[cisco-voip] RE: call managers names

[Lelio Fulgenzi]

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 unix 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 internal 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 outside world.

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

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