If there was one app I’ve desperately wanted on my T-Mobile BlackBerry Bold, it was a good mobile VoIP client that allows me to make and receive calls over Wi-Fi and 3G connections. It would be even better if that client was made by Skype. Unfortunately, that hasn’t been the case.
In fact, there hasn’t been a native mobile VoIP application for the BlackBerry platform. Instead, we have apps that use either callback or a local access number over the cellular networks. The other three major smartphone platforms — iPhone OS, Android and Symbian — have multiple mobile VoIP applications, including Nimbuzz and Truphone.
Nearly 100 million users are expected to be using mobile VoIP by 2012. With over 471 billion calls likely to be made via mobile VoIP by 2015, it seems BlackBerry has been missing out on the party. That changes today. TringMe, an Indian VoIP startup based in Bangalore, has introduced a new VoIP application for BlackBerry OS (works with Blackberry OS versions 4.2 to 5.0) that can make calls over Wi-Fi. It allows for a single-click, worldwide conference calling, and when there’s no Wi-Fi, it can switch to the local-access number/callback over the cellular network.
If you want to try it, go to http://bb.tringme.com via your BlackBerry browser. After you install the app, “Call Using TringMe” appears as an option when you want to call a contact from the address book or call log. TringMe is offering a white label version of this application to companies that want to extend their internal voice systems to employee BlackBerry devices. You can also use your own SIP provider, except you have to configure your SIP settings, which isn’t an easy task.
