New G4 - Speakerphone software?

[KathyMac!]

Hi all,

I have just purchased a new G4 Tower (DP 1ghz) from SmallDog.com. It's not
here yet but I'm getting ready for it. I currently run a Beige G3 Tower (300
mhz) and I utilize an old Cyberphone modem for a speakerphone/telephone
system.

Since it runs by serial port I'm wondering how I will be able to use my G4
as a phone.

Any ideas? Is there speakerphone software out there? I know there used to be
Megaphone but that's been discontinued, correct?

Does anyone use their Mac as a phone?
