Re: [linux-audio-user] voicemail?

While we're on the subject of voice applications: I'd like to use the PC as a phone, i.e. transmit sound from the mic-in on the soundcard to the phone line, have the sound received from the phone line available for mixing in the sound card's headphone out and be able to dial from software. All this, of course, under Linux. Does anyone know what hardware I should look for for this. I am assuming some kind of modem or modem card but these seem a bit of a minefield. Does the little link cable that runs from a PCI modem card to the sound card do everything I need or do I need to be able to copy data digitally? How can I tell which modem chipsets have enough support to be able to do what I want? TiA, Steve.
