TAU-8.IP VoIP gateway is an optimal solution for provision of advanced VoIP services to corporate clients via analogue phone devices.
Business solution
Due to the wide functional capabilities, TAU-4.IP and TAU-8.IP are used as an office PBX that provides internal and external routing, as well as a basic set of supplementary services.
High-Quality Sound
A high-performance hardware platform provides high quality of voice data due to support for a standard set of audio codecs used in VoIP networks (G.711, G.723.1, G.726, G.729), voice features (echo cancellation, silence detector, comfort noise generator, DTMF dialing) and traffic prioritization rules (QoS).
Reservation
The devices support automatic switching to a redundant 3G/4G channel in case of failure of the main Internet connection. If there are no redundant channels, local routing between voice ports is available.
Easy-to-Use
Centralized configuration downloading, intellectual firmware update and collection of data on subscriber gateway status can be realized through Eltex.ACS system via TR-069. Eltex.ACS provides simplicity of Eltex CPE management and reduces operating expenses.
