The Grandstream GXW4502 E1/T1/J1 Digital VoIP Gateway is an enterprise-grade digital gateway designed to connect traditional PSTN, ISDN, and legacy PBX systems with SIP-based VoIP networks. Featuring two software-configurable E1/T1/J1 spans, the GXW4502 enables organisations to integrate existing digital telephony infrastructure with modern IP communications while reducing migration costs and protecting previous investments. It is ideal for medium and large businesses, service providers, call centres, and multi-site deployments.
The GXW4502 supports up to 60 concurrent calls and provides broad compatibility with SIP platforms and digital signalling protocols including PRI, SS7 and MFC R2. The gateway includes dual Gigabit network interfaces, advanced voice processing technologies, enhanced security features, and flexible provisioning options for reliable large-scale deployments.
The GXW4502 allows organisations to maintain existing digital telephony infrastructure while transitioning to IP-based communications. This reduces infrastructure replacement costs and simplifies migration to modern SIP systems.
