VoIP Gateway TAU-4M.IP

TAU-4М.IP are VoIP gateways intended for connecting analogue telephones and facsimile sets to an IP network. The service is provided via a converge data transmission network, where different IP-PBX systems can be used as a switching node.
 

Fax transmission

Transmission of facsimile messages is implemented by means of audiocodec G.711 pass-through and according to T.38 protocol.
 

High-quality sound

A high-performance hardware platform, support for all basic audio codecs used in VoIP networks (G.711, G.723.1, G.726, G.729), echo cancellation functions, a silence detector, a comfort noise generator, DTMF signal reception and generation, as well as traffic prioritization mechanisms (QoS) provide high quality of voice data.
 

Redundancy

In case of a primary SSW connection loss, the device switches to a redundant SSW and monitors the state of the primary one. If the device loses connection with both IP servers, calls between local subscribers still can be switched.
