It could very well be that somebody migrated all the relvant phone numbers off the test system, and chose to preserve those numbers where they didn't know what they were needed for. Might be cheaper than risking losing functionality that somebody depends on. (Especially if the one doing the migration didn't know it was an abandoned test system).
12 years later, the phone number still is working, even though the companies phone system has been relocated to another room and was replaced by another vendor. No idea how this happened.
