[cisco-voip] CM6.0 Registration issues

[Lemon]

Hi guys,

I have CallManager 6.0 installed with about 40x 7941 phones registered
to it all working fine. Today we started rolling out more phones (
about 15 x 7941) and suddenly we get the following error when trying
to auto-register the phones:

Registration rejected - Error DBCo

We do have more tha enought license files, and our Auto-Reg number
range is about 400 numbers.

Any ideas?

Thnx

Charl
