How can I fix call connection problems for my magicJack that is connected to a router?

If your magicJack is connected directly to a router, try the following troubleshooting steps:

  • Reboot or restart your router.
  • Make sure the phone and network cables are securely connected by unplugging and plugging the cables back until you hear or feel the connector lock in place.
  • Use a different ethernet or network port on the router.
  • Cords and cables can get worn out or damaged without any visible signs. Connect a different phone cord or ethernet cable.
  • Disable SIP ALG on your router. This is enabled by default in most routers. However, it is known to cause conflicts with external VoIP devices. For more information on how to disable SIP ALG, click here.

Remember to reboot or restart your router after each troubleshooting step to make sure any changes made are applied correctly.

What issues can SIP ALG on the router cause?

There are various ways SIP ALG can impact VoIP service. These often happen without the user knowing and can include:

  • One-way or no-way audio, intermittently or consistently
  • Inbound or Outbound calls fail to connect
  • Audio cuts out completely while on a call and doesn’t return
  • Phones ring and can’t be answered
  • Phones do not ring when called
  • Calls go straight to voicemail for no known reason
  • Faxes do not complete

Disabling SIP ALG on the router may help resolve the issues above. These are the general steps to change this setting in most router models:

  1. Login to the router’s user portal
  2. Navigate to the Advanced Firewall settings
  3. Ensure that SIP ALG (Application Layer Gateway) is disabled

Refer to the router user manual for specific steps on how to disable SIP ALG or contact your Internet Service Provider for assistance.

Note – SIP ALG does not cause problems such as static, echo or poor audio quality, these are generally due to network (Internet) connectivity issues.

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

Why does magicJack restart when I try to place a call?

Some computer manufacturers do not provide fully powered USB ports on their computers. Please try using a powered USB hub to increase the power generated to your magicJack.

Why do I get a fast busy on incoming calls?

Please make sure your telephone is not a rotary telephone. These telephones require a higher electrical throughput and will not work with the magicJack.

Why do I hear static on my calls?

Static on calls can be caused by numerous factors and can 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 download speed of 5mbps and minimum upload speed of 3mbps. 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  - request assistance with opening ports 5060 and 5070 on your router/modem. 

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

Why does my telephone not ring on incoming calls?

If you see you are receiving an incoming call, but your telephone does not audibly ring, first verify proper telephone operation:

  • Make sure the ringer on your telephone is in the ON position
  • Make sure the ringer volume is in the proper position
  • Ensure the phone cord connected to the base unit with your magicJack is no longer than six feet.

If your telephone still does not ring, please try connecting a different phone to your magicJack device.


If basic troubleshooting fails, this may indicate that your magicJack device’s firmware needs to be updated. Please see this article for further details.
