I want to know after dialing a specific number "ATD+XX1233457890" how can I know the receipent have answered? There is no any result code when the reciepent has answered? Because I want to play a voice message when he answered my call.
Many participants here - including myself - hate so much robot calling / bugging / harassing people that you’ll likely find very little help
May be you can clarify intent?
(And even then - not sure I want too much details out there, we have enough of those nuisance in our life already)
