Due to a reporting error, the story, "Vidyo virtualizes its video-call infrastructure" incorrectly characterized the pricing of Vidyo's products.

The story has been corrected on the wire. The seventh and eighth paragraphs now read as follows:

The cloud-based technology will save money even though a Virtualized Vidyo Router will cost more than a physical unit, according to Vidyo. In an example case, a Vidyo Router costs about US$13,000, including licenses to run meetings with as many as seven concurrent participants. But with the dedicated hardware, additional Vidyo Router boxes, at $6,000 each, are needed in each region of the world to take advantage of local network connections.

By contrast, the Virtualized Vidyo Router will cost about $17,000 with the same number of licenses, but it can be redeployed on public or private cloud capacity in each region as the bulk of user activity moves around the world with the business day. That cloud capacity can be from Amazon Web Services, another public cloud, or standard server capacity in a private data center.
