How to Make VoIP Calls on a Pocket PC Using Express Talk.

From WikiHow. The do it yourself manual.

Want to utilize the cheap rates of VoIP (Voice Over IP) from your mobile device ?.

If you have a Pocket PC or a device that uses Windows Mobile with an Internet/Network connection you can now make calls via VoIP with Express Talk's "Pocket Talk" application.

Steps

  1. Download Express Talk for Pocket PC.
  2. Once you have downloaded the setup.exe to your PC or Mac you will need to install it on your mobile device.
  3. When the application has been installed on the mobile device you are ready to make calls.
  4. You can make free VoIP calls if you are connecting to someone else with a softphone installed on their PC or Mac (see below in the "tips" section).
  5. To make calls to a regular phone you will need a SIP Service Provider (see below in the "tips" section).
  6. Enter the number you want to call using the keypad on the application or you mobile device keypad and then click the green telephone button.
  7. If you know that a friend has Express Talk installed on their mobile device, Mac or PC you can even "page" them with the Intercom button, like a CB radio.

Tips

  • With Express Talk you could potentially call someone using their internet IP (eg. "bob@123.222.333.444") but this is not usually practical. It is much easier to use a friendly address like "bob@myphoneco.com". To have this you need to sign up with a SIP proxy service. This is almost always free to signup for and usually requires nothing more than an email address.
  • Some of the companies also provide gateway services. This means cheap phone calls to ordinary (non internet) lines. They are particularly cheap for international calls since you only pay the local call rates.


Warnings

  • Pocket Talk allows you to trial the application for 14 days before a license is required. Apparently a freeware version will be made available soon.

Things You'll Need

  • Pocket PC or Mobile device running Windows Mobile OS
  • ARM CPU (this covers almost all models)
  • Internet or network connectivity from the device
  • SIP service Provider.
