Key AltiServ Characteristics
• AltiServ-to-AltiServ Networking Capability - multiple AltiServ
systems at the same or remote locations can be linked through an IP
network. Also, this feature provides toll savings on long distance calls
by allowing users to dial a remote AltiServ system via an IP trunk and
then the destination phone number through PSTN.
• AltiServ Feature Support - many of the AltiServ features are also
available when using IP trunks. See "Voice over IP Session Support
AltiServ Features" on page 1-24.
• Board ID Support - The board ID of the Triton IP board is displayed
in the AltiAdmin board window. This can be used to relate a Triton
VoIP board to a hardware board.
• DNIS Name Display and Routing over IP Tie Trunk - allows for
DNIS information to be transferred to the system when routed over IP
tie-trunks. DNIS name of matched entry is displayed at AltiConsole,
AltiView, AltiAgent and handset.
• DTMF Remote Carriage - DTMF tones and/or digits are detected
and sent out-of-band, over a reliable TCP/IP channel to the remote
AltiServ, to guarantee the delivery.
• Dialing Prefix Filter - users may select a PSTN or IP trunk when
making outgoing calls by dialing a configurable access code.
• Echo Cancellation - due to bandwidth limitations and device loading,
long delays may occur during packet delivery process, which worsens
the echo effect of recorded and live voice speech. Echo cancellation is
provided to maintain reasonable voice quality.
• G.711 Codec - toll quality (64K) digital voice encoding, which
guarantees interoperability for better voice quality.
• G.723.1 Codec - a dual rate audio encoding standard, which provides
near toll quality performance under clean channel conditions. VAD
(Voice Activity Detection) capability is also included to suppress
silence packets.
• G.729 A+B Codec - speech data encoding/decoding standard of 8
Kbps; the encoder functionality includes VAD, the decoder
functionality is capable of accepting silence frames and generating
comfort noise (CNG).
• H.323 Standard Support - AltiWare IP is based on the H.323
protocol, which is an emerging ITU standard for multimedia
communications over IP.
