TRX-20-35B Telephone Recording Jack (3.5mm) TRX20
These WILL NOT WORK with CORDLESS PHONES.
The TRX-20-35B Telephone Record Unit (specifically for 3.5mm mic inputs) adapts a recorder to both single or multi-line telephones. Simple and easy to use, this unit connects quickly between your telephone and handset providing crystal clear audio recordings. (The audio quality will be as good as the audio coming through your handset!).

A modular connector simply plugs between handset cord and the telephone, and 3.5mm jack plugs into your recorder.

When used with a multi-line phone, it will record whichever line you are talking on.
3.5mm microphone input plug on the tape recorder or digital recorder.

   I had a need to record interviews taking place via phone for some academic research that I’m conducting. This is an excellent solution, and very easy to use. I work at a university, on the university’s digital phone system. Because this plugs in at the handset, it can be used, I would presume, on any network, digital or analog. It can’t be used with a cell phone that I can see, but for traditional phones, you could not beat this item.

   I am currently recording conversations on an Olympus DS-30 Digital Voice Recorder Olympus DS-30 Digital Voice Recorder. Of course, consult local and state laws regarding required disclosure the legality of recording phone conversations.

   This interface plugs into the same jack as the headset and not the main line. At first this was confusing. However, once I figured that out all went well. The sound quality was as good as the phone receiver and it was easy to use with my laptop computer. For the cost, this was an unbeatable solution to the problem of recording meetings in an efficent and easy way.
