Avaya #1 VoIP PBX Vendor?

I was too busy yesterday to blog this news, but thought it was still important enough to mention. Yesterday, I received an email stating that Avaya, a traditional PBX manufacturer had "widened its lead in worldwide enterprise Internet protocol (IP) telephony revenues." The report showed Avaya as the #1 vendor in IP telephony revenue. This caught my eye for a couple reasons. One, I thought that Cisco, a traditional networking company that became a IP-PBX manufacturer, was the #1 vendor. Second, hearing how Avaya had increased its revenue lead made me wonder how much impact open-source IP-PBX solutions such as Asterisk are truly having on the VoIP market.
\n
\nAfter all, I would have thought by now that Avaya, Nortel, Toshiba, and other traditional PBX manufacturers would have "dips" in their revenue numbers due to inexpensive solutions from Digium, Fonality, Switchvox, and a ton of other low-cost Asterisk-based IP-PBXs, which rival the feature-set of more expensive traditional PBX solutions. As I mentioned in my Top 10 Reasons Why I love Asterisk, I'm a huge fan of Asterisk, which was founded by Digium's Mark Spencer. Although, I'm supposed to be an objective reporter, I can't help but root for open source solutions, including Asterisk.
\n
\nUnfortunately, no Asterisk-based solution is a publicly-traded company, so that makes it difficult to track revenue from Asterisk deployments, which I have no doubt are growing. Now, this isn't to say I don't like Avaya, Nortel, Toshiba, etc. They have some great products that I've tested over the years. It's just fun to root for the underdog - the David over Goliath, ya know?
\n
\nIn any event, here's an excerpt of the release that went out yesterday showing Avaya continuing their dominance in VoIP. Any thoughts on this? Post a comment.
