A SIP (Session Initiation Protocol) gateway is used to connect different communication systems, such as traditional Public Switched Telephone Network (PSTN) systems and Voice over IP (VoIP) networks, allowing them to communicate with each other. It translates protocols between the two systems, enabling voice calls, video calls, and other media to be transmitted seamlessly. This is particularly useful for businesses transitioning from legacy phone systems to modern IP-based communication solutions.
