Nortel + Microsoft = Unified Communications.

"Microsoft is teaming up with Nortel, to integrate voice, e-mail and video, reports the Seattle Times. Last month Microsoft unveiled a roadmap for new unified communications with software such as Microsoft Office... Nortel's IMS system is likely to be a key piece of the Microsoft deal. It enables a subscriber to launch a video conference during a voice conversation, or access a personalized Video-on-Demand service subscription not just from their home TV, but online from a laptop, a hotel room or from a mobile phone, for example... Microsoft and Nortel will be competing with the likes of IBM and Cisco in the unified communications arena. Nokia and Siemens entered a carrier infrastructure joint venture last month."
