Is Enterprise-Level, Open Standard, Open Source VOIP A Myth?
By Deke Kassabian

Published August 2007; Posted April 2008



The purpose of this article is to briefly describe the aspects of open, SIP (Session Initiation Protocol)-based telephony that most completely mirror the conventional vendors’ IP-PBX offerings, and those that the open source community is still working to develop. We also will explore the reasons why open source SIP-based telephony suits some organizations better than others today, and touch on a future in which phones, laptops, handhelds and other SIP user agents can take part in a range of unified communications and unified addressing, all in the context of rich presence.
