In addition to broadband services, such as video on demand (VOD) and live data and video, the AR provides high-quality voice service for terminal users.
SIP AG
Access gateway (AG) devices provide various access modes and convert various services into a uniform format that can be transmitted. The AG communicates with the soft switch by using the SIP protocol. SIP-based AGs are called SIP AGs.
When an AR functions as the SIP AG, the upper-layer devices such as soft switch control and manage calls. The Huawei AR Series Routers supports the following services.
