Networking giant made its initial offer for the video-conferencing company in October but got the thumb's down. Six months later, Cisco seals the deal.
Just shy of 90 percent of Tandberg shares as it passes a self-imposed drop-dead deadline, Cisco says its acquisition plan is still very much alive.
After its initial bid got the cold shoulder, Cisco has upped its buyout offer for the video conferencing equipment maker.
As part of its expansion into videoconferencing and collaboration, Cisco Systems antes up for the Norwegian video communications company.
Joint venture announced Monday is designed to compete with Cisco after its recent acquisition of Tandberg and bring companies inexpensive video-conferencing services.
Tandberg will try a version for the business market.
