[Freeswitch-users] Determine if a number is valid/working

Hey MC.  I like Steven's response as well.  Can't quite do the connect to
sales agent yet in the process, need to pull credit report and load DBMS


The cost number is cost of lead from providers like google, msn, etc.  It is
a VERY competitive market.  That does not count the cost of sales reps
dialing non-working numbers on about 1/3 of the leads.


I suspect we will offer a tiered approach like:

1.   Area Code, "State" Field and IP Geo Data State Field all match - accept

2.   Else try LNP Lookup for match

3.   Else still fishy - Web Popup to explain and then Robo Dial and require
a "pin" to be entered.

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.

I agree with Steven's assessment (elsewhere in this thread).


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. 

How is that cost calculated and to whom does the money go? Maybe the
"verification call" needs to take place at the time that the form is filled


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.
