It looks like VNC is causing the problem.
I just installed VNC server on my test rig and got the same error after connecting to the Pi before starting SIP from the command line.
A couple of solutions:
1. If you are on Windows you can use putty to access the Pi command line headless.
2. set up SIP to start automatically at boot as described in the SIP documentation wiki:
https://github.com/Dan-in-CA/SIP/wiki/Installation
Then after a reboot you should be able to access SIP's web UI from a browser.
It looks like you will still be able to connect with VNC when SIP is already running.
