The best way is to take a packet capture and see if the requests from the provider are actually arriving; then you will know at least whether they are reaching the server, and from there can see why they may not be getting handled properly at the application level. If the number worked before, and spontaneously stopped working, and you did not change any configuration, it is most likely the provider. -- Alex Balashov - Principal Evariste Systems LLC 1170 Peachtree Street 12th Floor, Suite 1200 Atlanta, GA 30309 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/
