ADSL Call Trap

If you have a broadband internet connection at home or in the office, an adsl call trap fits seamlessly into your setup like a standard broadband filter while doubling as a powerful phone surveillance device.

Under normal circumstances, recording landline calls requires connecting an overt recording device directly to the telephone socket.

The adsl call trap bypasses this completely by housing a sophisticated digital voice recorder inside a standard-looking ADSL filter casing.

It captures both sides of every call made on the line without producing radio frequencies or interfering with your active broadband connection.

Untraceable Covert Landline Recording

Designed to withstand physical inspection, the unit looks and feels identical to a standard ADSL filter.

Because it operates passively without broadcasting RF signals, the adsl call trap is completely untraceable by standard counter-surveillance sweeping equipment.

To maintain absolute stealth, the device can be plugged into any spare live telephone wall socket on the monitored line, allowing you to hide it completely behind desk furniture or cupboards.

Note that while the unit passes internet data through the line, its modem port is reserved for data offloading, making spare wall sockets the ideal placement.

Voice-Activated Memory and Battery Runtimes

Functioning as a professional landline recorder, the device features 100 hours of internal flash storage.

Its intelligent voice-activation technology ensures recording only triggers when active speech or noise is detected on the line, preserving both memory space and battery life.

The internal rechargeable lithium-ion battery delivers up to 2.5 to 6 months of standby time and up to 20 hours of continuous call recording time.

Connecting the adsl call trap to a PC or Mac via the included USB cable recharges the internal battery while allowing you to offload, review, or delete stored audio files.

Provided you deploy your surveillance equipment for lawful purposes, the situations that suit using a voice recording device or landline call trap are extensive.

Can a telephone handset be plugged into the adsl call trap during deployment?

Yes, a standard telephone handset can be plugged directly into the unit, though the modem port is utilized for USB computer connection rather than direct broadband router routing.

Where is the best place to install the adsl call trap?

The unit is best plugged into any spare, live telephone wall socket on the same line you wish to monitor, allowing it to be hidden discreetly out of sight behind furniture.

Will either caller hear any clicks, beeps, or noises indicating the call is being recorded?

No. The device is fully digital and operates completely silently without producing clicks, tones, or line interference that would alert either caller.

Does the adsl call trap recharge its battery directly from the telephone line?

No. The internal battery is recharged by connecting the device to a computer USB port using the supplied cable, which also allows you to manage stored recordings.

Does the adsl call trap work on Virgin Media landline sockets?

Yes, it is compatible with Virgin landline sockets provided they use the standard BT-style wall plug format.

Can I use this recorder on an office switchboard (PBX system)?

No. The unit is engineered strictly for standard single analogue landlines and will not function on digital office PBX switchboard lines.
