I have searched around and as of yet have not found what I am looking for.
I have a list of say 1000 numbers that I need to confirm are working phone numbers. I understand that you can do a line test that make an abandoned call, this call checks for a response from the other end and is able to determine if the line is active or inactive.
The procedure obvsiouly exists but I am unable to see how this could be implemented with asterisk. I would imagine that such a tool or script already exists. Can someone let me know where this tool can be found or point me in the right direction of how this can be achieved. I have experience with coding so will not have trouble creating this if I know the basic info on how to achieve this. I have used AMI briefly and wonder if this is the way to go.
any help is appreciated.
