After spending many hours with tech support and my own time, here is the recipe for magicJack to work on DIR-655 when directly plugged into the router d-link DIR-655:
step-1:
--------
sign on to your router.
type this in the URL 192.168.0.1
Sign in with admin password
step 2
-------
Identify the ip address of your magicjack plus when plugged into your router.
You may need to log in or log out and plug in and out the mj multiple times to identify the ip address of mj+ (there is no name associated with Mj+ device when connected)
Once you have identified the ip address process to step 3
step 3
-------
Reserve the IP for magicJack ie
Click on setup network
scroll down to section Add DHCP reservation`
Select the ip identified in step 2
Assign the name magicJack to this IP
Click Save.
From now on when Mj+ connects to the router, it will have this ip address
Step 4 set port forwarding to 5060,5070
-----------------------------------------------
Click on advanced tab
Click on Port fowarding (second option on the left of screen)
Fill in the following values:
Name magicJack
Ip address (select computer name magicJack) then click on << to populate the ip address field- (You may also populate this field manually)
UDP =5060,5070
schedule Always
Inbound filter Allow All
Click Save Settings
Step 5: Uncheck SIP
---------
Go back to advanced.
click on Firewall settings (on the left)
scroll down to Application Level settings
Uncheck SIP
Save
Reboot the router.
After the router is rebooted, this should work
This settings works for me for mJ+ plugged directly to the router
