This is a project I desperately needed a few times in the past, but could not find anything covering my needs.

What it does is to act as a SIP softphone, and spawn a process for each incoming or outgoing call, which can handle events (like DTMF tones) or do actions (like playing files) via stdin/stdout.

Currently, I am using it to spam filter incoming calls at home.

As a side question: I wonder where one can publish software like this nowadays, when freshmeat etc. are either gone or read-only. Preferably a place that is not GitHub.
