We have setup the asterisk on Ubuntu, we want to develop a application which can broadcast prerecorded message to multiple mobile numbers at the same time.
For ex. User will schedule a campaign for particular date and time, the campaign should start at the specified time and broadcast call (all call will be placed at the same time to all contacts into that campaign).
we have found some commands and techniques but those are for extensions . We are not much familiar with asterisk, so we are not sure how to start this application.
Also we did some googling and got some terms like call file, also there is Zap terms which is not clear to me, and how can we use this settings.
Any suggestion will be much appreciated.
