Hostnames for Prophecy and VoiceObjects

Symptoms

Will VO have an issue if the hostname of the machine in RHEL Linux has '-' (dashes) in it? We were unable to get it to start when the hostname had an underscore '_' in it.

Prophecy and VoiceObjects do not work correctly when the computer hostname contains an underscore.
Do they work when the server name contains a dash?

Cause

Java does not allow an underscore in host names of machines running VoiceObjects or Prophecy.
The Java online help states the following: Allowable characters in a label for a host name are only ASCII letters, digits, and the '-' character

Resolution

Use a hostname with only allowed characters like described in the Cause.
