"It probably will. We're not sure how yet," Malloy said. "We're not sure exactly what Microsoft is going to do with Skype. Our sense is that they're going to leave them as a consumer play, because they already have significant traction with Microsoft Lync in the enterprise."

Either way, the big-name acquisition is likely to mark a leap forward in awareness and demand for video, he added. "However it plays out, we think it's going to be good for us."

Longer term, cloud-based services will deliver video for many more enterprises and SMBs, and LifeSize is well-positioned to take advantage of this trend, Malloy said. Cloud-based video takes advantage of centralized infrastructure so customers only need fairly thin, inexpensive client devices to take part and don't have to worry about complex installation issues such as firewall traversal, he said. This should make setting up a videoconferencing system much like installing a tabletop speakerphone, which can be plugged into a standard phone jack and automatically deliver dial tone, Malloy said.
