We are a bit unique. We are 100 miles in the Canadian wilderness. This satellite.computer is our link to the outside world. I have VOIP telephone where I can place calls out but cannot receive calls. That works pretty well. I also use skype which works somewhat OK but is unreliable at times.
I have downloaded JITSI and it looks great. My parents downloaded JITSI. We are online. Instant messaging works great. Phone has failed completely. If I try to place a call to my parents on JITSI it rings a couple times. Then when it is answered on the other end it immediately disconnects and I get error message " ICE failed"
JITSI looks like a wonderful program and I know there are many settings to potentially modify. Since VOIP and skype will work in our situation, I'm hoping someone might have some ideas to try. We are a satellite connection but the other stuff works so I'll try any thoughts you folks might have. Thank you so much in advance for your input. Have a great day,
