lawful interception

Law Enforcement

Using BTT Voice Logging applications Law Enforcement Agencies can do almost any kind of call and radio interception starting from a single tiny wire-tap to a full-scale corporate E1 digital trunk interception. BTT Voice Logging applications decode signals such as DTMF dial tone, Caller ID, and CCIR radio codes, and demodulate Fax transmissions.

With BTT Voice Logging applications you can:
- Instantly playback the conversation
- Listen to live conversations
- Intercept Fax transmissions
- Intercept corporate E1 lines using DUMAN E1 boards
- Remotely access the voice logs and live conversations

Implementation Examples

Telecom operator supported wire-tapping

According to a warrant your local PSTN or mobile operator can provide you with a copy of the monitored person’s phone communications. Depending on the nature of the provided telephone link you can record the analog communications using a number of DUMAN MC8 PCI boards and record digital E1 trunks using DUMAN E boards.

Mobile voice logging

Let your squads go mobile. When a specialized voice logging is required you can record communications using a laptop computer and a DUMAN MC4 USB box attached to the desired telephone line or radio scanner.

Radio transmission interception

In order to record Radio communications you can attach a DUMAN MC8 PCI board to a radio scanner and intercept all radio communications. BTT Voice Logging systems will automatically decode CCIR Tone-5 or other radio equipment codes.
