VVX 400 Refusing Multi Line Registration

[jmh_ije]

I am trying to setup multiple line registrations on my Poly VVX 400. I can get a single line to register and work correctly, however when I add the second registration, the phone refuses to register with the PBX entirely.  I believe that I have the configuration in the phone correct.

EDIT: The phone has magically decided to try and register. Though my issue is now resolved, I would still like to know what might cause this...

This is important especially in the future when someone finds this post in days, months, or years to come. Please do not simply edit the original post but reply with the versions.

We ar also missing what steps you have tried and more importantly what SIP server is being used.
