SIAX dialpadI found this sweet little setup for getting Vonage to work on my iPhone the other day. I had looked into using Fring awhile back, which had the ability to add VoIP, but I discovered that it wouldn’t work with my Vonage Canada account. I have just a regular home phone setup with them and wasn’t interested in paying the $12 a month they wanted to charge for a SIP account.

Then I happened upon a forum thread on modmyi.com that covered exactly how to hook up a jailbroken iPhone to VoIP using an application called SIAX.

The issue with using your regular home account is that the password is encrypted, so you have to sort that out before setting anything up. Just copy and paste this URL into your browser and change the bolded parts accordingly.

https://im-config.vonagenetworks.net/config?&login=YOUR_VONAGE_USERNAME&password=YOUR_VONAGE_PASSWORD&type=1003

On that page you will find the ProxyUserPassword. Keep that info for later.

On the iPhone, download SIAX through the Cydia installer. Once installed, just press the accounts button and add a new SIP account and add this info.

Domain: a.vonim.com:10000
Username: YOUR_USER_NAME
Password: ENCRYPTED_PASSWORD

Then just turn the account to on and you should be able to make calls using your Vonage account, assuming you are within range of a Wi-Fi network. Given I barely use my 500 Vonage minutes in a month and I’m on pay as you go with my phone this is so awesome as it lets me use the minutes I pay for already anywhere I have Wi-Fi.
