Free calls from iPhone to Landline

Q: Can I make free calls from my iPhone to landlines? A: Yes. Q: How can I do that? A: I succeeded to install a SIP VOIP iPhone client (Siphon) on my 1.1.4 iPhone. Then I configured my VoipBuster SIP account on that client. The result as of today is that I can call any landline in my country for free. What I did is a VOIP call over WIFI (VoWi). Check the rates HERE. Q: That is cool, are you willing to tell me how you did it? A: Sure, some geeky skills are needed because you have to edit in the filesystem. Therefore I recommend WinSCP to connect and edit the files, but if you a Mac OSX user, just get your favorite tool. Okay here we go:

1. You need a jailbroken iPhone with OpenSSH installed. I have tested on a fw 1.1.4 iPhone

2. Get the Siphon software from repo http://sip.free.fr/releases/rep.xml with installer.

3. install Siphon

4. Add the following line in /etc/hosts file: 194.221.62.198 freephonie.net

Because Siphone is hardcoded to connect to freephonie.net, you have to provide the IP address of the SIP server from VoipBuster. (just ping sip.voipbuster.com for the correct address)

-------------EXAMPLE /etc/hosts----------------------------

# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
194.221.62.198 freephonie.net

--------------------------------------------------------

5. Change the /private/var/Applications/Siphon.app/accounts.xml file with your voipbuster username and password. In some way, the account information will lost in Siphone when you change the account information.

-----------------EXAMPLE accounts.xml--------------------------------------
nat
NO
password
my_voipbuster_password
server
freephonie.net
stundomain
stunserver
timeout
1800
username
my_voipbuster_username

---------------------------------------------------

6. Start Siphone and Hit the SIP button. If the SIP letters lits blue than congratulations! You can make your free calls now. Dial a landline number of your home like you dial a international number. [Landcode+YourHomeNumber] Then Hit the CALL button....Is it ringing??? oooh what a exitement.... it is ringing, pick-it-up!

Known issues:

- As of today, you have to use the headset to hear something. And you hear only the left ear.

- I am investigating how someone can call my iPhone. any suggestions how to do that? I don't have a phone number from voipbuster.

- I haven't try to use other SIP VOIP providers than voipmaster, but it should work.

- Next step is to try to make it work over GPRS or EDGE in stead of WIFI. Please post your results here.
