Enterprise Cellular Telephony Enhancements

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

Enterprise cellular telephony, also known as outside voice, enables users of the 2007 R2 version of Microsoft Office Communicator Mobile for Windows Mobile and users of the new Microsoft Office Communicator Mobile for Java to set up and control Enterprise Voice calls over their cell phone providers’ circuit-switched networks. With enterprise cellular telephony, a user’s cell phone becomes just one more unified communications endpoint, providing nearly the same level of connectivity and control as Office Communicator itself. These features include the following:

• Click to Call

  A cell phone user can place a voice call by clicking on a contact’s single phone number or SIP URI.

• One-Number Calling

  Each user has a unique single number through which all the user’s registered endpoints, including his or her cell phone, can be reached. The user will be contacted on whatever device is available. People who want to call the user need to keep only that single number. The user, in turn, only has to hand out that one number and does not have to share his or her cell phone number.

• Least-Cost Routing

  A call placed from a supported mobile client to a long-distance PSTN number can be routed over the enterprise IP network to the PSTN gateway that is nearest to the location of the destination number. Routing mobile workers’ calls in this way over the enterprise IP network usually results in lower costs than if the same calls were routed entirely over the PSTN.
