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 DX asks if the caller wants
another call; the user can then press the designated key. Pre-paid and Post-paid Calling Card - Call Flow
(multi-session support) 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 DX 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.
