Pre-paid and Post-paid Calling Card - Call Flow (with Multi-Session Call support)
For a multi-session call, the calling party can interrupt the call by pressing a multi-session key at
anytime and making a new call. When the called party disconnects the call first, the Tenor AS asks if
the caller wants another call; the user can then press the designated key. Figure 6-6 is a diagram of
the call flow for pre-paid and post-paid call card service (with multi-session support), which details
the messages transmitted between the following components:
Calling Party. The originating caller using a pre-paid calling card.
Tenor. The Tenor AS performing the IVR functions.
RADIUS Server. Remote Authentication Dial-In User Service for authenticating and authorizing
user access to the VoIP network. The RADIUS provides a series of standardized messages formats
for transmitting and receiving dialed information, account data and authorization codes between the
network access gateway and the billing server.
Called Party 1. The first destination called party.
Called Party 2. The second destination called party.
