Surveying the world of VoIP
Published by Steve Litchfield at
Kudos to well respected S60 tipster Antony Pranata for going the extra mile and trying out all the various Voice over IP solutions for smartphones, comparing EQO, Fring, Gizmo, iSkoot and Truphone, with Fring and Truphone seeming to come out winners, depending on your requirements. Also of note is that Truphone's new v3.0 is now available in a full beta.
From the review: "As I said earlier, none of the current VoIP applications satisfy met yet. Some of them have issues with usability, especially user interface. Some others are not reliable. Sometimes, they just drive me crazy because it is so difficult to initiate a call. All of them suffer from sound quality.
