This coupler, specifically designed for the recording of telephone conversations onto PCs, will operate with any telephone which uses an RJ11 connector for the handset.
The telephone handset is plugged into the RJ11 socket on the coupler, and the coupler is plugged into the telephone using the RJ11 plug on the attached 300mm coiled cable. A three metre cable with 3-pole 3.5mm jack plug connects to the microphone input on the PC or other recording device with similar characteristics.
Note: Recording telephone conversations without the consent of all parties may be subject to regulation or control, or in some countries is illegal, although in the UK calls may, in some cases, be recorded 'for training purposes'. Users should always check before purchasing this device.
