Stage 1: Need to dial an access Number from a database using
Asterisk+SIP. Once the call is answered by the receiving party ( it
will be answered by an automatic IVR system.) a PIN number has
to be Dialed in( DTMF).
Stage 2: After the PIN number has been verified by the receiving party.
We will either get a dial-tone or a voice prompt to dial a
destination number. This number will be dialed by an outside
system (Softswitch) into the Asterisk. Once the number has been
dialed Asterisk needs to re-transmit it to the receiving party IVR
to establish the call.
