The limitation comes from incorporating the Skype service, Miller said. Even if two users both had Passport systems, and they called each other via Skype -- an unlikely scenario -- the maximum quality would be only 640 by 480, she said.
However, many users will accept this loss of quality in order to bring more participants into a call, said Wainhouse's Davis. Consumers already cope with poor mobile call quality for convenience, he said.
"What the last few years have shown ... is that people want the best quality, but they are very happy to live with less when other things come into play," Davis said.
The software upgrade will come with version 4.8 of the Passport software, available for downloading free this month, and will come pre-installed in future systems. The Passport platform is designed for small and medium-sized companies. It includes a high-definition camera, a microphone and a codec device, for about $2,500. The Passport is designed for use ideally with an HD display of 42 inches to 50 inches, which the customer supplies.
