Bulk test phone numbers

I have several hundred DID numbers from various carriers that I’d like to test to see if they are even still active or if they have been disconnected. Is there an easy way to bulk “dial” these numbers and get a report of their success?

These are all numbers we’ve owned at one time or another. We’ve collected a list for potential porting to a single carrier but would like to validate the list first.

I was considering writing a modem dial script and then capture the outputs but thought I’d ask the smart guys here first.

Sipsak (or sip vicious :wink: ) come to mind
