In a few short weeks Microsoft will officially release Office Communications Server 2007 (OCS 2007) R2. R2 represents a big step forward in the evolution of Microsoft’s voice and unified communications platform and a significant evolution toward software-powered voice (eliminating the PBX or IP PBX altogether).
One of the most anticipated improvements with OCS 2007 R2 is direct SIP- the ability to connect a SIP connection directly with OCS 2007 without the need for an audio gateway to mediate the communications. In this blog post Evangelyze Communications Director of Services, Mike Stacy, describes his experience configuring a direct SIP connection between OCS 2007 R2 and VoIP provider Global Crossing. Mike also explains some of the lessons he learned from the experience.
