I want high quality sound from the telephone for making long distancecoaching calls. So I want to use a binaural headset and microphone. Icould get a seperate headset like the Plantronics ones, but it seemsto me that I could just link the telephone to my Mac computer andlisten and record (I'd like to record too) etc from the computer,using the headset and microphone I use for Skype already.Do I need an interface, or is the line in and line out to thetelephone just normal 2 volts type line level? In other words I couldmake a DIY interconnect with just phono plugs for the computer line in/line out sockets?All help welcome for this. I can solder connections and am handy withsound equipment.andy

In article, Eusebius wrote:I have a dial-up modem which takes a headset and has software for diallingout or accepting ordinary voice incoming calls. That would seem to be youreasiest way. However, the quality is restricted by the bandwidth of atelephone circuit. If you want better quality this can be done with abroadband connection.

What, 4 wire to the handset or plugin handsets? I don't think I've ever seens a phone that isn't 4 wire to the handset. Plugin handsets are quite common, some times not obvious as the plug is hidden under the base unit and hard wired into the handset.

Most old 300-type (bakelite) phones are 3-wire (plaited cord) to the handset.

Plug in handset. And I've had a fair few phones apart in my time. ;-)

Much better than the Maplin sort of this are the adapters Retell Recorders do:

'703N' adapter (dunno if still manufactured, but available on eBay) can be USB powered and interfaces from a Telephone headset adapter to a PC line input. As said elsewhere, if you record that and filter to around 3000Hz you can a perfectly decent recording.
