Polycom SIP 2.2.2 manual IP Type-of-Service-Allows for the setting of TOS settings

Administrator’s Guide SoundPoint IP / SoundStation IP

—IP Type-of-Service—Allows for the setting of TOS settings.

—Jitter Buffer and Packet Error Concealment—Employs a high-performance jitter buffer and packet error concealment system designed to mitigate packet inter-arrival jitter and out-of-order or lost (lost or excessively delayed by the network) packets.

—Low-Delay Audio Packet Transmission—Designed to minimize latency for audio packet transmission.

—Voice Activity Detection—Conserves network bandwidth by detecting periods of relative “silence” in the transmit data path and replacing that silence efficiently with special packets that indicate silence is occurring.

•Security Features

—Local User and Administrator Privilege Levels—Several local settings menus are protected with two privilege levels, user and administrator, each with its own password.

—Configuration File Encryption—Confidential information stored in configuration files must be protected (encrypted). The phone can recognize encrypted files, which it downloads from the boot server and it can encrypt files before uploading them to the boot server.

—Custom Certificates—When trying to establish a connection to a boot server for application provisioning, the phone trusts certificates issued by widely recognized certificate authorities (CAs).

—Incoming Signaling Validation—Levels of security are provided for validating incoming network signaling.
