congratulations.
The main goal of the project is to have a fully working software-only VoIP-Modem that can be used for wardialing, dialing a favorite BBS running on Landline number and more.
This is pretty much what I had in mind, too - although not specifically for wardialing, but simply for any use case.
The design is a bit "creative" but it's done a way to make the "Software DSP" issue pluggable and remote (now Asterisk-Softmodem connected to a local asterisk).
As you can see at http://osmocom.org/projects/linmodem/issues I had the plan to do this based on the linmodem code from Fabrice Bellard (who needs no introduction). The code implements more different modems/standards than the asterisk code, and it's not really tied to the winmodem hardware - it simply consumes and produces 16bit samples, so all that's needed to attach it to RTP is to do the aLaw/uLaw table lookup.
But hey, my approach is still vapourware and yours is implemented, so who am I to make suggestions.
Happy hacking, Harald
