    Calling a telephone number?


    Is there anyway to verify a user input phone number is real?

    Wikipedia says we can issue some tests

    http://en.wikipedia.org/wiki/Telephone_number_verification

    Code:
    Line test
    
    An aborted call is made to the subscriber line. This automated service “listens” to check for Ringback tones, Busy Signals, Answered call, Voice mail automated answering, or network operator injected messages such as “the number called is not in service”. This method benefits from being international and covering mobile phones. However, the check can take up to 30 seconds to complete (average time 9 seconds). This delay can be handled well by the use of AJAX background processes for example by allowing the user to continue filling in other fields in a form while the line test is performed.
    the bolded text seem to suggest we can do it but i have not been able to get this info from google

    There are 10 kinds of people in the world. Those that understand binary and those that don't.

    Normally you verify a phone just like you would an email address: Send it a special code and have them input the code. That's how google voice does it.

    Thanks. What got my hopes up was the wikipedia reference to doing check in the background through Ajax.

    You need a PoP from the phone company to do line tests, it's not something a computer just does over the internet.
