A VoIP Gateway allows you to convert between a legacy telephony connection, such as E1/T1/PRI and a modern VoIP connection using SIP. This is known as "digital gateway" because the voice media is converted between a digital TDM connection and a VoIP connection. The conversion can go from SIP to TDM, TDM to SIP or even SIP to SIP for the purposes of failover or transcoding.
Not only was Digium the first vendor of telephony interface cards built specifically for Asterisk, but it has always been the market leader, with over 50% of the world’s board business.
