Once installed, CRU2 and the supplied CRS software will automatically RECORD your telephone calls and save the call recordings in a nominated folder on the local PC or on a Network or Server drive.  Call Recordings can be autonamed and/or stored by time and date.

You can also enable or disable the injection of 'recording tones' into the telephone call, to advise your callers that the call is to be recorded.

Telephone calls are by default saved in MP3 format, which minimises memory usage and facilitates easy replay, storage and email transfer.
