D-Modem was created by Aon's Cyber Labs in 2021, who published it with the article Introducing D-Modem: A Software SIP Modem. This project grew from their idea and their code: slmodemd's audio on a socket, and their d-modem program, a SIP user agent beside it. Their code has since been replaced; the SIP user agent, frontend/dmodemd/sip.cpp, was written anew from a specification of what it does. The modem daemon began as Smart Link's slmodemd (from Debian's sl-modem-daemon package); its code has been replaced too, written anew from specifications of what it does. SIP is handled by libre.
