One of the key devices with traditional telephony is a wireless handset, both in residential as in business use. When it comes to VoIP telephony, cordless telephones are nowhere near as standardized as their analog counterparts. One of the reasons for this, is the standard used for wireless VoIP telephony, or the lack thereof. While it would obviously make sense to opt for WiFi as the cordless VoIP standard, the technology has its issues when it comes to real-time communication.

While it is already possible on some handsets, VoIP over 3G networks doesn’t make sense economically in most countries. Even where flat rate data plans are available, they usually contain some kind of fair use policy, which will allow the operator to disconnect you from the service at any time. Yet VoIP on mobile handsets is ever increasing in popularity both in the consumer as in the business marketspace.

I’ve been waiting impatiently to write something about Apple’s iPhone on this blog, but alas Apple chose not to include VoIP functionality on the device (among many other things; the phone is seriously lacking in the feature department) so the iPhone remained irrelevant to this blog.

To a certain extent it still does. Yes, the device is beautiful and it probably has the first ever operating sytem done right on a mobile phone. Don’t get me started about Symbian, Windows Mobile or Linux for that matter. But I digress.

It seems Blackberry users are finally getting VoIP support as well. While Nokia has been offering excellent VoIP support on its E-series platform, users of other smartphones (including Blackberry, Palm and Windows Mobile based devices) have been left in the cold. This is a great move by RIM because business users aren’t generally interested in cheaper minutes, but will be interested in connecting their smartphone to the company’s phone system.
