i have had magic jack for about a year. when i first got it it took me about a week of constantly chatting on line to get them to correctly configure their network so that i could get dial tone.
then magic jack worked good for about 2 weeks. i then start hearing echoes and am constantly hearing the voice cutting out to the point that i cannot understand what is being said. i did pay for the extended service.
i have had it with majic jack.. i thought about trying to get another jack or loading magic jack onto a different computer but after reading all these negative reviews i think ill just cut my losses and move on.
