Huawei eSpace U1981 unified gateway (U1981 for short) is a core voice gateway in the Huawei Unified Communications (UC) solution. It works with Huawei IP terminals and UC applications to provide professional IP telephony (IPT) and UC services. U1981 uses the SIP architecture, features high integration, and supports 1,000 users per subrack. U1981 also provides powerful networking capabilities. In the downstream direction, it supports both narrowband and broadband access, allowing for hybrid networking of analog phones and IP phones. In the upstream direction, it can connect to the public switched telephone network (PSTN) or to voice switches in private networks using digital, analog, and broadband SIP trunks. U1981 can be quickly deployed and easily maintained with the assistance of deployment and maintenance tools, thanks to its simple design.
