    Hi guys

    I am looking for a speaker phone IC, has anyone used/come cross one? I googled it, it doesn't seem to have a lot in the market.

    Thanks guys!

    edit: or a voice switch IC?
    edit2: ideally not for telephone line, or can have 4 wires(two for signal in, and two for signal out) inputs and 4 wires output. (mic and speaker)
    edit3: or how to use one for phone line but convert the two wires to 4 wires

    Look at the MC34018; I have used it several times.
