calls.
You must always check that the number of channels that you require is
installed. When insufficient channels are installed an upgrade up to the
maximum channel count for the model that you have can be ordered
from your dealer.
The Call Recorder PRI always has an internal drive and a network
interface.

1.1
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.

Speech Compression
Call Recorders that have compression facilities on board compress
recordings according to the G.723.1 format. G.723.1 compression has a
good balance between audio quality and recording size and can be
reproduced on most PC’s with Microsoft Windows versions. Compressed
recordings take up 1/10th of the size of uncompressed recordings (800
bytes per second against 8000 bytes per second). Therefore the
compression has a profound effect on the storage capacity of the Call
Recorder in terms of recording time.
