(a) associating a personal identification number with a directory number at the IP phone switch;

(b) establishing communications between the IP phone and the IP phone switch;

(c) receiving the address code of the IP phone and the personal identification number from the IP phone;

(d) authenticating the personal identification number;

(e) associating the directory number with the address code for routing and switching call traffic to and from the IP phone,

(f) wherein step (c) is repeated in the event that the personal identification number fails authentication in step (d); and

a database having personal identification numbers associated directory numbers;

a communications system for establishing communications between IP phones and the IP phone switch; and

an QAM for associating directory number with address codes of IP phones for routing and switching call traffic to and from the IP phones;

wherein, after communications is established between an IP phone and the IP phone switch, an address code and a personal identification number is sent from the IP phone to the IP phone switch for registration of the IP phone, the address code and personal identification number is received by the communication system and passed to the OAM where the OAM authenticates the personal identification number with the personal identification numbers in the database and then associates the directory number with the address code of IP phone for routing and switching call traffic to and from the IP phone.
