• and
• a voice application server for handling VoIP calls to and from the at least one subscriber telephone number,
• wherein the voice application server is configured to:
• receive call preemption request information from the service provider;
• generate an incoming call policy configured to allow incoming calls to the at least one subscriber telephone number from only the at least one LEA telephone number;
• store the incoming call policy in a memory associated with the voice application server;
• activate the incoming call policy;
• generate an outgoing call transfer policy configured to automatically transfer all outgoing calls from the at least one subscriber telephone number to a designated one of the at least one LEA telephone numbers;
• store the outgoing call transfer policy in the memory associated with the voice application server;

• generate, at a voice application server, an incoming call policy configured to allow incoming calls to the at least one subscriber telephone number from only the at least one LEA telephone number;
• store the incoming call policy in a memory associated with the voice application server;
• activate the incoming call policy;
• generate, at the voice application server, an outgoing call transfer policy configured to automatically transfer all outgoing calls from the at least one subscriber telephone number to a designated one of the at least one LEA telephone numbers;
• store the outgoing call transfer policy in the memory associated with the voice application server;
• and
