Make Free Calls on your iPhone with Google Voice and Fring

If you have a Google Voice account, you can make free VoIP calls on your iPhone. You’ll need to sign up for an account at Gizmo.com and download the free Fring app for your iPhone, but after that you’re done. You can make free outgoing calls to (up to three minutes) and receive unlimited incoming calls through Google Voice.
Hit the jump for instructions.
Ingredients
To do this you’ll need the following:
The following are optional but will optimize your experience (though Apple will hate you for it):
- jailbroken iPhone
- Backgrounder
- 3g unrestrictor
Sign Up for Gizmo
All you need from Gizmo is the VoIP part of the puzzle. You don’t need to download the Gizmo desktop client, but you will need to change some of your settings.
When you’ve signed up for Gizmo, login to your account and turn Google Voice on. Add your Google Voice account number and you’re set. On your way out, be sure to grab your Gizmo number, which is two headings below in the Account Overview section. You’ll see a heading called SIP Number. Copy it. We’ll need to add it as a phone in Google Voice.
Set up Google Voice
Navigate to your Google Voice settings and click on the phones tab. At the bottom of the tab is an add another phone link. Click it and select Gizmo as the phone type from the drop down menu.
Once you’ve added your Gizmo number, it’s time to open up Fring on the iPhone.
Set Up Fring
Open up your Fring app and click on the SIP selection in the Add-ons menu. Use the Gizmo option to login to your account.
Always Available
Fring now has push notifications so you can be notified when someone is trying to reach you. It isn’t the most reliable way to take incoming phone calls, but it’s the only way for an un-jailbreaked iPhone to handle incoming calls without having the Fring app open constantly. So this system isn’t dependable for switching to VoIP just yet, but you can make 3 minute calls for free and have your friends call you back for unlimited interaction time.
Either Way, a Smart Move
Using this system of Google Voice->Gizmo->Fring will help you cut down on your minutes, and it’s just the thing to keep you connected when you’ve run out. Jailbreaking your phone allows you to keep Fring open in the background to receive calls, and it also lets you wander off of wifi. Using the 3g network for VoIP means you can lower you minute plan to nil. All you need is data. Isn’t that a Beatles song?

How do you verify the Gizmo phone through Google Voice?
I press the Connect button on Google Voice, answer the call on Fring, but then Google Voice does not recognize the numbers I press on the Fring dialer.
Any suggestions?

There is a(n old) video on fring showing SIM-less phone calls on (free) wi-fi.
What changed?

Great article, I’m sure Fring downloads are going to skyrocket.
I too would love some input about whether this will work for iPod Touch (and if so, which generations).
Paul, on September 7th, 2009 at 8:27 am
Tom, I had the same problem. I was able to verify by downloading the Gizmo application on the mac and verified it then.
Nate, on September 7th, 2009 at 11:34 am
The Fring client does not support DTMF (Touch tone generation), so there is no way to verify the Fring “phone” for Google Voice. It appears users have been asking for this feature for over 2 years, according to the Fring Forums. I even tried a tone generator applet and held it up to the iPhone, which didn’t work either.
How did you get this to work?
Michael, on September 7th, 2009 at 11:40 am
I found a solution. You must download the Gizmo desktop client and answer the Google Voice verification call from the client, which does support DTMF tone generation.

@Michael, Nate, Tom
You can make the call directly from Fring. You don’t need to initiate anything in Google Voice.
In Fring, just select the contact who you want to call and press SIP Call and you’ll be using google voice to connect.
Tim Cox, on September 7th, 2009 at 12:35 pm
@ Tom,
What we are talking about is the initial call from Google Voice to the SIP # when you add the Gizmo service to the Google Voice account.
You also need to disable the Call Screening and Call Presentation features, as the Fring client can’t generate the tones to put any incoming calls through.

Cool. I used on an iPod Touch connected via my wifi to call my mom and wish her happy birthday.

I just got this hooked up, and finished my first phone call, of about half an hour. I few thoughts;
- While the sound quality is good, it stalls everyone and a while, especially as the call went on.
- My iTouch (second gen) slows down considerable when fring is active. I just re-booted, which will hopefully help performance for the next call.
- If a call comes in when the fring app is open it works fine, when the app is closed, fring alerts me to a call … then puts me in a (useless) text chat.
Over all this is a promising technology, which with a little refinement will be very useable.

I’ve done this 2 days ago however incoming calls are not unlimited the Gizmo SIP system will cut the conversation after 3 minutes. It is written on Gizmo settings that only allows the incomin google voice call to 3 minutes.

Is GV and Fring only offers peer to peer free calls like all other skype, Vopium and Truphone or they offering free calling to landline and mobile phone ?
Yani, on September 8th, 2009 at 1:34 am
i have read abt it long back, and it works… http://bit.ly/wgBVm

So after reading through the comments a few times I finally got everything working.
While I was setting this up I also found out you can send free SMS messages with Google Voice and either GV Mobile or Voice Central.
So I guess the only question left for me is: Is there a program that can do both?
I don’t know if GV Mobile or Voice Central are supposed to be capable of calls like Fring is but I wasn’t able to get either to.

this works great but cant verify thru google voice not picking up the code to verify number
david, on September 9th, 2009 at 10:57 am
I have downloaded the desktop client but the verification call is not ringing on my desktop (it did on my iphone). Can anyone help?
Ram, on September 9th, 2009 at 11:53 am
you can download the desktop version, but you can also call your iphone, answer and then click “back” which will give you the option to enter the keypad or any other tab while staying connected. I believe this should work (I used the desktop version before I discovered this myself)
awesome little trick. it kinda blows my mind trying to figure out everything thats happening, so props to you for doing the brainwork.
Brandon, on September 11th, 2009 at 3:45 am
On second thought, that probably won’t work, as the Fring keypad still doesn’t send DTMF tones. therefore you would still have to use the desktop client.
sorry, I tried.
I couldn’t have found this any sooner though, I have like 5 mins left on my account for the next 5 days.
Brandon, on September 11th, 2009 at 4:19 pm
Incoming calls don’t work for me – fring just opens a text chat for some reason.
Karen, on September 16th, 2009 at 11:54 pm
Salam how are you
abdo, on September 22nd, 2009 at 1:20 pm
Everything works. Dont worry about the Dtmf tones, all you have to do is go change your settings in google voice account and turn off call screening and call presentation. When you first have to activate the phone though go to gizmo site and foward the call to a regular phone and from there press the tone to verify.
It all works if any of you want to see me do a youtube video on it ask or check to see if one is on there already.
ren, on October 3rd, 2009 at 4:26 am

connor, on October 6th, 2009 at 3:41 am
hey when u answer a call tho it says press 1 to accept the call however i dont believe this is possiple.is it?
connor, on October 6th, 2009 at 3:51 am
nvrmnd i disabled it
connor, on October 6th, 2009 at 4:01 am
There is no need to download the desktop client. Just go to the Gizmo site and have it forward all calls to your home number. (There are two settings to check: one for the forwarding and one for which number to receive the calls.) Then go back to Google Voice and have it verify the number. Your home number (or whatever you chose) should ring. Once you’ve verified, go back to Gizmo and turn off call forwarding.
Paul, on October 6th, 2009 at 8:31 pm
I want to know how i can receive call when people call my google number using fring. people call my google voice # on my fring and what i see two box cancel or accept and once u accept it on my iphone 3gs they ask me to press one i dont know how to press one when i accept it,please can u tell me how to go about it thanks
yvonne ihekaba, on October 30th, 2009 at 5:40 pm
@yvonne: turn off call screening and call presentation in google voice settings
Vadim, on October 30th, 2009 at 9:58 pm
Might as well change this blog post. Google bought Gizmo5, and they’re not taking any new subscribers now.
