[cisco-voip] Easiest way to change the operator in Unity

[Voll, Scott]

I have just brought a new site on with CM 4.1.3 and Unity 4.0.5 (UM).  I
have imported all the users in from Exchange (AD 2003, exchange 2003).
What is the easiest way to change the 0 in all these accounts to point
to the operator at the new site?  

TIA

Scott
