Microsoft To Take On Cisco In Unified Communications

Microsoft’s move into what it calls “unified communications” will spark a turf war with powerful players, including PBX makers and Cisco, that will all attack the market from their relative positions of strength, partners said.

In the process, Microsoft and these players—most of which are also its partners—will square off for a bigger chunk of an estimated $40 billion worldwide market for voice/telephony software and infrastructure, partners say.

Microsoft will start to talk more about its plans at a unified communications event in June, said Zig Serafin, general manager of Microsoft’s Unified Communications Group (UCG). Sources said to expect more information on the next Live Communications Server (LCS).

The upcoming LCS will offer on-premise presence and instant messaging (IM), as well as audio-, video- and Web conferencing, sources said. The current LCS does IM and on-premise presence, while Web conferencing is the province of Live Meeting, a hosted service underlying Microsoft’s current Live Meeting, which grew out of Microsoft’s acquisition three years ago of Placeware.

Unlike Exchange Server 2007, the new LCS—once known by its code name, Kiev, and now referred to internally simply as Live Server—will not be 64-bit only. It will be part of the Office 2007 “wave,” Serafin said.

The public message will be one of collaboration between Microsoft and partners such as Cisco, Avaya and other makers of PBXes. Behind the scenes, though, all of those companies will compete for many of the same customer dollars.

“Do the math. The market for collaboration software is $4 billion. The market for voice is $40 billion. If you were Microsoft, where would you go?” asked a Microsoft source who requested anonymity.

The issue is that what Microsoft offers and what Cisco offers in terms of instant messaging are very similar, and few customers will buy both.

“Cisco started with voice, then added conferencing and video and voice mail. Microsoft started with Office and app integration, added presence and IM and conferencing first as a service [and] then on-premises,” the source said.
