Why do I hear static on my calls?

Static on calls can be caused by numerous factors, but can usually be resolved by one of the following:

Switch Phones

Swap out phone hardware to verify the issue isn’t with the phone itself.

Change Ports

If your magicJack is plugged into your computer, switch the device to a different USB port. If your device is plugged into a router, switch the ethernet cable to a different ethernet port on the router.

Test Your Network Connection

Call quality issues can be caused by low internet speeds or unstable network connections. We recommend using a broadband-equivalent (or better) connection with a minimum upload speed of 128kb/s.

You can test your internet connection speed at

Change Cables

Try replacing the cables associated with your configuration:

  • Ethernet cable
  • Phone cable
  • Power adapter (if available)

Contact Your Internet Service Provider

Contact your Internet Service Provider and request assistance with opening ports 5060 through 5070 on your router/modem.

If you still experience issues after completing the above steps, please contact our Customer Care team for further assistance.
