Recommendation of modem to use with Powerbooko

[Łukasz Studziński <lstudzin@bacon.umcs.lublin.pl>]

Hello,

I need a recommendation of an external modem to use with Powerbook G4. I
would like it to act as an answer-machine (record voice messages and
faxes when the computer is disconnected). Linux compatibility is a must.

Best regards,
