The Apresa is a versatile call recorder that is able to record a large number of TDM telephone calls simultaneously, up to 24 channels per inserted PCI-e card. It stores the recordings on its own hard disk(s).

Important: In some cases you can record from TDM phones using VoIP recording. In this case Apresa records from a PBX where TDM phones are connected too. See the picture below, showing Active Recording in general.

When Active Recording is used the Apresa receives call data, including the audio stream, because it takes part in the call as a third party. The PBX needs to be configured to make this possible. See the CSTA solution for the Avaya Aura in the picture below. The DMCC protocol is used. Note the TDM phone connected to the PBX.
