Speech Compression
Call Recorders ISDN 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.
Therefore the compression has a profound effect on the storage
capacity of the Call Recorder ISDN in terms of recording time.
Real time compression while recording many channels requires a lot of
extra processing power and therefore extra hardware in the form of
very fast processors.

Network
The Call Recorder ISDN features an Ethernet interface. The Call Recorder
ISDN can be connected to a PC or computer network through the
Ethernet interface. With its own IP address the Call Recorder ISDN acts as
an FTP-server from which recordings can be downloaded using any FTP
client. The Call Recorder Access software can be used to connect to the
Call Recorder ISDN over the network to retrieve recordings and archive
them on the PC. The Call Recorder Access software has extensive
archiving capabilities including the creation of special archives suited for
backup on CD. The Call Recorder Access System allows for fax image
recovery of recorded fax transmissions.
The Call Recorder can e-mail its status in case of a malfunction.
Recordings can also be emailed according to the extension\e-mail list.
Yet another application of the Ethernet connection is Real Time Remote
