Do you have a Magic Jack Plus?
Do you get a message "Error 23" when you lift the phone hand set, instead of a dial tone?
Read on for a solution ...
This tutorial assumes that you can find your way around your router's configuration menus from a browser. Refer to your router's documentation to find out the specific IP address for your router and where the relevant options are.
Step 1: Find the MAC Address for the Magic Jack Plus
Like any Ethernet devices, there is a so called MAC address assigned to your Magic Jack Plus.
First, we need to find out the MAC address for your specific Magic Jack Plus.
This would be under the "DHCP Table" or similar.
The MAC address would be something like 6c:33:a9:xx:xx:xx.
This will be used in the next step.
Step 2: Reserve the IP address to the MAC address
Now, look for where you can reserve the IP address assigned to this MAC address. This means that whenever the router is restarted, or the Magic Jack Plus is unplugged from power, it will have the same UP address assigned to it.
Then we proceeed to the next step.
Step 3: Configure NAT to direct ports to the Magic Jack device
Now, go into where the "NAT" or "SUA" settings in your router are, and assign ports 5060 and 5070 to go to the IP address that you reserved
Make sure you save the settings after each of the above steps.
Now you should have a dial tone when you lift the phone's handset.
