I think the think that cell phone companies will come out with a product that will integrate cell phones on to their network for a flat fee per handset. If I charged a company $99 a month to make the handset a virtual SIP or IAX extension where company transfer, extensions, and the like worked I still have a huge market. Gone may be the power user who goes through $400 minutes a month, but (s)he is probably on an unlimited plan already. Whether the companies can gouge you more for Blackberry on top of this remains to be seen.

Research In Motion is to release a version of its Mobile Voice System Server product for Cisco's Unified Communications Manager, the Canadian handset manufacturer announced on Monday.

Mobile Voice System (MVS), which RIM originally brought out in 2007, turns the BlackBerry smartphone into an extension of the corporate PBX. Its customisation for Cisco's unified communications (UC) system marks the first time it has been tailored to any one particular vendor's PBX.

One feature of the new product is the ability to have up to four devices ring at once, including BlackBerry smartphones and Cisco Unified IP phones. It will also be possible to dial out from a RIM smartphone using either the BlackBerry number or the enterprise line, and to move a call from the handset to a Cisco Unified IP phone without breaking the session.

As a unified-communications system, it provides one contactable corporate phone number, one caller ID and one voice mailbox, working across both the handset and the deskbound IP phone.
