Modem and Virtual serial for wardialing tool?

[fpietrosanti]

We are prototyping a wardialing software that will dial a range of phone numbers like 800-XXXXXX trough a VoIP connection, using G711 wideband 64kbit codec and will look for modem carriers.

That will be opensource software, with no hardware, and we are looking for a DSP component that we can use from Python (also using CFFI c-library interface) in order to be able to:

• pass as input/out PCM-audio-flow
• have the modulation/demodulation of the carrier including detection and handshake
• provide an I/O interface where we can hook a "virtual serial" (there's OpenPTY on Linux to do it)

We where looking at SpanDSP but found this liquid-dsp project that seems modern and self-contained.

Does Liquid-DSP could be used for that purpose? What do you think?

I suppose so, but I don't really know too much about VoIP modems.
