I am sorry for the very simplistic question;
I would like to set-up a service that does the following:
A - A user dials to a number with in the PSTN, where the Asterisk server is connected to (E1/ISDN30);
B - An auto attendant feature on the server answers the call and plays a pre-recorded message;
C – During or After the message is played the user gets a dial tone;
D – The user dials any number and gets connected to that number;
E - Billing starts from the moment the auto attendant answered the call till when the user ends the call.
1 - Is it possible to configure Asterisk to work in such way (Points A,B,C & D)? Is there a name for this set-up/feature?
2 - Is there a billing engine or an accounting package with in Asterisk (Point E)?
