The communications world is split in two—between the things you do on the telephone and the things you do on the computer.

The split exists because most real-time (synchronous) communications—like telephone calls and voice mail—depend on one network, while message-based (asynchronous) communications—like e-mail—depend on a separate, incompatible network.

The split creates problems—lots of them. Phones aren't as intuitive as they should be. Just try to start a three-way call without hanging up on someone. On a computer, you can check your e-mail, but not your voice mail. And then there's the enormous cost of purchasing, maintaining, and upgrading two complex infrastructures.

To get your phones and your computers talking, you'd have to tear out your entire telephone system, dump your PBX, replace every desk phone, swap out every phone jack. In short, you'd have to start from scratch.

Microsoft unified communications technologies bridge the divide between computers and telephones with two integrated servers: Microsoft Exchange Server 2007 and Microsoft Office Communications Server 2007. They integrate with your company's existing phone system and deliver complete communications services using your existing data network.

No forklift required: Microsoft unified communications technologies maximize your existing infrastructure by integrating legacy PBX systems through a VoIP/IP-PBX gateway.

With Microsoft unified communications technologies, the computers on your network gain the functionality of advanced VoIP phones. Users can click to call any contact in their address book. A simple phone call can become a conference call or a video conference, on the fly.

Microsoft unified communications technologies tear down the walls that separate telecommunications and computing—and they do it with software that takes advantage of your existing telecommunications infrastructure.

Microsoft unified communications technologies are more than just VoIP. They break down all the traditional communications silos. Voice mail and faxes move over the network like e-mail. They arrive in your Microsoft Office Outlook inbox where you can sort, prioritize, and forward them, just like any piece of e-mail.

And when you're on the road, you can dial in over any telephone to hear your e-mail messages and your calendar. You can even access your Outlook address book and call anyone in it just by speaking his or her name.
