I am working with a Fax server utility and I need to trick Microsoft fax into thinking it has successfully sent a fax once it hits the fax server. The reason for this is that Micorosoft fax thinks it's doing the faxing, but in reality the fax server is doing all of the work and relaying the information back to local laptop or desktop. I need Micorsoft fax to think that the faxes completed once they hit the server.
Anyone have any thoughts on the how to do this?

thanks,
