Some quick testing notes: while you do need to do a full OpenSRF / Evergreen install in order to test this, you don't need to worry about setting up Apache / websocketd / Nginx or having a TLS certificate or anything like that. You can practically test with just ps or top, though using srfsh to perform a request and also logging into SIP with netcat / nc / telnet / whatever would be more thorough.
