At the VoiceCon show now underway in Orlando, Florida, Research In Motion is giving the VoIP capabilities of its BlackBerry 7270 a heavy marketing push.

This device connects through the BlackBerry Enterprise Server to make and receive wireless VoIP calls through enterprise telecom systems compatible with Wireless Local Area Networks.

“Extending desktop productivity to mobile professionals is one of the central value propositions that made BlackBerry successful in the enterprise and similar productivity benefits can be provided to on-campus workers who spend significant time away from a desk," RIM co-CEO Mike Lazaridis said in a statement this morning. "The BlackBerry WLAN solution lets organizations drive productivity benefits to a growing number of on-campus mobile workers by leveraging their existing investments in WLAN and IP-PBX infrastructure."

Lazaridis added that key industry sectors that could benefit from this solution include "healthcare, manufacturing, hospitality, education, retail and distribution where campus-wide access to voice and data is beneficial."
