3. DESCRIPTION

3.1 INSTALLATION

The program of installation places the recorder and the reader in a specific directory. For more information, it is necessary to read the manual of installation Ref 1. When you restart your installation, the Recorder VOIP software is executed automatically. The read again program should be executed manually.

3.2 RECORDER

3.2.2 PRINCIPLE

The VOIP recorder allows to recording all phony communications which are active on the LAN network between the TETRA SWITCH system and the operators post. A daily backup is automatically executed. The software ensures an automatic purging of these files not to saturate the backup function. A manual backup of the whole or a part of the communications can be executed by the user. If the number of communications is too big, several recorders can be connected. You have just to configure them so that the communications are distributed correctly. The Ref 1 manual describes the process. The connexion with the VOIP reader completes the device and allows the read again of the old communication or the direct read again of a communication in progress. For reasons of confidentiality and security, this program can be installing without VOIP reader.
