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.
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] ProxyUserName=username ProxyUserPassword=FAB16g9XNa ProxyDomain=a.vonim.com ProxyPort=10000
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
