First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.
Open source PBXs make corporate gains; how much is a debate

Infonetics did find that the worldwide growth of PBX sales did grow 1 percent last year, but that growth figure was also a drop from the 7 percent growth it reported the year before. "I would say it was the economy," he says, not the incursion of open source alternatives that accounts for the decline.
Machowinski said open source PBX vendors should be willing to claim such numbers. "If this is really the case, why won't companies like Digium report what their line shipments are?" he says. "You'd think that would be something they'd like to provide."
Bill Miller, vice president of product management for Digium, which sells commercial Asterisk products and peripherals, says all the company knows for sure about the software s the number of downloads, but not whether they are actually used.
But he has estimates based on downloads and the purchase of peripherals such as line cards and codecs for the systems that give an indication of what I actually in use. He puts that number at 2.7 million lines installed in North America last year, which is more than Eastern Management's estimate. He estimates that just 5 percent of the downloaded Asterisk PBX software is in production use at businesses.
Machowinski says that someone could install a free open source IP PBX but that doesn't necessarily mean they would have bought one from a proprietary vendor if there were no open source alternatives. So the 18 percent that use open source might not represent a loss to the leading non-open-source PBX vendors. "Even if it's 18 percent, does it displace 18 percent of the market?" he says.
Malone acknowledges the difficulty of accurately measuring open source PBX use. The software can be downloaded anonymously with no way to know if it is ever put into a live business network, he says.
The open source study is the most massive one his firm has undertaken in 30 years. It relied on using raw download numbers plugged into an analysis model built based on responses the firm got from those surveyed as one predictor of the market.
Malone says that within three weeks he will have complete 2008 PBX sales data provided by manufacturers to plug into his calculations that will result in refined 2009 projections.
