Increased network security is provided in accordance with the invention by using information obtained from the signaling network to determine whether a call has been forwarded, and then using this information to make a determination as to appropriate further call processing, to minimize a communications company's exposure to call forwarding fraud. A determination of whether a call is a forwarded call can be made on the basis of a call forwarding indicator provided by another portion of the communications network. Where such an indicator is unavailable, a determination of whether a call is a forwarded call can be made by comparing the telephone number dialed to originate the call with the telephone number (the 'connect number') associated with the telephone station to which the call has been forwarded. When the dialed number and the connect number differ, the call is determined to be a forwarded call.

Method for processing forwarded telephone calls

When a caller making a collect call encounters a busy called party or one that does not answer after a prescribed time, the telephone network offers the caller the opportunity to store a voice message in a messaging system at no charge to the caller. After the caller stores a message, one or more attempts are made to establish a connection between the messaging system and the called party's telephone. This may be done by periodically alerting the called party's telephone when it is in an on-hook state. When the called party answers, e.g., by going off-hook, the messaging system informs the called party that a collect voice message awaits him and asks if he is willing to pay to receive same. If the called party signals that he is willing to pay to receive the voice message, the messaging system plays the stored voice message from the collect caller and signals the telephone network to charge the account of the called party for supplying the message. If the called party signals that he is unwilling to pay to receive the voice message, the message is not delivered.
