Yes, you will if you use these names in DNS too.

Yes you will.  You should use valid DNS names for hostnames of CM
servers.  This means no special characters and it has to start with a
letter.

underscore was not a valid character in the original dns rfc.  you
will get mixed interoperability. safest option is to not use underscore.

interestingly enough, the underscore is heavily used in the active directory
 world. we made a conscious decision in our DNS team to allow these, because
, well, without it, some active directory applications wouldn't work. our un
ix guru did some research and basically, as wes mentioned, strictly speaking
 it's not supported, but people have moved towards it. so as long as your in
ternal DNS servers support it, then you should be ok. i think the danger is 
when you try to create dns entries with underscores that will hit the outsid
e world.

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.
