Abstract

A method of completing an international call comprises the steps of determining if the international call cannot be completed as dialed for one reason or another and then automatically attempting the call again. There are many reasons for an international call failure including called station busy, domestic or foreign network congestion and invalid dialed number format. The domestic toll network can receive unsuccessful call reason information from either the domestic or foreign network upon the event of an international call failure. It has been shown that if the reasons are, for example, station busy or network congestion, then there is a significant probability that, if the call is immediately reattempted, the call may be completed on the second try. On the other hand, if the reason is an invalid dialed number format, an automatic reattempt of the international called party is inhibited. Also, if the reattempt of a valid number fails and depending on the reason, further international redial services may be offered to the caller.
