Hello. My name is***** can help you with your question.
The most common reason for this is that your Internet bandwidth is too low.
Bandwidth is too low. If you’re on a DSL line with 1.5Mbps down and 128Kbps up, your connection speed is just at the limit of what’s reasonable with magicJack, so long as nobody else on your network is attempting to stream video or upload anything. If you share your internet with other people in the same house, or you’re letting a neighbor leech your wifi, it’s possible that your calls will be not only choppy, but less likely to actually connect.
If that is not your situation, what I would suggest doing is turning off all your network devices and then turning them back on one at a time. Start with your modem, then your router, and then magicJack and try making an outbound call. If that does not correct the problem then either your magicJack device has failed or there is something wrong with your Internet connection that should be looked at by your Internet provider. Please let me know if this helps or if you still have questions.
