Huawei eSpace U1911 unified gateway (U1911 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.
U1911 uses the SIP architecture, features high integration, and supports 100 users per subrack. U1911 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.
