TAU-72.IP/TAU-36.IP Universal Network Terminal 13
2.
Distributed mini-PABX mode
In this case, the device acts as a mini-PABX that is able to access other
gateways (TAU-32М.IP, ТAU-72.IP, etc.) and Softswitch using SIP/H.323 protocols. The device allows for
unassisted processing of supplementary services, call routing, see Fig. 2.

Product Design and Operating Principle
Subscriber voice signals are served to audio codecs of subscriber units, where they are encoded using one
of the selected standards, and then sent as digital packets to the controller via internal backbone. In addition to
voice signals, digital packets contain control and interaction signals.
