Chapter 1: Overview 1-7
Call Detail Recording
Through the Call Detail Record (CDR) feature, the Tenor BX generates a call record at the comple-
tion of each call, typically for accounting purposes. A CDR is a string of data that contains call
information such as call date and time, call duration, calling party, and called party.
Tenor BX may
store Call Detail Records locally or they can be sent to a CDR server within the network. The CDR
contains sufficient information to capture billing data, which can be used to create billing reports
using third party billing software.
IVR/RADIUS Support
Interactive Voice Response (IVR) is a feature of the Tenor BX that enables you to offer services,
such as Pre-paid calling cards and Post-paid accounts, to your customers.
The Tenor uses the RADIUS (Remote Authentication Dial-In User Service), for authenticating and
authorizing user access to the VoIP network, including ANI Authentication (Types 1 and 2). The
RADIUS is a standard protocol which provides a series of standardized message formats for trans-
mitting and receiving dialed information, account data and authorization codes between the network
access gateway and the billing server.
NAT Access™
NAT Access is an intelligent network address translation technology. It enables VoIP networks with
multiple H.323 endpoints to operate behind firewalls equipped with H.323 Network Address Trans-
lation (NAT); this provides maximum network security. NAT
Access simplifies deployment by elim-
inating the need to place the Tenor on a public IP network. Using NAT Access provides easy, secure
expansion between multiple VoIP sites. In addition, NAT technology in the Tenor permits the use of
private subnets at the same time; in-house calls will never go over the public internet.

Routing Table Options
There are four types of routing databases you can configure: Bypass Directory Numbers (BPN),
Hunt Local Directory Numbers (Hunt LDN), Hop-Off Directory Numbers (HDN) and Static Routes.
Bypass Directory Numbers. Bypass Directory Numbers (BDN) are telephone numbers that are
automatically routed directly from a line circuit to a trunk circuit (PSTN); they will not be routed
VoIP. Some examples of bypass numbers include toll-free calls, emergency calls (i.e., 911), or high
security calls.
