If a public telephone is being used for prostitution, drug dealing, or any other illegal purpose, it is a problem telephone.
Upon notification of the existence of a problem phone, the DSI will hold informal hearings to gather evidence and take testimony as to the validity of the claim.
Upon confirming that a particular telephone is a problem phone, the DSI may issue an order to the licensee and the owner of the phone to either restrict usage or have the phone temporarily or permanently removed.
