> I wrote the system in two parts, the dialer and the user screen. The dialer monitored the ports for activity. When atleast one was free and a user was logged in (App in memory), the system would dial the next available number and keep going until it got a connect. Once that happens, the dialer would populate a record in a table. The user app would detect the existance of a value in a specific record, seek based on that and populate the a form and display it. When the form poped up, the user would pickup the line and begin talking.

Thank you very much for the info. I will look into to building an app using VFP. One question? Did this app require any additional hardware?
