I am hosting a large conference call at my house this weekend (fantasy baseball draft), and we always have a difficult time hearing the speaker-phone because of the size and number of people in the room.  Is there any way to output the audio from a phone to my Yamaha RX-V2500, so that I could play the phone call over my surround system?  Does anyone know of a reasonably priced phone that has this capability?  Thanks in advance.
