Check if a phone number is valid and active in asterisk

I would like to know if there is a way to check if a phone number is a real number and active, not a fake number or disconnected number. I would like to import only working numbers into our crm and block phone numbers that look real but do not have a dial tone.

something like ping for phone number with asterisk where I would in a way call the phone without making it ring so I can verify the phone is not disco or bad phone. Is this possible?

Within North America you need to do LNP / LRN query to check if the phone exists or not and also get the termination/outbound costs. Sometimes it's useful if you want to know from which state this number had been generated(even though it's not accurate due to numbers portability )

Here is one of the service provider https://www.alcazarnetworks.com/data_services_lnp_lrn.php

FYI: I'm nor working for this company neither sponsoring them or recommending them. I just used them in the past.

This is possible. You can create a application which will pick/select the number and dial via AMI originate command. You have to capture AMI events and wait for originate command success response, after that status = Ringing. Once it ring send the hangup command on the channel via AMI. Now this number is valid and correct. This would be 85-95% accuracy. Hope you got some idea!! Let me know if you have any questions.

This is not possible. Even the phone companies cannot do it to numbers that are not theirs, so customers certainly can't.
