METHOD AND APPARATUS IN GATEWAY FOR TRANSFERRING SWITCHED DIALED DIGITS TO SWITCHED PARTY GATEWAY

摘要

The present invention discloses a method and apparatus in a gateway for transferring switched dialed digits to a switched party gateway, wherein the method includes: A. judging whether switched dialed digits from a user match against a table of overlap dialed numbers; B. if the switched dialed digits match against the table of overlap dialed numbers, then transmitting the switched dialed digits in match to the switched party gateway; and C. if a subsequent switched dialed digit from the user is received, then transmitting the subsequent switched dialed digit to the switched party gateway. With this method, the gateway can enforce an open dialing policy through overlap dialing with computability with an existing in-dialog call setting-up flow.
