摘要：
This paper presents the architecture and design of an enhanced VoIP gateway, which is based on the H.323 protocol. The key characteristics of this gateway include: scalability separating signaling from media transformation and use of protocols such as MGCP/MEGACO for the communication between signaling part and media gateway; lightweight by using SCTP transport protocol to convey H.323 and MGCP/MEGACO signaling and QoS support through the control of the voice encoding of the VoIP connections. This control Is accomplished by estimating the network load and enforces the voice connections to modify the encoding scheme according to the estimated network load.
