Nokia :: E72 - Setting Up VOIP Via SIP

It's taken the better part of a day to figure out, but I finally have SIP working on the Nokia E72. I have worked my fingers to the **bleep** bone, but after five or six hours of searching and banging my head against a wall, it finally works. I've decided to document this struggle so that others may perhaps endure less suffering.

In case it makes any difference, I'm using the North American version of the E72. The model is listed as being an E72-2, RM-529. It was purchased through Expansys: it's unlocked and carrier-neutral, straight from Nokia.

Naturally the first thing I did was set up a generic SIP profile. Try as I might, no matter what settings I used, it simply would not work. First there was no option for an "internet call" in my contact list (see below for the problem). Then, when I figured out how to get it to show up, it would always return "Authentication failed" when I tried making a call.

I won't discuss my unsuccessful attempts any further: I will instead describe for you, step my step, the magic dance I did to make it all work.

Setting up SIP on the E72

1. Go to your Control Panel and into Net Settings.

2. All you see at first is an option called "Download." This retrieves a list of "services" that Nokia makes available to you.

3. Click on the Gizmo5 service. This is a sip / voip provider that would probably work very nicely with your phone, but Google bought them out a few months ago and now they aren't taking any registrations. Your phone will now download and install a Gizmo5 app...

4. Next you'll be asked if you'd like to create an account. Click No until it stops nagging you.

OK, what we've done now is install the Gizmo5 service on the phone... if you go back to Control Panel > Net Settings you'll see this:

Now if you open up your contact list, you'll see an option for Internet Call:

5. That's great, but you're not done yet. Now go to your SIP settings through Control Panel > Settings > Connection > SIP Settings. My phone looked like this:

Note that I have two profiles... the second one is my first and unsuccessful attempt at getting everything to work; just ignore it. What you'll see is the GIZMO VoIP profile. The secret sauce is that you have to edit this profile... just overwrite everything with your SIP provider's information, though I'd leave the profile name alone.

6. That's it. Enjoy your SIP calls.
