[Task] Remove ISDN [Status] not started [Responsible] not assigned [Description] 
ISDN has been surpassed by DSL modems and is not being used that often as it was in the past. However, the ISDN mailing list was not removed, so maybe we should discuss whether we still need this section in the handbook.
