In the closing days of 2007, open source voice-over-IP (VoIP) project WengoPhone found itself without a sponsor. The project's creator and underwriter, Wengo, announced it was halting its support after more than three years of development. Fortunately, longtime contributor MBDSYS offered to take over maintainership of the project, and has begun the transition, setting out a roadmap and reinvigorating the developer base.

Wengo -- the commercial PSTN-routing SIP provider that is the open source project's parent company -- focused on its Windows builds and essentially skipped over Linux during the 2.0 release cycle. OpenWengo's Linux developers were never satisfied with the stability of the 2.0-series release candidates, so they never incremented the Linux version number to 2.0.
