HWD-E3000 is a new-generation intelligent voice gateway designed to meet the business requirements of enterprises, industries, and telecom operators. Featuring carrier-grade reliability, high-density ports, and large-capacity processing, it integrates enhanced functions such as IP voice, IP fax, Modem, and speech recognition over SDH synchronous optical interfaces (STM-1), enabling users to build flexible, efficient, and future-proof communication networks.
HWD-MTG3000 Trunk Gateway supports multiple signaling protocols, enabling seamless conversion between traditional signaling (SS7, PRI) and SIP. Equipped with comprehensive codec capabilities and advanced technologies such as signaling encryption and intelligent speech recognition, it ensures high-quality voice transmission while optimizing trunk resource utilization. This makes it an ideal solution for access networks of all scales, particularly for telecom operators and large enterprises.
