— DTMF Tone Generation—Generates dual tone multi-frequency
(DTMF) tones in response to user dialing on the dial pad.
— Dynamic Noise
sensitivity, while automatically reducing background noise on
SoundStation IP 7000 conference phones.
— IEEE 802.1p/Q—The phone will tag all Ethernet packets it transmits
with an 802.1Q VLAN header.
— IP Type-of-Service—Allows for the setting of TOS settings.
— Jitter Buffer and Packet Error
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
latency for audio packet transmission.
— Treble/Bass Controls—Equalizes the tone of the high and low
frequency sound from the speakers on SoundStation IP 7000
conference phones.
— Voice Activity
detecting periods of relative "silence" in the transmit data path and
replacing that silence efficiently with special packets that indicate
silence is occurring.
— Voice Quality
including MOS and R-factor for listening and conversational quality.
This feature is part of the Productivity Suite.
• Security Features
— Local User and Administrator Privilege
menus are protected with two privilege levels, user and
administrator, each with its own password.
— Configuration File
configuration files must be protected (encrypted). The phone can
recognize encrypted files, which it downloads from the provisioning
server and it can encrypt files before uploading them to the
provisioning server.
— Custom Certificates—When trying to establish a connection to a
provisioning server for application provisioning, the phone trusts
certificates issued by widely recognized certificate authorities (CAs).
— Incoming Signaling
validating incoming network signaling.
— Secure Real-Time Transport
avoid interception and eavesdropping.
