This read-create DisplayString (1-64 characters) is the unique name identifying a call control profile row, required at creation time and immutable afterward. Admins care because misnaming a profile, or trying to rename it via a SET, will fail since the only way to change the name is to delete and recreate the entry. For example, an admin wanting to rename a profile from 'default-gw' to 'branch-office-gw' would need to create a new entry with the new name and delete the old one rather than modifying this object directly.
