all the other additions wouldn't amount to a hill of beans if the ONE MOST IMPORTANT thing isn't changed FIRST
Improve Call Quality
what's all the other choices matter if the call sounds like crap, with sputter, beep tones, crackel, echo, missed words form lost data flow ... etc
sometimes it works well, but not all the time, even with my ISP giving 15MB download and 2.5MB upload speeds... so, it's the MJ servers themselves slowing down when more people are using it.
Late in the night, early morning it seems better, but during "prime-time" like 6: PM to maybe around 11: PM very choppy sound
during 2: PM to around 5: PM a little better but still sputter sometimes, but later at night and almost earlier in the morning hours it's better, so it's MJ's bandwidth not being able to keep up with demand.
Forget the ATA idea, they're basing their company on ads and won't allow that to change, it needs a computer to use, and be glad they don't make the window force in-front ... YET! .. the ads haven't started yet either , because they're actually using this forum to iron out the 'BUGS' that makes it unsecure to hacking and not showing the ads, as well as the thing not working at all sometimes ...
And you can't expect dedicated customer service 24/7 for just the $20.00 / year, until the ads start to generate cash in their pockets.
SO... if you really expect they'll give you all the other ideas, before making it sound good first, and stop the hacks, you're dreaming.
I'm using it as a back-up, not as a replacement for my home phone.
