To record calls over PSTN channels, such as ISDN30 (PRI/E1/T1/J1), ISDN2 (BRI) or analogue POT lines, a piece of physical hardware - the Magic Box - is required, in addition to the Echo software.

The Magic Box can be attached to any telephone system connected to one of our call logging solution, TIM Plus or Enterprise. The box is placed between the ISDN trunk and the telephone system and must be connected to the PC running the Echo software, where the audio files will be stored and embedded thereafter in the call logging software.
