[cisco-voip] Conversion from Centrex to VoIP

I asked this question before but did not get a response from anyone.  I 
am going to reword it...

We are in the process of switching from Centrex to VoIP.  As we move 
along and convert each department, we find timing difficult because as 
soon as the phones are entered in Call Manager, those already on VoIP 
calling the lines on that phone get an error since the phone is not yet 
plugged in.

In addition to having convert the lines from Centrex to our DID block (I 
can work around that), we find it difficult to come up with a solution 
with being able to work ahead of schedule by adding the phones into Call 
Manager without having calling issues from VoIP phones. 

Anyone know of a creative way to add these phones to Call Manager but 
isolate them from other VoIP phones until we are ready to deploy them to 
desks? 

Thanks,

Lisa
