There is only one way to record every kind of phone, and that way is to use this little Earbud Microphone to record the call.  Simply stick the bud in your ear like any other earbud, then hold the phone or handset up to that same ear, and it will be able to pick up both sides of your phone conversation relatively clearly.  The other end of the Earbud Microphone would plug into the microphone jack of any normal audio recorder - whether it records digital or analog doesn't matter.  This device is universal, and since there is no connection from the Earbud Microphone to the phone it will work with any kind of telephone-like device that you can hold up to your ear.

Sound quality can be improved by raising or lowering the volume of your phone but results will vary, based on changes in phone quality, and ambient noise levels.  This is a condenser microphone so it is not amplified.  It cannot be connected to a computer sound card.
