Sangoma Signaling and Media Gateway (SMG): BRI (ISDN) Interface Card Brings Carrier-Grade Thinking to Your Enterprise

This paper is the first in a series of white papers that will introduce and explore several mature, open source VoIP technologies that may not be well known, but are worthy of serious consideration. Over the course of the series, the paper will explore how organizations can take advantage of these emergent, reliable, and scalable technologies. This paper will focus on Sangoma's recently introduced A500 BRI card, and by doing so introduce Sangoma SMG, the Sangoma Signalling and Media Gateway.
