    Phones not registering

      Hi,

       

      I've got a collaboration 10.5 lab booked for the next few days, but no matter what i try my phones won't register.  The messages i'm getting are

       

      DNS unknown IPv4 hot hq-cucm-pub.

      VPN not configured.

       

      I've enabled auto registration which usually gets things going but not this time.


      Any ideas.
