Any way to ping a phone number?

Question

We have a client who wants to go through their CRM database and somehow determine the phone numbers that really, without the actual presence of someone there, and try to call them all.

Is there a way to do something similar to ping a phone number (including landlines)?

Answer 1

You will need to go through a third party. I used Melissa's data to verify the address with good success, they also offer phone verification, but I did not use it

It was based on a module called app_amd.c (Answering Machine Detection), which was a third-party add-on for Asterisk and AFAIK, now can be found in their main tree. With E1 / T1, you can also distinguish between bad numbers, busy numbers and many other status codes. See how this can help.
