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!

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...

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.
