I have a list of phone numbers of customers. I would like to check if the phone numbers they field are correct. The only way to do this, is to phone one by one each phone number and listen if the phone number is real. So I need a software which can give just a ring to test the phone number.
Just off the top of my head you could script it to make the calls and then look at the CDR to determine if they were answered. But i would highly recommend having it play some sort of message when answered and/or ask for user input to confirm their number so you dont’ have a lot of calls going out just to hang up on someone.
