  2. Start up your magicjack. Leave the softphone on the screen.

Running MagicJack as a service

Frank Zappa for put this procedure together. Thanks Frank!!!!

Now magicjack runs as a service, is completely invisible, starts up automatically on boot, and I don't need fast-user switching enabled, thus it takes up no memory caused by virtual desktop programs or autosizer, and has 0 focus problems.

Here is my current step by step to get this setup ->

1. Download rktools.exe

2. Extract it.

3. Create a user account named "magicjack", temporarily assign admin privilege. Also create a password for this account.

4. Login as “magicjack”, and install the magicjack under this profile.

5. Install the magicjack as a service, using the tutorial

After you create the service, if you export the registry value from regedt32.exe, it should look similar to this ->

Windows Registry Editor Version 5.00



"Application"="c:\\Documents and Settings\\magicjack\\Application

Note: the ImagePath string value is really something like "c:\Program Files\Windows Resource Kits\Tools\srvany.exe"

6. Delete the two cdloader entries for MagicJack in the registry. Using regedt32.exe, logging in from both of your user accounts, delete this entry from ->


7. Change the magicjack user account to be a user account instead of an admin account.

8. Enjoy!

Notes: Now, when I did this the magicjack service still wouldn't start, so I went to Control Panel->Administrative Tools->Services->MagicJack and tried to start the service from there, but I got this error ->

"Could not start the service on Local Computer. Error 1069: The service
did not start due to a logon failure"

So, I went to the log on tab (still in the magic jack service tab) and put in the password, and everything works beautifully!

Spoofing Caller ID

I just noticed that Stewart posted how to spoof the caller ID from your MagicJack line. Read the post here. I was able to use the perl script to set my outbound caller id to my grand central line. This is great until MagicJack has numbers in my area code!

You can also set your caller id to any other number to fool your friends!

New unofficial magicJack forum now open

A new forum has been open for magicJack users to get unofficial support

Many of the previous posters from the original magicJack forum have now joined and can help you with any issues or questions you have about the magicJack product

MagicJack SIP info

MagicJack uses standard SIP, so once you determine your SIP information (username/password/etc), you can use your MagicJack service with any standard VoIP device.

The easiest way to uncover your MagicJack SIP information is to use Fiddler.

Since all MagicJack passwords are very simple, you could also very easily brute force them using cain, although this technique is a bit more involved than using fiddler.

There are a few other techniques you could use as well, but most of these involve exploiting some of the gaping security holes in the MagicJack, and should probably be discussed offline...

For Example:

If your magicJack is pointing to the following proxy:

and you want to change it to:

Ping to get the IP address

Now just add the folowing entry to your windows hosts file

Note: magicJack has many proxy servers to choose using the following naming order:

Changing and removing skin files to reveal more features in MagicJack

The easiest way to see the hidden features in the magicjack is to rename or move the big.skn and small.skn files in the mjusbsp directory to a temporary folder and restart magicJack. Other SJPhone skn files can be used with magicJack as well but will not reveal any more features.

Using other Softphones with MagicJack Hardware

MagicJack hardware can be used with a host of other softphones. Tigerjet has a nice list of software to make it work. Remember to turn off the magicJack software first before attempting to use another softphone.
