This ADSL Filter Landline Call Recorder offers an easy, maintenance free concept to record both incoming and outgoing telephone calls in digital WAV format.  Simply plug the ADSL Filter into a spare telephone socket within the home or office to automatically record all calls on the telephone line.

Whatever your reasons may be, telephone recording within your own property and of your own calls is legal and should be used as a way of providing vital audio evidence to protect your integrity.  The ADSL Filter Landline Call Recorder is ideal for the average user who wishes to record their calls with minimum fuss.

More Information
What is an ADSL filter?  What is it's normal functionality?

I already have an ADSL filter plugged into my BT telephone socket, can I replace it with the call recorder ADSL?

If you attempt to replace an existing ADSL filter (which gives you both internet and telephone), for this call recorder filter, then whilst it will work to record the calls it will disconnect the internet.  You can really only use this filter to replace an existing filter if you use the telephone only.  Otherwise, plug this ADSL into a spare telephone socket elsewhere around the home / office.

Are the telephone recordings clear?


Please Note: This ADSL filter will not cause any interference or noise on the line to which it is connected however, the close proximity of components within the recorder may cause slight static on the recorded audio files but will not adversely affect the audio recording quality.

No.  The ADSL telephone filter for Plug & Play simplicity.  There is no complicated setup procedure and no technical skill required.

Does it record both sides of a telephone call?

I need to prove my side of events for evidential purposes, will this device help?
