	How can I get Gizmo5 on my Pocket PC or Windows Mobile device?

Solution Sorry, but there is NOT a version of Gizmo5 for the Pocket PC. However, it is possible to make Gizmo5 calls on your Pocket PC, by using standards based software, like SJPhone.

You can download Gizmo5 mobile for your Windows Mobile device at: http://gizmo5.com/pc/download/

Download and install your SJPhone client for Pocket PC from here.
Click 'menu' and select Options.
Click the 'Profiles' tab and then select 'New'. Name the profile "Gizmo5" and select "calls through SIP proxy" for 'profile type'. Click 'Ok'
On the first tab of the 'Edit' window for the new gizmo profile. Use the default settings, but also check the 'Inquired' and 'Saved' boxes for 'full address of'.
On the Sip Proxy tab enter the 'proxy domain' as 'proxy01.sipphone.com' with port '5060'. Leave the 'user domain' field empty. Check the following boxes: 'Register with proxy', 'Proxy is strict outbound' and 'Unregister contact address only'.
No changes need to be made to the 'General' and 'DTMF' tabs.
On the STUN tab check the box 'Use discovered addresses in SIP' and enter 'stun01.sipphone.com' as the server address. Set the port to '3478'.
Click 'ok' to apply these settings to the profile you created.
After selecting the profile you just created, click initialize.
Enter your SIP Number (11 digits, no dashes) for "Account", your Gizmo5 password, and for 'Full address' enter your SIP URI.
Click 'ok' to return to the profiles tab. Then click 'ok' again to return to the SJPhone main screen.
From the 'Menu' select Services->Re-initialize selected service. Then click 'ok' on the screen that appears. You should now be able to make and receive calls with your pocket pc.
[optional] You might have to free up ports 5060 (UDP) and 5004 (RTP) on your firewall and/or router if for some weird reason you can't connect to the service.

Please note that SJPhone is pretty slow on PocketPCs. After you do a call, and you click on hang up, it will take a while to apply the hang-up. At that time, your PocketPC will appear frozen. It has not crashed, just frozen temporarily, because the SJPhone client is not really optimized for small devices (it is a straight port of the desktop version). Just wait for a bit and your pocket pc will come back to life soon enough.
