Abstract: This invention relates to a method and apparatus for blocking spam messages originated in a different network. An anti-spam check is made in response to an initial Send Routing Information (SRI) (20) message received in a destination network of a message. The result of this check is sent back to the originating network along with a destination address (61) of a switch in the destination network, and SRI spam code (64) and Mobile Terminated (MT) Routing Address Correlation ID (63). If SRI spam code (64) indicates a spam, then subsequent transmission of the MT message (70) with the same Correlation ID (73) is blocked in the interworking switch (5) or SMSC (7).
