首頁 > The Open-Source Opportunity Expands
Will this be the year open-source PBX and VoIP systems are ready for their close-up? The opportunity is better than ever, argued attendees at January's Digium Asterisk World conference in Miami. According to one researcher, Eastern Management Group, open-source PBXes now account for 18 percent of all PBX sales in North America -- and that number's rising.
Asterisk is the heavyweight of open-source PBX platforms, commanding some 88 percent of North American market share. Most of the following open source PBX vendors were on hand at Digium Asterisk World and specialize in Asterisk solutions, but Asterisk is also one PBX platform of several, with plenty of alternatives nibbling at its heels. Here's a roundup of 15 of the most notable open source PBX vendors out there. Many are focused squarely on SMB, though that could change as open source continues to gain greater enterprise acceptance, and most have channel programs.

CoreDial VoiceAxis 3.0
CoreDial's VoiceAxis is a turnkey software package targeted to enterprise-level businesses and service providers. The suite is designed for the management, billing and provisioning of hosted PBX, VoIP, SIP trunking and other related products -- essentially a one-stop management tool that Asterisk lovers have embraced for its ease-of-use with Asterisk PBXes. Version 3.0 of VoiceAxis arrived in October 2009.
Dialogic DiaStar Server
Dialogic's DiaStar Server is a platform for app dev -- Asterisk-based or otherwise -- around functions like call progress analysis, fax, fax over IP, SS7 and Sigtran. The goal, according to Dialogic, is to get developers as much flexibility as possible, whether they want to leverage PSTN protocols like ISDN, SS7 or CAS or provide rich applications around voice and video. For LAN environments, Dialogic uses Woomera, the open-source IP-based signaling protocol.
