Time Division Multiplexing Expert in Call Center Technology

Case Description:

A Time Division Multiplexing (TDM) expert was sought for a patent infringement case involving digital audio technology for call recording. TDM is a type of digital audio technology in which two or more signals or data streams are transferred apparently simultaneously as sub-channels in one communication channel, but physically are taking turns on the channel.

IMS ExpertServices was asked to provide a digital audio expert in time division multiplexing and IP-based telephony switches to consult on software applications for call centers and compliance recording utilizing computer telephony integration, or CTI. Most call centers use PBX - ACD systems which are TDM based.
