1.1 Product Overview
TAINET VENUS 29xx Series, a critical part of the Next Generation Network (NGN),
functions as an interface gateway unit between the traditional Public Switched
Telephone Network (PSTN) and the IP packet network by performing the
conversion of the analog voice traffic to/from the IP-based media stream.
VENUS 29xx Series is a Voice-over-IP (VoIP) Gateway that provides cost-effective
and quality voice service over global IP packet network (Internet or Intranet) for
end-users, and, in the meanwhile, lower the installation and maintenance effort.
With analog voice interface connecting to user‟s existing telephone handset or
PABX, and the Ethernet interface connecting to the service providers' IP network,
VENUS 29xx Series bridges the PSTN and IP network.
Depending on the installed firmware, VENUS 29xx Series supports Session
Initiation Protocol (SIP), Media Gateway Control Protocol (MGCP) and MEGACO
which comply with IETF RFC 3261, RFC 3435 and RFC 3525 respectively. This
document is only for VENUS 29xx Series installed with SIP firmware.
VENUS 29xx Series allow traditional PSTN users to make phone calls over the
Internet without changing their telephone operating procedure. Using a Proxy
Server or SoftSwitch together with the VENUS 29xx Series, service providers or
telecom companies are able to provide integrated voice and data service over the
IP network to their customers. Features like billing, accounting and network
management supported by the SoftSwitch are available as well.
