eSpace EGW1500E Enterprise Gateway
Product Description	4 Functions and Features

4.1.3 Voice QoS

This topic describes voice QoS policies supported by the EGW1500E.

VAD

Voice activity detection (VAD) is a technology used in speech coding and speech recognition where the presence or absence of human speech is detected. The VAD avoids unnecessary coding and transmission of silence packets in Voice over Internet Protocol (VoIP) applications, saving computation and network bandwidth.

CNG

Comfort noise generator (CNG) is used with VAD. When the VAD function is enabled and no packets are sent during the silent period, the listener may think that the call has disconnected. To avoid this, the EGW1500E enables the CNG function on the receiver end. The EGW1500E CNG technology complies with RFC3389.

EC

Echo cancellation (EC) is a process of removing echo from a voice communication to improve voice quality on a telephone call. In addition to improving subjective quality, this process increases the capacity achieved through silence suppression by preventing echo from traveling across a network. The EGW1500E EC technology complies with ITU-T G.168.

PLC

Packets are often lost on the connectionless IP network as a result of network congestion, buffer overflow, or bit error. A packet loss compensation (PLC) algorithm is used to minimize the effects of packet loss. Lost frames can be reconstructed during decoding based on the voice context, which ensures the quality of the received voice.

Jitter Buffer

When the jitter buffer function is enabled, received packets can be buffered and then retrieved and processed to remove jitter.

4.1.4 Reliability

The EGW1500E provides various technologies to ensure voice communication reliability.

Multi-SIP Registration–DR Mechanism in a Small Branch

Multi-SIP registration is a disaster recovery (DR) mechanism that ensures service continuity in emergencies such as SIP server breakdown. Functioning as a voice access device in small branches, the EGW1500E can register with two SIP servers at the same time. When the active SIP server is faulty, the EGW1500E switches services to the standby SIP server. When the active SIP server is restored, the EGW1500E switches services back to the active SIP server.
