    i was wondering how dose VoIP CallBack work?

    example:

    1- a user in China call a number in the US. after the first ring the user hang up.

    2- the CallBack server calls the user phone, and ask him to enter his PIN, then ask for the dist. number and connect the call

    is it possible to restricate the callingback to a specific phone numbers?

    is there an “antiflood” system to prevent some ppl from keep calling and calling the callback number?

    thanks

    There is a high chance that his ANI will not be detected by the server in USA. E.g. US gateway will receive something like 04532324, which is a local number in the area customer is China – but there is no way to tell which province it is in.

    Of course, it is all up to the callback server – how you will set it up.

    See above.
