10  The Call Recorder as a Normal Recorder 
The Call Recorder can be used as an audio-recorder at any time, with the 
same high capacity it has when recording telephone calls. If you are 
conducting a normal conversation, for instance, and the headset is on the 
rest, just press the recording button, and the conversation will be recorded. 
Note: The Call Recorder cannot operate as a telephone or call recorder while it is recording through the microphone.  
Experience has shown that the Call Recorder is mainly used as an audio-
recorder in meetings, to facilitate note taking. 
Automatic Volume Control and the Microphone 
A striking feature of the Call Recorder is that it will automatically adjust itself 
to a weak signal level. This is asking a lot of the Call Recorder, because 
when it functions as a phone the microphone has to cope with a voice 
speaking right into it, whereas when it is recording meetings people may be 
quite a long distance away. Although the automatic volume control of the Call 
Recorder is extremely good, it is advisable to purchase a separate table 
microphone if the recorder is often used for meetings. The quality of 
recordings via the headset microphone is more than adequate for occasional 
use. 
10.1 Recording 
Recording is started by simultaneously pressing the Record and Play keys. 
The display will show: 
Recording Microphone!
19-08-01 10:59 00:00:53
The time counter can be seen to move during recording. 
Recording is paused by pressing the Play key. W hen the Play key is pressed 
again, recording will continue, while the Stop key stops recording. Next, you 
can indicate whether you want to STORE the recording or DELETE it, by

decide this in; if you do not, the recording will automatically be stored.   
Searchcode: _______
STORE 55 DELETE
If the Play key is pressed in this situation, the recording can first be listened 
to, and deleted or stored later. 
On a hard disk model deleted  recordings  can still be retrieved by pressing 
the Play key first, followed by 
, and then be stored after all; it is only really 
erased when a new recording is started (message, recording or call). The 
recording can be saved under a search code selected by you.  
10.2  Search and Play 
Searching and playing microphone recordings is identical to searching and 
playing recorded telephone calls. Press 
 to see the following display: 
Playback Mic. Records
SEARCH LAST STOP
From here on follow the guidelines for searching and playing recorder 
telephone conversations.

11  The Network Interface  
Every Call Recorder has been provided with a 10BaseT Ethernet interface. 
This type of interface is the most common one for local area networks and 
connection to the Internet. 
The protocol chosen for communication via the Network is TCP/IP, the 
Internet protocol that can be used on most local area networks. 
11.1 The possibilities 
The main reason for developing the network interface is to offer the possibility 
to centrally archive the recordings, or to make a back-up copy of the 
recordings. The biggest advantage of the network interface is the high 
transport speed of big audio files, another is that they can be retrieved both 
via the internal network and via internet. There are other possibilities, 
however, and these are listed below: 
-  Smallscale archiving from 1 to 4 recorders onto a PC in the network with 
the help of the Call Recorder Archive Software 
-  Bulk archiving for a larger number of recorders with the help of the Call 
Recorder Server application (expected to be available mid 2001) 
-  Archiving by own applications with the help of FTP. The recorder works 
as a normal FTP server. 
-  Remote configuration by system managers via the Telnet protocol 
-  Audio monitor function; recordings can be listened to remotely via the 
loudspeakers of a PC  
There are various ways in which the connection can be made, so that it is 
almost always possible to archive or listen remotely. The various possibilities 
are discussed below, from very simple to very elaborate. 
•  Connecting one PC with one recorder is possible by supplying the PC 
with a networkcard and connecting the PC via a special (crossed) cable. 
An even simpler way is to replace the networkcard by a USB to Ethernet 
adapter, available as a cable. They result in a very fast connection 
between the PC and the recorder.  
						

							Call Recorder Manual ©-2001 Vidicode Datacommunicatie BV  74  •  Connecting a PC with various recorders in the same building is possible 
by connecting all recorders and the PC onto the local network. 
•  A good example of a simple solution to get access to a number of 
recorders on a distant location is to work with an ISDN router with hub, 
as provided by several manufacturers such as Cisco or Intel. The 
recorders are connected to a hub, and a PC with our archive software is 
connected to the hub via its ISDN software. 
•  In a large scale application PC’s and recorders are connected via the 
internet or an intranet.  
11.2 Configuration 
Configuring the network function of a Call Recorder for local use is not 
especially difficult, although within a company environment it is advisable for 
the network manager to enable the network function of the recorder. He is the 
person best suited to judge how the recorder should be configured to function 
properly with the other systems on the network.  
The remote use of the recorder via the Internet or an intranet is less simple. 
The system manager should allow for the interaction between the recorders 
and the router/gateway/firewall combination that connect the local network 
and the wide area network. 
To enable the network, look in the configuration menu for “network settings”. 
Network configuration will involve the following questions: 
Network active: Yes
NEXT CHANGE BACK
If you do not use the network, the answer here should be “No”. The next 
question concerns FTP, which can be used for  archiving, for example. 
FTP active: Yes
NEXT CHANGE BACK
W hen FTP is not used the answer to this question should again be “No”. If it 
is used, there are two follow-up questions:  
						

							Call Recorder Manual ©-2001 Vidicode Datacommunicatie BV  75
FTP ID: 0000
NEXT CHANGE BACK
This is the ID a user should give to approach a Call Recorder via FTP. There 
is only one possible ID. 
FTP code: XXXXXXXX
NEXT CHANGE BACK
The access code for an FTP session. The default setting is 0000.  
The next question concerns a property of your network: 
Use DHCP Server Yes
NEXT CHANGE BACK
If there is a DHCP, server, the recorder will automatically be assigned an IP 
address (network address), in which case any application called up by the 
recorder will ask for the IP name of the recorder. If DHCP is not available the 
user will have to give an IP address himself, which will be used by any 
application approaching the recorder: 
IP addr: 168.102.000.012
NEXT CHANGE BACK
In an application with linked networks without DHCP server there will not only 
be a question about the IP address, but also about the IP subnet mask: 
IP mask: 255.255.255.0
NEXT CHANGE BACK
The IP subnet mask is only applicable for access to recorders via an Internet 
or intranet. Normally you will not have to change this setting.  
						

							Call Recorder Manual ©-2001 Vidicode Datacommunicatie BV  76  If there is an IP subnet mask, there will be a gateway to the other network as 
well, and the address of this gateway will be filled in. This should also be 
done if there is a DHCP server. 
Gateway: 0.0.0.0
NEXT CHANGE BACK
If the gateway is not applicable in your situation, you do not change anything.  
If DHCP is used, the address mentioned here has come  from the DHCP 
server and  the name found in the next question will be used : 
IP name: CRPeter
NEXT CHANGE BACK
Access via Internet on a network with several FTP servers, e.g. several Call 
Recorders, can pose problems for the router if the IP port for all FTP servers 
is the same. If that is the case, it may be necessary to set a number in 
addition to the common value of 21. In all other applications the default value 
of 21 should be maintained. If a different value is set the system manager 
should take care that there is no conflict. 
IP Server Port: 21
NEXT CHANGE BACK
 
The next question concerns the use of the monitor function (Listening in via 
the network). 
Monitor active: Yes
NEXT CHANGE BACK
If the monitor is active, it allows you to set the accesscode for the monitor 
function.

11.3  Use of the network interface 
The network functions are important for applications that use the network for 
communicating with the recorder, such as the Call Recorder Archive Software 
and the Call Recorder Monitor Software. 
11.3.1  The FTP protocol  
FTP is the standard method to ask for files via the Internet, which explains 
why there is a lot of software that can retrieve the files of your Call Recorder. 
This possibility is mainly of interest to developers, however. 
Our Call Recorder Archive Software will be of more interest to the Call 
Recorder user. In order to be able to use the archive software, the network 
functions and FTP should be enabled. Depending on whether there is a 
DHCP server present in the network, the IP address or the IP name should be 
given as well. W hen both the PC with the software and the Call Recorders 
are connected to the net, all recordings will be archived at a very high speed 
via the LAN.  
The use of Call Recorder Archive Software and the installation of it on the PC 
are explained in the helpfile that comes with the software. 
11.3.2 The monitor 
The monitor protocol of the Call Recorder is not standard. For this reason the 
monitor is of special importance for users of the Call Recorder Monitor 
Software option. 
To use  Call Recorder Monitor Software the network needs to have been 
enabled and the IP address or IP name given. The monitor function should 
also be operating. The PC with the software will then be able to select from 
the recorders present and to listen in to the conversations via the 
loudspeakers or headset.  
The use of Call Recorder Monitor Software and its installation are also 
explained in the helpfile that comes with this software.

12  The Crypto Card option 
The Crypto Card is, along with the Archive Software, the most important 
option of the Call Recorder. Every Call Recorder has been provided with an 
IC card reader. If a set of Crypto Cards is purchased, the recorder will 
automatically be able to work with them. 
12.1  How a Crypto Card works 
The Crypto Card works as follows: 
•  All recordings that are made while the Crypto Card is inside the computer 
are coded. These recordings can only be played if one possesses a card 
from the original set. 
•  Recordings are uniquely recognizable by the card number. 
•  The card has been safeguarded against playing with a pincode or, if this 
has been lost, with the PUC (Personal Unlock Code) provided at delivery. 
As we have already seen, it is possible to configure the recorder in such a 
way that recording can only take place with the card. 
The function of the card is as follows: 
•  Users who keep their cards with them can be sure that their recordings 
cannot be listened to without their approval. 
•  It is safe to transport recordings via the network or Internet, because they 
cannot be listened to without a card from the original set. 
•  If the monitor function is used, the card also protects this function against 
unauthorized listening in as well, so that it is safe to listen to a 
conversation via Internet. 
•  It is possible to let more than one person use the same recorder without 
any of them being able to listen to the recordings of the others. If 
necessary, the central archive can clearly indicate which recordings were 
made by whom.  
						

							Call Recorder Manual ©-2001 Vidicode Datacommunicatie BV  80  This method of protection is similar to the protection of telebanking via 
Internet and the risk that this form of protection is broken is very low.  
12.2  Changing the card code 
The card code (PIN code of the Crypto Card) is only used when playing 
recordings made with the Crypto Card. Select the option “Changing the Card 
Code” from the settings menu. The recorder will first ask for your present card 
code: 
Card code: XXXX
CONTINUE STOP
Now the new card code can be input: 
New card code: XXXX
CONTINUE STOP
The code then has to be entered once more as a check: 
Repeat code: XXXX
CONTINUE STOP
Then the display will show: 
New card code accepted
STOP
If the wrong code has been entered three times running, the recorder will 
automatically ask for the PUC. That will start a similar procedure with which a 
new card code can be entered.  
The PUC code must be entered correctly. Entering an incorrect PUC code 
five times running will lead to the card being made invalid.
