Questions on the EyeSDN USB software and the call recording service

Must the program "Call Browser" always be open or activated manually in order to begin recording data?

No. The EyeSDN devices are set to automatically record and store data by default. As soon as the computer to which the device is connected is turned on the device begins recording. The Call Browser program does not have to be open permanently.

What do I need the Microsoft dotNet (.net) Framework for?

The Microsoft .net Framework program is required to use the "Call Browser" and the "Interactive Client" programs. It is installed together with the Call Browser and Interactive Client, if you have chosen to install these programs.

The software has been installed as instructed, but I receive the "..Microsoft "dotNet" Framework® is not loaded" error message when I try to open the Call Browser program.

If the Call Browser has been chosen for installation when installing the software, the Microsoft ".net" Framework program will be installed automatically. Before it is installed, the computer is checked to see if this program is already present, and if so, the program will not be installed. Under certain circumstances this verification may fail, and you will need to install the program ".net" manually. Insert the CD provided into the computer and choose either the program dotnetfx_eng.exe or dotnetfx_ger.exe from the 'third parties' folder, depending on whether the English or German language version is required. A double click will start the installation, and after the restart the Call Browser should open itself automatically, with no error message.

Why is one of the conversing parties quieter than the other when replaying recorded calls?

The EyeSDN USB devices create a digital copy of telephone conversations held over the telephone line. The recording device has no influence on the quality of the conversations, performs no compression and undertakes no changes. The causes of this problem may lie with either the recording (i.e. one of the two telephone microphones is quieter than the other) or the playback (soundcard, speakers, Media Player settings). We also recommend that you check your speakers.

I changed the storage directory and now I don't see any calls in the Call Browser.

If you have chosen a device-specific storage directory you have to change the directory in the Call Browser's Settings/Directory menu. This is important since otherwise the Call Browser will not show any saved recording files. The Call Browser reads saved recording data from the storage directory which is created by default during the software installation. You will find the standard storage directory in configuration dialogue in field "Storage Directory". If you change the storage directory for the connected device no data will be saved in the standard storage directory. Therefore you have to specify the changed storage directory in the menu Settings/Directory. That means you refer to the device-specific storage directory in this dialogue.

I have renamed the call files. Why does the Call Browser no longer display them?

The Call Browser only displays those calls that are stored in the same format as the one in which they were generated during recording. This allows the details to be entered into the proper columns. If the file name is changed, the file may be opened directly from the storage folder or through the File/Open tab folder of the WAV player.

What is the TCP port number in the configuration window for?

The TCP port number is not an IP address, but rather the port number of a TCP server port. This allows the recording service to be accessed remotely using client specific software. Integrators can be supplied with the network interface specifications. The network interface is deactivated if this value is set to zero.

How do I establish a network connection with the computer to which the EyeSDN USB device is attached?

This function requires that the PC to which the EyeSDN USB device is attached (the recording computer) be connected to a network. Open the "My Computer" dialog window on the external computer and choose the option "Map Network Drive"' from the "Tools" tab folder. Enter both the drive letter and the path of the recording computer and establish a connection. This gives access to the data and programs on the recording computer.

Which protocols are supported by Wireshark?

Wireshark can decode the Q.921/Q.931 (DSS1) ISDN protocols, the PPP/LCP/CCP protocols and all other IP protocols which are based on these.

Which settings do I need to apply so that only the voice of the caller (such as the agent) is recorded?

An ISDN connection has two terminals, the NT (network termination) and the TE (terminal equipment). Both sides broadcast an audio stream. Outgoing calls begin at the TE terminal. Your desired setting can be applied in the Call Browser. To do this, call up the serial number of the EyeSDN USB device in the Call Browser in the menu under Settings/Devices and click on "Edit". In the new window, "Configuration of device", the B Audio Format may be changed in the centre panel. Choose the audio stream you would like to record, G.711 NT or G.711 TE, from the list.
