I have an older modem, but it supports voice and is full duplex. Now this modem uses a Communications and Networking Riser on the motherboard.
Per the wiki these modem natively support AC97 signals.
When querying the modem with
AT+FCLASS=? I get this in return: 0,1,8
Now my question is can I use this modem as an FSX card and then trunk my phone line over voip?
One thing to point out is that this modem does support FUll-Duplex without any gimmicks like routing the voice through the sound card.
Any thoughts would be much appreciated.
