Verizon Wireless made two announcements Monday, while AT&T made a separate announcement of a service , that allows enterprise apps to run on any phone a user chooses. Separately, Verizon announced the Private Applications Store for Business that allows companies to run in-house or third-party apps on any or tablet on any network. It will be offered later this year, with pricing set on a per-user/per-month basis, although Verizon didn't specify how much.

Also, Verizon introduced its Mobile Unified Communications Client to connect Android smartphones over the Verizon network with a business' existing telephone system. That means Android smartphone users can place calls on the device from their work number, even while out of the office, with the calls routed through the company's IP PBX system. The advantage is lower costs on international calls and intra-company calls.

Verizon created a docking station, sold separately, to connect phones running the Android mobile operating system and using the UC Client to a company's Ethernet. The UC client is now available for $7 a month per user, while the docking station costs $125.

The UC Client supports the Droid X, Droid X2, Droid 2, Droid 2 Global and Droid Pro, all Android phones from Motorola. Others devices will follow.

The UC Client works with IP PBX software from leading makers, including Unified Communications 6.1.4 and above and Avaya Communications Manager 5.2 and above.
