Description

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).

Redundancy
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.

Usability
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 management system
For gateways mass exploitation on network Eltex offers unified monitoring and control system Eltex.EMS. The system provides gateways group centralized management with the ability of ports monitoring via unified web-interface.
