Kamailio built on Raspberry Pi
Run a secure VoIP service for $35
I got the stable source tree of Kamailio to build on an RPi with TLS and proxy support. The clean source tree built as documented after adding "DEPS="-DNOSMP"" option to the shell running the compiler.
I don't have database support yet. I encountered a difference between the behavior of the application source and that source's documentation regarding registration and databases. Ideally, I would like to have an "anonymous" database that would be destroyed on reboot. This is supposed to be the default behavior of Kamailio but I cannot add users without defining a database URL :(
