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.

Works much 10X better on ATA than the crappy USB interface.
-with the magicjack sip information, you can put it into your old vonage modem box (ATA) and use that box instead of the little magicjack usb plug???

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...

Tutorial on how to see the sip info on the MJ

OK Guys, Try this.!

1) …and download the pmdump but don’t run it but just place that .exe file on your desktop.
2) Follow the guide and run it as described while magicjack is plugged in.
3) Once you run it, it will place a file on the desktop.
4) Go here http://www.hexworkshop.com/ and download the “Hex Editor”.
5) Run the hexEditor and drag and drop above file in.
6) Go to Edit menu and select find -> text string value “ProxyUserPassword”, “SIPProxyURI” (this will look -> SipProxyURI : sip: 207.155.164.198 :5070) . your proxy user ID is, EyourPhoneNumber01

7) After noting down all above go here http://www.dslreports.com/forum/r21209178-magicjack-sucks and determine according to IP address (sipproxyURI) , what city you are located. If U don’t find that IP here please google it. If U find more reliable site please post for all.
Then modify Ur proxy like this: proxy1.yourcityname.talk4free.com:5070

8) Now you are ready to use your own device.

You have Username, Password and the Proxyserver.

If you use Linksys PAP2 , its like this..!

Username and password as above
sip port: 5070
proxy: proxy1.yourcityname.talk4free.com:5070
register: yes
make call without reg: yes
answer call without reg: no
register expires: 3600
display name: your phone number

MagicJack sniffing the SIP info using pmdump utility

This is simple and not so simple. You MUST be quick to get the SIP information you need. Here are the steps.....The registration password is in your computer memory for only a short time.

So lets get started!!!

1) First, get pmdump utility from here... http://www.ntsecurity.nu/toolbox/pmdump/

You will need to run the above program under DOS command line. e,g just put it under c:\

Run it like this..

C:\pmdump PID outputfile.txt

You can get the PID by doing the following...

c:\pmdump -list

As soon as you see MagicJack.exe in the list and its PID, use its PID. e,g when you run the command above, you will see lost of PIDS including a number like this...
1809 - MagicJack.exe

therefore
1809 is your PID.

so run this command quickly
C:\pmdump 1809 outputfile.txt

Changing Proxy Servers on MagicJack

Now that magicJack has implemented a DNS entry for the proxy server address, it is possible to change the proxy server you use. This can be done in the by pointing the proxy address in the windows hosts file.

For Example:

If your magicJack is pointing to the following proxy:
proxy1.nashville.talk4free.com

and you want to change it to:
proxy1.newyork.talk4free.com

Ping proxy1.newyork.talk4free.com to get the IP address
67.106.135.70

Now just add the folowing entry to your windows hosts file
67.106.135.70 proxy1.nashville.talk4free.com

Note: magicJack has many proxy servers to choose using the following naming order:
proxy1.{city}.talk4free.com

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!


rewrite of the perl program to C#. 

Anyone used www.magicmojita.com for fixing the callerid problem with MJ
