In USB-based IP VOIP phones - phones you plug into USB adpaters on your computer - as the phone is plugged into the USB card and not the sound card, do the units have  digital to analog converters built-into them? I can't see how else they would work but I would like to check.

    Yes, they will be built into the chip set like they are on cell phones.

    Yes all they are is basically a combination of a regular USB sound card which is wired directly into the speaker and microphone of the handset.
    Some may rely on the phone software to play the ringing tone through the normal pc speaker or sound card and the call sound through the usb sound card. Alternatively they may be designed for the ringing sound to be sent to the handset aswell and until the answer button is pressed etc... the audio comes out of a separate built in speaker instead of the earpiece (in the same way as a mobile phone does when you put it in speakerphone mode).
