TAU series multiport subscriber VoIP gateways let you send voice and fax data over IP networks. They provide high-quality phone service with standalone office PBX and various VAS support.
The gateways have a strong hardware platform and support all major VoIP audio codecs (G.711, G.723.1, G.726, G.729), echo cancellation, silence detector, comfort noise generator, DTMF signals, and QoS mechanisms for clear voice transmission.
The gateways can switch to a backup SIP server and monitor its status if the main one is disconnected. They can also keep local communication between subscribers if both IP-phone servers are down.
The gateways have a simple multilingual interface and support group automated management based on TR-069 and DHCP (DHCP-auto provisioning) protocols for smooth operation on the operator’s network.

For large-scale network deployment of gateways, Eltex offers a unified monitoring and control system Eltex.EMS. The system allows centralized management of a group of gateways and port monitoring through a single web interface.
