Hello,

I am looking for a "telephone patch", or something similar. I'm not into
radios, and the application has nothing to do with radios, but I got the
advice to ask here.

I want to be able to record a telephone call and on the same time myself
provide the input signal (rather than talking into the handset). The
reason is that I want to record a telephone call where I also can
process my own voice when speaking, that is, speaking into a microphone,
process the sound and then send it to the phone.

Some device with one audio connector in and one audio connector out
would be perfect, and also of course some connection to the telephone,
maybe to the headset connector.

There are simple and cheap devices where you can tap the conversation
through an ordinary audio connector (less than $20), but I also would
like to provide the input signal through a connector.

I am hoping to find something simple and inexpensive - preferrably less
than $50. I am not into electronics so I won't be able to build anything
myself; I am looking for a product to buy.

Thanks in advance.
