MagicJack is a new way to make and receive phone calls through your computer's Internet connection. A small USB adapter plugs into your PC and the phone plugs into the adapter piece. Since you are making calls through Voice over Internet Protocol the connection is subject to data packet errors and other delays that may make your phone calls difficult to hear. The best way to improve your MagicJack connection is to improve your Internet connection. Use one of several methods to do this.
Call your Internet service provider and upgrade to a faster Internet speed. MagicJack may improve simply by subscribing to a faster download/upload speed.
Plug an Ethernet cable from your computer directly into your modem when you want to use MagicJack. Wireless Internet is convenient, but it decreases call quality.
Hold down the keys "Ctrl," "Alt" and "Delete" on your keyboard. This will bring up the Task Manager.
Click "Applications" and then right-click "MagicJack."
Choose "Go to Process" and right-click "MagicJack" again.
Click "Set Priority" and choose "High" or "Above Normal." Click "OK" and then start using MagicJack.
Close down other unused software programs while you are using MagicJack. Pause any uploads or downloads that are currently running. Multiple programs slow down your speed and cause faulty phone connections.
