Analog Telephone Adapter for Split The Line to Telephone and Voice Recorder, with Two RJ11 Port for Incoming and Outgoing Phone Connection and 3.5mm Audio Socket to Connect to Voice Recording Device

This method is really going back a bit in history, but it does work, with some caveats. First, I have VoIP system. No problems there, but you do need your standard POTS phones, RJ11 plugs, and cables. It's easy enough to hook up. I recommend doing some test recordings. I am using a OM WS-883. That's an Olympus digital handheld recorder. Tip: Power it on and just leave it until it shuts itself off after a few minutes. Then, when the phone rings, and you wish to record the call, just press the RECORD button. The unit will fire up and start recording within 6 seconds or so (about 1 to 2 rings). This semi-off mode does not affect the battery. The unit starts up much faster and starts to record immediately. Recorder settings are important! This device records in MONO. The WS-883 is a stereo unit. My first important recording had a hum noise that I didn't notice when played back through the recorder, but was very evident when downloaded to the PC and played. There was a lot of hum in the background. There was not enough to jeopardize the recording, but it was annoying. There had to be better way. Here's the way: Set the WS-883 to 64 kbps MP3 MONO (the best of the MONO settings) under Recording Mode in the Menu. Skip down the menu to Low Cut Filter and turn that ON. The recordings will be crystal clear on BOTH sides of the conversation. I am sure other recorders have similar settings. I suspect setting your recorder to record in MONO will solve most of the hum problem. The file transfer via USB-A was a piece of cake. Plug it is and it is a drive. Drill down to the folders on the WS-883 and there is your .mp3 file. Just copy that over to your PC. This unit was well worth the price. I would buy it again.

Although the device comes with a stereo (TRS) 1/8" cable, the audio jack on the device is wired as mono (TS), which means that if you hook this into a recorder, one of the channels will have a constant buzzing noise because it's hooked to ground. The actual phone audio will be on the other channel, and the noise floor isn't great, so you'll likely have to use a notch filter to remove some power line frequencies (and their harmonics). You're probably better off getting a device with output jacks designed for a tape recorder (there are a fair number of new old stock ones out there), or if you plan on recording a lot of calls, one of the higher-end digital devices.

Doesn't work, returning it.

Easy way to record on PC from traditional phone line. (Like any phone recording, check local laws.)

This is one of those items that either works or it doesn't. It works. Full-stop. I do freelance newspaper reporting, and it's incredibly valuable to save myself the trouble of scribbling or typing notes while having a conversation. Also, whenever a company says, "This phone call may be monitored..." that means they're giving *you* permission to record it. IMPORTANT: About 38 states allow you to record someone without informing them; a dozen require "two-party notification." Before you record someone without telling them, check with recordinglaw.com to see if it's allowed.

Cool little phone jack adapter for recording calls with an external recorder. Sometimes I participate in Xoom video conferencing meetings by calling in on my home phone. Have a nice hands-free office speaker phone I enjoy using. Now I can covertly record the entire Xoom session on my mini voice activated recorder. Only need connect a 3.5mm cord to the audio out port on the telephone jack and audio input port of my recorder. Normally you're not able to record Xoom meetings on the app without the host’s permission. Now I'm able to keep notes on informative product demonstrations, Church service, and state chapter meetings I’m involved in thanks to this ingenius telephone line adapter. Sound comes through crisp and clear on the recording. Use a product called Total Recorder to manually edit the completed audio file on my Windows 11 PC. I add chapters, remove excess silence, and improve quality by increasing the bass etc. Nice little hack to easily record phone calls.

Great to use when you are taking down directions or instructions . Connect's to your desk phone easy. Then plug it into your pocket recorder. And take the directions or instructions to the job. Better than writing it down.
