The TAU-4.IP subscriber VoIP gateway provides the ability to provide modern VoIP services to corporate clients through analog telephones.

Business solution
Thanks to its wide functionality, TAU-4.IP can be used both in the mode of an isolated office mini-PBX with internal switching and a basic set of remote access services, and in the mode of interaction with IP-PBX.

High sound quality
High-performance hardware platform based on a modern Mindspeed Technologies chip, support for all major audio codecs used in VoIP networks (G.711, G.723.1, G.726, G.729), echo cancellation functions, silence detector, comfortable noise generator, reception and generation of DTMF signals, as well as traffic prioritization mechanisms (QoS) ensure high quality voice information.

Reservation
If the main connection to the Internet is lost, it is possible to automatically switch to a backup 3G/4G channel. In the absence of a backup channel, the ability to connect calls between gateway subscribers is retained.

Ease of use
The capabilities of centralized configuration download, intelligent software update and data collection on the status of subscriber devices are implemented in the Eltex.ACS system based on the TR-069 protocol. This system makes it easy to manage your Eltex CPE fleet and reduces network operating costs (OPEX).
