Hello:
I have a conventinal external serial line data/vioce/fax modem. Is it possible to make phone calls through the computer using this modem?
No, it isn't possible. The next obvious choice is VoIP, but a 56K modem is not enough.
Well, probably I haven't made it clear. I don't want to use the modem to connect to the internet and make conversation through the net. I want to make conventional telephone call but instead of the handset (speaker and microphone) of the telephone I'd like to use my headset connected to the computer and use the modem to forward/receive the call (ie replace my telephone by modem+computer-headset).
My moden have two 3.5 jack type plugins labeled as mic and speaker.
I will check hylafax as Carlos suggested.
Thanks, and if you have any concrete idea, please let me know.

You can do that, but with only 56K (actually, 56K down, 33.6 up) you'll have to use compression. The tightest compression is G.729A at 8 Kb/s, plus overhead. You may be able to get by with less compression and still fit within that modem's bandwidth.
I do not understand why I should use compression. The regular phone conversation is not compressed either. Once more, I don't talk about VOIP. The issue is how I can transfer voice from the computer to the phone line with the help of the modem.
