A SIP-I Gateway is an essential tool in modern telecommunications. It bridges traditional SS7-based ISDN User Part (ISUP) networks and newer, IP/VOIP-based systems that use the Session Initiation Protocol (SIP).
SIP-I (Session Initiation Protocol with encapsulated ISUP) allows ISUP signaling messages to be embedded within SIP messages. This leads to cohesive and reliable communication.
For telecom operators managing hybrid environments, a SIP to SS7 Gateway streamline operations, reduce costs, and improve service delivery—while still supporting high-quality voice and video communication.
Telecom operators are under growing pressure to meet demands for interoperability, scalability, and cost efficiency. A SIP-I Gateway helps address these challenges by providing seamless SS7 and SIP interworking capabilities, including:
The Deltapath SIP-I Gateway is a powerful solution designed to seamlessly support legacy SS7-based ISUP networks with modern SIP-based IP/VOIP networks. As telecom operators face growing demands for interoperability, scalability, and cost efficiency, this gateway offers a smooth path to modernization—without disrupting existing systems.
Engineered specifically for telecom environments, the Deltapath SIP-I Gateway encapsulates ISUP signaling within SIP messages, enabling effortless communication between traditional and next-generation networks. Whether you’re operating in a hybrid setup or moving toward a fully IP-based infrastructure, you can count on reliable, high-quality connectivity across all systems.
