3.8 Voice CallBack Centre Configuration
The Voice CallBack Centre (VCC) adds new features to the standard CallBack function
of the gateway. With the VCC you can increase the count of users and add CallBack
time limitations to each user. This software is an optional part of the system. For
additional information please contact your dealer.
Function Scheme

an unanswered call is hung up.
2) The gateway sends the user authorisation request to the VCC.
3) The VCC authorises the calling party.
4) The gateway starts calling back to the calling party and waits for call
connection.
5) The calling party receives a voice message for DTMF dial-in and the dial
destination (called party number).
6) The gateway sends the destination authorisation request.
