Static on calls can be caused by numerous factors, but can usually be resolved by one of the following:
Swap out phone hardware to verify the issue isn’t with the phone itself.
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 sourceforge.net/speedtest/.
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.
