Multiport Access VoIP-gateways TAU series are designed and suitable for voice and facsimile information transmission via the IP-network. Gateways provide customers with high-quality Telephone Communications with Value Added Services Support: call-forward, call waiting, 3-way conference, pick up, group call, call line identification presentation etc.
High quality Voice
The high quality of sound is ensured by the use of the high- performance hardware, support for main audio codecs used in VoIP networks (G.711, G.723.1, G.726, G.729), echo cancellation function, use of silence detector, comfort noise generation, DTMF signals reception and generation and prioritization mechanisms (QoS).
In case of the loss of main SIP server connection, TAU switches to the redundant SIP server automatically with monitoring of service capability of the main one. If there is a connection loss with both servers, local switching among gateway subscribers is saved.
Eltex.EMS management system
A friendly multilingual management interface and support for group management means based on TR-069 and DHCP (DHCP autoprovisioning) enable easy exploitation of unlimited number of TAU on an operator’s network.
Eltex.EMS is a unified management system for monitoring and control of a large number of gateways on a network. The system provides centralized management of a gateway group and its ports monitoring via the unified web interface.
