10 Hot Networking Companies With IPO Potential


Digium

Founded: 1999

The open source PBX Asterisk -- and the company's VoIP-in-a-box turnkey Switchvox -- have propelled Digium to rich successes and steady growth in the channel. Thanks to high profile partnerships with the likes of IBM, Polycom and Skype, Digium's profile is also increasing -- and at a good time, too, considering that more than 18 percent of PBXes in North America are open source, according to The Eastern Management Group. Digium supporters have been waiting anxiously on hints of an IPO for a few years now, but the company hasn't yet taken the plunge. How about it, Digium?
