Basic Functions
The Call Recorders PRI is designed for continuous unattended recording. All
recordings are stored digitally on the internal drive. The large storage capacity of
the drive ensures the ability of the Call Recorder of long term unattended
recording.
The Call Recorder issues a warning when the internal drive is getting full. If the
warning is ignored the oldest recordings will be overwritten by the newest.
Stored recordings can be accessed on PC’s via the LAN using the optional Call
Recorder Access Software ro Araña web interface.
You can copy recordings from the internal drive to CD if your Call Recorder is
equipped with a CD drive. Copying recordings to CD-recordable can be done in
different ways for different purposes. It is possible to copy single recordings, copy a
selection of recordings or automatically copy all new recordings. Recordings on CD
can be viewed and played with the Quick CD Access software that comes with the
Call Recorder with CDdrive.

Therefore the compression has a profound effect on the storage capacity of the
Call Recorder in terms of recording time.
