Thank you for your responses, everyone. MC: This customer has rejected the idea of calling with a message as bad marketing!! In my experience marketing people have their own "logic rules" and I can never follow their thinking. And yes, they have 30 customer sales reps calling these "leads" all day long. They claim 1/3 of the leads have invalid phone numbers. My customer suspects fraud and that someone is submitting false leads to boost their lead rate and fees. Ken: I am not sure we have any language in common - lol. Where can I learn what "ASR and ACD" are? I looked up lidb and lnp already! Also, the cost of a call compared to the cost of a fraudulent lead (over $20) is insignificant. The ideas I have suggested to my customer, for what it is worth, are comparing the State (we are in US) for the IP address of the submitter, to the State on the form and the State of the area code on the form. In the situations where they do not agree, prompt the user for permission to robo call for verification.

I suspect Ken Rice has some experience in this area and I'd definitely like to hear it. If anyone else has thoughts I'd like to hear them as well. -MC P.S. - Why does the customer think that calling the number and playing a short message will take too long? Also, what is the customer's primary concern about the web leads having non-working numbers? Is it because they have humans manually dialing them and it's a waste of time when the person comes across a bad number?

Short of calling it, is there any way with FS (or even a paid service) to determine if a given phone number is a working number? I would like to make an Ajax SOAP call to a PHP page that checks (or dials) the number and returns a status for the validity of the phone number. I have an LUA script that will call, play a short message and hang up, but the customer thinks that may take too long. Any ideas?
