First Claim
1. A method for resolving a shared secret on a data network telephony system, the data network telephony system comprising a plurality of Portable Information Devices (PIDs) coupled to data network telephones within the data network telephony system, the method comprising in combination:
- transmitting a suggested shared secret to one or more PIDSs from a first PID;
receiving the suggested shared secret on the one or more PIDs;
rejecting the suggested shared secret by at least one of the one or more PIDs and suggesting an alternative shared secret by the first PID prior to accepting the suggested shared secret at each of the one or more PIDs; and
