ABSTRACT:
An adjunct processor (16) sends an end-of-address indication, such as a pound sign, along with the address, such as an extension number, to which a call is to be transferred, to a switching system (12, 14). The sent end-of-address indication causes the switching system to not accept further addressing information from the caller (10), thus preventing the caller from modifying the sent address and effecting the transfer of the call to an address different from the sent address, such as a long-distance telephone number. Perpetration of adjunct-assisted toll fraud is prevented thereby.
