[cisco-voip] RE: call managers names

[Kevin Thorngren]

Here is one of the issues you might run into with using an underscore  
for the CCM name:
http://www.cisco.com/en/US/products/sw/voicesw/ps556/ 
products_tech_note09186a008010f70b.shtml

There are a few others I have seen; Voicemail port wizard failing and  
problems with updating Gateway information.  Of course when these  
problems occur there is a TAC case that is created and it usually takes  
a awhile for us to notice the URL has an underscore.  Most of the  
problems can be worked around by using the IP Address instead of the  
hostname in the URL.  Also, an underscore is not supported by Cisco  
TAC.
