It is necessary to call the subscribers to collect information.
The asterisk has a solution for auto-dialing, but the main problem is that when calling from an aster, an answering machine can answer the subscriber or the user can not enter anything or the user can select the item "call back later" and in this case the aster will provide the Completed call system and the regular auto-call system will complete work with the number.
Is it possible to zafalit call status as from a dialplan so that the asterisk calls back by its own means later?
I put the Elastix for the test with the CAll Center module, but it seems to me that dialing can be done there only with the help of live operators ... Or can you still make a calling campaign with robots?
