The recorders distinguish incoming and outgoing calls, recognize caller's number and a tone-dialed number for outgoing calls. The information about the recorded calls is stored in a database with their descriptions, date, time and duration. Each recorded call is stored in a separate compressed sound file (.WAV or .MP3 files).

The sound level detection feature allows for automated call recording not only from regular phones, but also from radiotelephones, CB radios and other devices with an audio out.

High sound quality of the recorded calls is ensured with full galvanic isolation between the phone line and the PC, while hardware and software filters are used to correct timbre and differences in volume between the callers.

The recorders need to be connected to a PC through USB and the FonTel application needs to be running to save phone calls to the hard drive . When run unattended in the background, the application automatically recognizes line number, start and end of a conversation, call direction and phone number. It saves all the information to the database and saves the conversation in a compressed sound file. The application can work with an unlimited number of recorders and allows to connect several recorders in a single multiline recording system.

The FonTel L1USB, L2USB and L4USB recorders integrate closely with the FonTel application

The FonTel application is designed to view recorded calls and manage recorders.

The application allows to conveniently browse, search and play recordings and to add notes and comments. It can automatically remove oldest recordings after a predefined periods or when a computer hard drive is full. You can filter the lists of recorded calls by phone line number, day, month or caller number and print or save them to text files according to the criteria selected.

With the application you can simultaneously manage different recorder models. As a result, on one workstation you can view calls from, for example, FonTel ISDN, FonTel L4USB and remotely over the network from FonTel L4NET recorders. It allows to create a flexible call recording system well fitted to your phone lines and setup capabilities.

Caller information

Because caller identification is using the phone book and calls database, the application will show a short information on the caller, ever before the call is picked up. This information includes caller's data (if these are available in the phone book), time and topic of the last conversation, numbering zone (area code or GSM network name) and carrier name. The message will appear in the bottom corner of the screen, even if the application is running in the background and is hidden.
FonTel application can generate any summaries and charts


The application can be used to create any statistical summaries of calls by the number or duration of calls, broken down by the hour, week days, days, months, line numbers, call types (incoming, outgoing).

Backup copy

Enables making backup copies of archived data, including direct burning to CDs or DVDs. Allows for simple browsing of backup copies directly from the application.


If it is necessary to limit the types of recorded phone calls by time and day of the week, you can define recording schedules. A recording schedule allows you to specify, when phone calls of certain types are recorded.

A separate schedule can be defined for each phone line. To define a schedule, specify which call types (all, incoming, outgoing, none, according to sound level2) shall be recorded during a week.

Number whitelists and blacklists1

You can define whitelists and blacklists to specify call numbers to which calls shall and shall not be recorded. You can for example blacklist private phone numbers of your employees to exempt them from recording. You can create unlimited number of lists, for each recorded line you can assign any list specifying whether it is a whitelist (the recorder will record only calls to numbers on the list) or a blacklist (the recorded will record all calls, except for those to numbers on the list).


The application can also work with private branch exchanges (PBX) sharing billing data. This should most of all enable access to information about internal numbers participating in calls, when the recorder is connected to the external exchange.

Answering machine2,3

The answering machine automatically takes the call after a certain number of rings, initiates recording and plays a predefined sound file with a greeting. Recording is terminated at the latest after a certain number of minutes.

Automatic call announcement2,3

The automatic announcement (for example about the fact, that the call is being recorded) automatically plays a predefined recording directly after the call is taken by the incoming call recipient.

1 This feature is not available for the FonTel L4NET recorder.
2 This feature is not available for the FonTel ISDN recorder.
3FonTel L1USB, L2USB and L4USB recorders require a voice modem.

Client-Server architecture

The client application enables remote access from a distant location over a local computer network or the Internet. This allows for a distributed client-server call recording system with one recording station and many clients (for example - one for each phone line).

Web server

The embedded web server provides more options. You can use a Web browser to remotely access recorded calls through a local network or the Internet. It doesn't require any additional software. To connect (using a modem, local network or the Internet) you only need to know the address of the computer recording calls.

Depending on the configuration, you can access a list of calls only or both the list and sound recordings. Remote access can be password-protected.

A calls database and sound files may be located on a network share or drive. This enables centralized call recording from several workstations in a network.

The application can also make backup copies of the archive to a remote computer over a local network or the Internet. In predefined intervals, the application will copy entries from the local call database to an external database using ODBC and will send all sound files to a specified FTP server or will copy the files to a shared folder on a remote computer. The backup process runs automatically in the background. You can store information about calls and calls recorded from different recorders in one place - on a networked server. The same mechanism can be used to enable interoperability with other external systems.

FonTel API allows to integrate the recorder with other software. It enables access to the information about recorded calls.

The FonTel call recording system consists of one or more modules connected in parallel to a phone line and a call recording application installed on a PC. It doesn't require any modifications to the current phone infrastructure - just connect the recorder to a free phone socket, parallel to a phone. It also means that the recorder can be placed anywhere, not necessarily close to the phone. It doesn't interfere with the phone or other devices connected to the phone network.

In case there is no free socket, use a regular phone line splitter.

FonTel doesn't require a power supply and it connects to a USB port of the PC. All necessary cables are included.
