V.34 Question #77

Open YeeYoungHan opened 3 months ago

YeeYoungHan commented 3 months ago

Can I send or receive a fax using V.34 with spandsp 3.0.0?

I think there are source code fragments related to V.34... I'm not sure where the source code is for starting fax transmission or reception with V.34.

I have tested the current code. I made a call and response with the fax machine using V8, and both sides exchanged information normally. However, when attempting to establish a connection using the V34 half-duplex modem, it was unsuccessful.
