RIM said BlackBerry Mobile Voice System (MVS) 5.1 now supports OpenScape Voice V6 from Siemens Enterprise Communications.

BlackBerry MVS is combined with OpenScape Voice to provide a Fixed-Mobile Convergence (FMC) application for BlackBerry smartphone users.

Integrating BlackBerry MVS and OpenScape Voice will enable Siemens Enterprise Communications customers to place and receive desk phone calls on their BlackBerry smartphones and enjoy the convenience of single number reach, extension dialing and phone features such as hold, transfer and ad-hoc conferencing.

For connection with OpenScape Voice, customers can use AudioCodes Mediant Gateway, which will allow BlackBerry MVS to be used with mobile as well as Wi-Fi networks.

The BlackBerry MVS will route the calls through the company’s phone system and will also allow administrators to set IT policies, control to take advantage of least-cost routing and save on long-distance and international roaming charges.

Call routing through the corporate phone system can also help with adherence to company policies and regulatory compliance requirements.
