If you are a fan of Web-activated calling, and really prefer using your mobile, and want to use a service that actually is easier to use than Jajah (and Jajah is really easy), try Mobivox. Once you upload your directory numbers to Mobivox, you dial a local access number and then use voice prompts to pull up numbers in your directory and then Mobivox connects you.
If you are calling a number not in the directory, you get a prompt to enter the number on the keypad. The voice recognition seems to be quite good. There are no client downloads, even when using a mobile. You can use any phone at all. No need for a smart or feature phone. It is pleasant, easy to use, and the voice activation feature is almost fun (what about "dialing" or "clicking" phone numbers actually can said to be "fun"?).
The ability to use it without a download is really nice, as downloads are a huge barrier to adoption for most people, including me.
