VoIP Gateway TAU-24.IP
Mass production
Key features
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.
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.
- Office PBX functionality
- High-quality sound
- Current and voltage port protection
- Measurement of subscriber line physical parameters
- The maximum length of line – 6 km
