Agito Networks is trying to let businesses get more out of their BlackBerry smartphones, and it's bringing VoIP over Wi-Fi and unified communications to Research In Motion's handsets.

The company's RoamAnywhere Mobility Router already brings VoIP over Wi-Fi to other smartphones, including Symbian and Windows Mobile devices. By adding support for BlackBerry smartphones, the company has a better chance of appealing to U.S. businesses because RIM is dominant in the enterprise mobility space.

Agito said the VoIP feature could be a "game changer," as it will enable globe-trotting mobile professionals to save on international calling expenses, as well as help with in-door reception. The company said the VoIP is achieved using approved application programming interfaces, so companies don't need to worry about unlocking, or "jailbreaking," devices.

Agito's Mobility Router also extends an enterprise's voice infrastructure and unified communications to the BlackBerry smartphones. For example, users can receive calls to their office numbers on the handset, as well as do extension dialing from the BlackBerry.

"The industry has been asking mobile UC vendors to deliver support for BlackBerry smartphones for years, including vendors who have been in business and trying longer than Agito Networks," said Pejman Roshan, Agito's chief marketing officer, in a statement. "Agito has continued to distance itself from the competition due to its innovate and differentiated functionality, which has been widely recognized."

The company will support BlackBerry models such as the Bold, the Curve 8900, the Curve 880, and the Curve 8300 for GSM providers. Agito said it's working on support for devices on CDMA networks, like the BlackBerry Storm. BlackBerry support will be available early next month, and per-user costs vary by the size of the deployment.
