Hi,

I think you count with several tools to "clean-up" the calling list. You could use call progress detection to detect if the number is active. Also, you could use answer machine detection to verify if a real person is at the other end. Even you could use ASR and TTS in a script to get some interaction from the called person. However, you could never get sorted all cases, for example, the number could be a good one but belong to another person or it belong to the main number of a company.

FS give some tools. I quite sure you can do some tone detection (busy, no answer, sit, reorder, disconnect, etc) , take a look at:

About answer machine detection, I not sure how good is FS. Take a look to:

You could combine a third party tool to make the work, check this link

I hope this helps you

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.

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?

HI All,

 

My web site customer’s call center claims that 1/3 of their web leads have nonworking phone numbers.  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?

 

Thanks,

Sean
