Polycom SOUNDPOINT SIP 2.2.0 - Manual (Page 28)

Administrator’s Guide SoundPoint IP / SoundStation IP
2 - 12
— 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.

parameters, see the appropriate section in Configuring Your System on page
