I have a large database of contacts, but many of the phone numbers are disconnected/ out of service. I would like to be able to run an auto-dialer program on a computer with a modem (NOT VOIP, just dial out from a modem) that would just dial the list of numbers just to detect if it gets an out-of-service message or if the call goes through and is a good number. I've done a ton of searching around already, but every auto-dialer program I've encountered is a fancy expensive system that plays automated messages and routes calls to live telemarketers, etc. All I want is a simple program that checks if a phone number is good or if it's a disconnected number, and let me know in the results log, and I don't want to pay an outlandish amount of money for something designed for professional telemarketing companies that does a lot more and is much more difficult to set up. Is there anything out there for my purposes?
Light bulbs you shouldn't buy
There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
