To prevent fraudsters from illicitly collecting the authorization number or authorization code, as well as personal identification number, of an unsuspecting authorized user of a public pay phone, the instant invention disables the keypad of the telephone so long as the pay phone is connected to an incoming call, unbeknownst to the authorized user who is attempting to dial out from that pay phone, and the user is detected to have lifted the handset of the pay phone to attempt to dial out. An alternative method of ensuring that the authorization code of an unsuspecting user is not misappropriated includes adding a circuit to the circuitry of the telephone to ensure that a true dial tone is provided when the user picks up the handset. If no true dial tone is detected, the keypad of the telephone remains disabled. The first and second embodiments may be combined to form yet another circuit that could be added to a conventional pay phone circuitry to prevent pay phone credit/debit calling card authorization code fraud.

To prevent fraud perpetrators from using a public pay telephone to illicitly collect account numbers, authorization codes or personal identification numbers from an unsuspecting user of the telephone, the instant invention disables the keypad of the telephone if an incoming call is being received at the time that the handset is lifted from the phone by the user. In one method, the ringing signal and the off-hook condition are detected and a control output is provided which disengages the dialing tone generating circuits of the telephone until the handset is placed back on-hook. According to an alternative method, after the handset is lifted, a dial tone is sensed and evaluated by a dial tone discriminator to determine whether the dial tone is likely to be a valid dial tone from a legitimate service provider. If the dial tone is determined to be invalid, then the keypad of the telephone is disabled until the handset is placed back on-hook.

A telephone system and method is provided for delaying authorization validation queries until after a called party accepts a telephone call. Queries are avoided not only in cases where the called phone line is busy or not answering, but also in cases where the called party declines to accept the charges. Because authorization validation queries typically take less than half a second, parties are not significantly affected by the delay.

Fraud prevention in a telecommunications network using call initiation equipment including intelligence capable of authentication is described. In order to initiate a call via a telecommunications network, the call initiation equipment sends authentication data to an adjunct platform. The adjunct platform uses the authentication data to determine if the call initiation equipment is authorized to use the customer wireline that interconnects the call initiation equipment to the telecommunications network.

A telephone system and method is provided for delaying authorization validation queries until a dialed phone is answered. This way, authorization validation queries are avoided in cases where a requested phone line is busy or not answered. In a collect call scheme the system may even delay queries until a party agrees to accept the collect call billing charges. This way, query charges are avoided not only for busy signals and no-answers, but also in the event that the requested party declines to accept the charges. Because authorization validation queries typically take less than one half of a second, parties are not significantly affected by the delay.
