A VoIP gateway is a hardware device that converts Time Division Multiplexing (TDM) telephony traffics from the PSTN into digital IP packets for transport over an IP network / the internet and vice versa.
A VoIP gateway is a bridge between two systems, legacy telephone infrastructure like analog telephones, fax machines, legacy PBXs, and modern VoIP networks with SIP (Session Initiation Protocol). The key features of a VoIP gateway are encode/decode, SIP, routing.
