CODEC Encryption Configurable to support AES-128 encryption or no encryption modes
Hearing Impaired Services
Support TDD support including detection of V.18 including Annex A
Fax and Analog Modem
support DSP based Modem/Fax Tone detection and support for Voice Band Data Mode with auto-
CODEC negotiation and auto-control of echo canceller, jitter buffer, and voice activation
detection (VAD)
Jitter Buffer Support Adaptive dynamically controlled
Latency Control Configurable min / max jitter buffer size
Audio Gain Levels Independently Configurable transmit and receive audio gains
Silence Suppression Configurable VAD with comfort noise generation
Packet Loss Concealment ANSI T1.521-1999
Call Connection Quality
Monitoring RTCP, RFC1889, RFC1890, SNMP MIB for last call quality statistics
Dialing Modes DTMF and configurable pulse dial support
DTMF Relay RFC2833 including fast (40mS) DTMF Relay for alarm system signaling compatibility
Layer 2 Quality of Service ● Full PacketCable secure DQOS with GateID including UGS and UGS/AD
● DQOS Lite support including UGS and UGS/AD
Layer 3 Quality of Service Configurable DiffServe/TOS support for Signaling, RTP, and RTCP flows
Payload Header
Suppression (PHS) Supported for RTP and RTCP packet flows to reduce per-call network bandwidth.
