Theres only a few ways to know for sure, a) dial the number see if you get a reject or not lol b) lidb lookup (not always possible) c) look in lerg to see if the NPA-NXX is even valid in the first place, you can also try LNP (and maybe CNAM) lookups to see if you get a valid result there, it is possible to get a CNAM on a disco’d number...

Well, pretty much the only way to guarantee that a number is working is to call it and see what happens. 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.

I would also love to hear from a few of the callcenter guys/gals on the list about this topic.


 
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?

I think it's because it counts as a short-call on the account. The provider has to do all the work of setting up the call and tearing it down without getting any billable minutes for it. Just a guess.



Best,
