I could be wrong, but I don't think this is possible without answering the channel first (which will charge them for the call).
But hey.. if you figure it out let me know! we've managed to do web callback, ANI/CID callback, and DID callback when dedicated to one user. But "secure" PIN-based callback like you're suggesting is something I'm not sure is possible. Typically a PIN-based callback would call back *anyone* who dials it, and then prompt them to enter their PIN. The good news is this shouldn't be too hard to implement with your software, the bad news is that you have to pay for all of these calls regardless if users authenticate or not - if they don't authenticate then there's no one to bill and you end up paying for the call yourself. That's really the only reason we haven't done PIN-based callback so far. There's nothing preventing someone from causing you a good bit of financial damage by repeatedly calling the access number with fake CID in say, Cuba. --- On Tue, 5/13/08, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > From: [EMAIL PROTECTED] <[EMAIL PROTECTED]> > Subject: Re: [asterisk-biz] DID to Pass CLI > To: [EMAIL PROTECTED], "Commercial and Business-Oriented Asterisk Discussion" > <[email protected]> > Date: Tuesday, May 13, 2008, 1:12 PM > Mr Nitzan, > > Its good to know that its possibe, My requirement is to > facilitate > customers to dial DID number followed by PIN, so that they > will be > authenticated and get the callback.
