Standard, Open Source VOIP A Myth?

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.
