T-Mobile USA is introducing T-Mobile Wi-Fi Calling for Business, a new enterprise solution that allows business customers and their employees to make unlimited nationwide calls over Wi-Fi for 10 bucks per month.
The UMA-based dual-mode offer works at any T-Mobile HotSpot or any “open” Wi-Fi hotspot. Calls will seamlessly transfer onto T-Mobile’s cellular network when outside the hotspot range.
Businesses with more than 100 lines of voice and data service can add BlackBerry smartphones from T-Mobile to receive free Wi-Fi calling nationwide and from abroad to the United States.
T-Mobile also said it will be adding the BlackBerry Mobile Voice System to in the coming months, becoming the second carrier after Sprint-Nextel Corp. to do so. The BlackBerry MVS integrates the functions of a desk phone with a BlackBerry smartphone. Mobile workers can streamline their communications with one corporate phone number that simultaneously rings up to four devices, one caller ID and a consolidated voice mailbox. BlackBerry users also can access enterprise desk phone functions like transfer, allow and block callers, and seamlessly hand off calls between BlackBerry smartphones and desk phones using the integrated interface on the BlackBerry.
With the business Wi-Fi calling offer, T-Mobile is leveraging its expertise as the provider of the Hotspot@Home nationwide residential VoWiFi service.
