I have been using myMJ since December of 08, with no major problems but then my cell phone it's my main phone line. The sound quality problems were easily fix with the help of this forum. I found problems similar but I don't really know what you're talking about change change some numbers to 840 or 900. Really I don't know what these values are or where to find them. Making phone calls is really not a problem it seems to work other than the odd drop call.
My brother had a problem but it turned turned out along with high-speed make sure you're upload bandwidth is adequate, he couldn't be understood
Unable to receive calls and check voicemail
