How to Set Up Vonage on Your iPhone

July 27, 2009

There are many options when it comes to making VOIP calls over WiFi or 3G with your iPhone. Many prefer Skype but here in Canada not only are we blocked from downloading the app in the iTunes store (though there are ways around it) but there are no SkypeIn numbers available in Canada. So this plus the fact that I already use Vonage for my home line makes it the best option for me. There are also many SIP applications available for the iPhone either through iTunes or Cydia. The only catch is that Vonage wants you to pay an extra $12 a month to get a “softphone” added to your account, and it gives you another number. Since I don’t need an extra number, nor do I want to put more money into the hands of Vonage I did some digging around and found a solution.

As it turns out any Vonage line can be used as a SIP line. All you have to do is find out the domain and your encrypted password. Doing so is actually quite the simple process. Enter the following into your browser, making sure to replace the parts in bold with your account information.



Update 09/07/2009: Unfortunately our friends at Vonage have taken down the above link. As of now I know of no other way to obtain your encrypted password, I will try to find an alternate method and when I do I will put up a new post.

You’ll get a page with a bunch of information on it, the part you want to pay attention to is at the top:

[SIP 2.0]

This contains all the information you need to register your account on Fring or SIAX. In the past I used SIAX however they decided one day to make it so you had to purchase the software, which defeats the purpose of Jailbreaking your iPhone (in my opinion). So now I use Fring, which can be downloaded for free in the App Store. Configuring SIP in Fring was a little less than straight-forward for me, so here are the steps to set it up:

Create an account or login to your existing account
Go to More then Add-ons
Select SIP, then Other

Fill out the fields as follows:
User ID = ProxyUserName
Password = ProxyUserPassword
Proxy = ProxyDomain:ProxyPort

Now save those settings and try making a SIP call. If you don’t see the SIP option lit up on the Dialer pad then you may just need to wait a few seconds for it to connect to Vonage

  1. not only is the config cgi not working, but neither are sip connections created with information from the cgi, or the alpha Vonage Talk application.

    the Vonage alpha page say that the testing is over and if you want to use your pc and your vonage number, upgrade (?) to to vonage pro.

    the ? is there because with the new $25 plan, going to pro, looses the world calling feature, so is it really an upgrade?

  2. Yes I had this working for a few months and it stopped in Sept. I hvae been trying since to get it working. Vonage companion still works but vonage talk is broke. Anyone wants to try and work on this let me know. I wouldl ike to help.


  3. I noticed this stopped working for me on Sept 4 @ 11:36 central. Vonage talk is broke. Vonage Companion still works. Traffic is encrypted and using some random xml pages. Anyone wanna work on this let me know.


  4. Hi:

    Vonage companion only works sporadically for me, not reliable so far. Any tips are appreciated.


  5. Try this iPhone app. vOnGo (Vonage on the go)

    It lets you use your Vonage world plan from your iPhone with no recurring charges. Good alternative to Vonage Mobile.

  6. @Soundy – I was actually very disappointed by Vonage Mobile when it came out. The fact that you need a separate account to use it is absurd (I already pay $20/m for unlimited and hardly use it). On top of that it’s not available in Canada. I was so pissed off I called Vonage and cancelled my account. Screw them.

  7. I just bought the iPhone and everyone was telling me about all these apps and vonage mobile one of them….no way I will have two separate accounts and I will also cancel the service since I hardly use it…Magic Jack here I come!
