The date can now be changed, either by filling in the exact day, or by typing in a * 
for day, date and year. The following selection will give you all the microphone 
recordings from March 2001. 
Mic.recs from **-03-01SEARCH CODE STOP
Now either press the ‘SEARCH’ softkey straightaway, or fill in further search 
criteria, with the possibility of continuing to the CODE key.    
The CODE Search Key     
The CODE search key is unique to microphone recordings. Earlier on, in 4.2 you 
have seen that it is possible to type in a code, when stopping a recording.   
The first recording of the selection made will be displayed, as will the total number 
of recordings found.         
20-06-01 11:26 1/25SEARCH CODE STOP
The   and  keys allow you to scroll backwards and forwards in time 
through the selection made, until you have found the recording you want.        
The recordings can be played with the 
 key.      
The user can change the CODE search key  at a later moment. In this respect 
‘CODE’  differs from the other search criteria.  
4.4.2  Playing the microphone recordings 
See the instructions in 4.3.2 about playing call recordings, as the procedure is 
exactly the same.

4.5  The DISK key 
The Call Recorder is meant for continuous automatic recording. The hard disk will 
be written to until it is full, at which point the oldest recordings will be 
automatically overwritten. If compression has been switched on, this will perhaps 
only be after several years of continuous usage. Of course this depends on the 
number of calls and the capacity of the hard disk. 
The disk function key 
 can be used to retrieve information about the contents 
of the hard disk in the recorder. 
Free: 1032(7772) HoursNEXT STOP
Two numbers are displayed, i.e. the space without compression and the space 
with compression.   
The next display is of special importance if the disk is ever full up.   
Oldest record.: 01-11-00NEXT STOP
As has been said before, when the disk is full, the oldest recordings are 
automatically erased. This information enables you to determine whether that is a 
problem.  
The third function informs the user of the total number of recordings on the hard 
disk. This is the total of recordings from both sources: telephone lines and 
microphone. 
Total recordings: 14325STOP

4.6  The Monitor  
De monitor makes it possible to listen in to conversations via the recorder. While 
the recorder is in use, the display will indicate which lines are engaged, e.g.:  
Monday 10-12-01 14:011> 2< 5< 7<
If you wanted to listen in to the incoming call on line 2, you would press the 
Monitor key (
).  
The display will show:  
Line Monitor(press 1-8) STOP
Now press the number 2. From then on you can listen in to the call on line 2. You 
stop the listening in by pressing the ‘STOP’ key (
). 
Once activated, the monitor function stays active with every other call on the 
same line. Therefore the monitor always needs to be switched off manually.

5  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. 
5.1 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 
optionally available Call Recorder Archive Software can be used for archiving a 
maximum of 4 recorders.     
The biggest advantage of the network interface is the high transfer speed of big 
audio files, another is that they can be retrieved both via the internal network and 
via the Internet. There are other possibilities, however, and these are listed below: 
-  Archiving by own applications with the help of FTP. The recorder works as a 
normal FTP server. 
-  Audio monitor function; recordings can be listened to remotely via the 
loudspeakers of a PC 
-  Remote configuration by system managers 
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 use a USB to Ethernet adapter, available as a cable. They 
produce a very fast connection between the PC and the recorder. 
•  Connecting a PC with various recorders in the same building is possible by 
connecting all recorders and the PC onto the local network.  
						

							 
                 
                 Call Recorder ISDN Manual - ©2001 - Vidicode Datacommunicatie BV
  36  •  A good example of a simple solution to get access to a number of recorders 
at 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.  
5.2 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 or she 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. 
Press the  
 key to configure the network. Please keep in mind that it is not 
possible to configure the network whilst recording. The key will not react in that 
case. For network configuration the following settings are available:      
Network active: YesNEXT 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: YesNEXT CHANGE BACK 
						

							 
 
       Call Recorder ISDN Manual - ©2001 - Vidicode Datacommunicatie BV                   
37 
When FTP is not used the answer to this question should again be “No”. If it is 
used, there are two follow-up questions: 
FTP ID: 0000NEXT 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: XXXXXXXXNEXT CHANGE BACK
This is the password for a FTP session. The default is 0000. 
FTP Server Port: 21NEXT CHANGE BACK
Access via the 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 as an 
alternative 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. 
The next question concerns a property of your network: 
Use DHCP Server YesNEXT 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:  
						

							 
                 
                 Call Recorder ISDN Manual - ©2001 - Vidicode Datacommunicatie BV
  38 
IP addr: 168.102.000.012NEXT CHANGE BACK
If DHCP is available, there is no opportunity to change the IP address manually:                      
IP adrs: 168.102.000.012NEXT 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: 255.255.255.0NEXT CHANGE BACK
The IP subnet mask is only applicable for access to recorders via the Internet or 
intranet. Normally you will not have to change this setting. 
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: 0.0.0.0NEXT 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: CRPeterNEXT CHANGE BACK
With most networks with a DHCP server it is possible to call the IP name of the 
recorder, rather than the IP address. In that case it might be worthwhile to change  
						

							 
 
       Call Recorder ISDN Manual - ©2001 - Vidicode Datacommunicatie BV                   
39 
the IP name into an easily remembered name such as CR-Peter. You should 
always do so if it is possible to call  the recorder with the IP name.  Only if it is not 
possible to call the recorder with its IP name, even though a DHCP server is 
being used, should the IP address used to approach the computer be read from 
the display of the recorder.              
The next question concerns the use of the monitor function (Listening in via the 
network). 
Monitor active: YesNEXT CHANGE BACK
If the monitor is active, it allows you to set the accesscode for the monitor 
function. 
Monitor code: XXXXXXXXNEXT CHANGE BACK
5.3  Use of the network interface 
5.3.1  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. When both 
the PC with the software and the Call Recorders are connected to the net, all 
recordings can 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.

  40  5.3.2 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.
