I've had my MagicJack for 4 months now. Im using it with the last generation of non uni-body macbook pro 15". i'd say 90% of the time i am plagued with choppy voice issues either sending and/or receiving. sometimes calling back helps. but its so unreliable for clear communication that i am now considering going back to a land line. there has not been any viable solution to this posted anywhere. magicjack support is also of no help.
I have been using MJ with my Mac intel OS 10.5.6 Macbook since July of 08 and my service has improved greatly, I would say 98% of my calls are good now. I am connected wireless with a Panasonic Dec 6 cordless phone. How is your internet speed?
