have expressed in this thread. Very frustrating because we can hear the person on the other end just fine. Texting works well too.
I tried to hook up the T-Mobile wifi extender and after wasting a full day got a somewhat straight answer from Hughs.. The ports used by T-Mobile are closed on the Gen 5, I can only assume so that we are forced to buy their service? Odd that my wifi calling worked so well when I first got hooked up and not so well now, kinda don't believe it is the ping since it worked fine for a month!!
