AT&T IP Toll Free
1 Introduction
This Guide describes the steps for configuring the Network Equipment Technologies
(NET) Tenor AF, or Tenor AX to work with AT&T’s IP Toll Free Service. The NET
Quintum-Tenor AF/AX provides VoIP capability to Analog Telephones, Analog Key
Systems and Analog PBXs. Tenor Software release P108.09.02 was tested with the
AT&T IP Toll Free Service.
AT&T IP Toll-Free is a managed Voice over IP communication solution that supports
inbound toll-free calling on your data network giving you toll-free service for your U.S.
sites. Toll-Free calls originate in the PSTN (Public Switched Telephone Network) and
are transported over the AT&T MPLS network for delivery via an IP access facility.
The NET Tenor works with your legacy premise telephone equipment and Call Center
applications to answer Toll Free (8YY) calls.
The Tenor AF/AX is a gateway device that converts AT&T IP Toll Free calls to be
answered by your legacy Analog Telephones, Analog Key Systems, Analog PBXs and
Analog Call Center applications. The Tenor AF/X uses SIP signaling to answer calls
from the AT&T IP Toll Free network.
References in this Service Guide to “Tenor” refer to the Tenor AF or Tenor AX.

4 Configuration Component Overview
This section provides an overview of the NET Tenor integration with the AT&T IP Toll
Free Service.
4.1 AT&T IP Toll Free Dial Plan
For IP Toll Free, the AT&T network will send the call to the NET Tenor using the IPTF DNIS (also
known as signaled digits out-pulsed or SDOP) as provided by AT&T Customer Care. Note that
the DNIS will always be pre-pended with 5 leading zeroes (i.e. “00000”).
Other key fields are defined below:
–
Dialed Number Information Service (DNIS)
–
AT&T Private Number (APN; Used for Internal AT&T Toll Free routing)
–
Calling Party Number (CPN)
Parameter Location in SIP Message Example:
DNIS: User part of Request URI
INVITE sip: 000001025@192.6.0.1:5060 SIP/2.0
APN: User part of To header
To: <sip:0004153251025@192.6.0.1;user=phone>
CPN: User part of From header
From: "OUT_OF_AREA"<sip:3178723000@207.242.225.200:5060;user=phone>;
tag=dsa3ca8be7
INVITE sip: 000001025@192.6.0.1:5060 SIP/2.0
To: <sip:0004153251025@192.6.0.1;user=phone>
From: "OUT_OF_AREA"<sip:3178723000@207.242.225.200:5060;user=phone>;

4.3 Tenor AX Overview
The Tenor AX is a high-density VoiP (Voice over Internet Protocol) SIP/H.323 switch
that compresses and packetizes voice, fax, and modem data and transmits it over the IP
network. The Tenor AX gives larger businesses with analog voice infrastructure a means to use
Voice over IP (VoIP).
The Tenor’s MultiPath architecture enables it to intelligently route calls between the
FXS, FXO, and the VoIP network. The Tenor AX also routes calls over IP to reduce
Page 6 of 45
NET - Quintum Tenor Configuration Guide
AT&T IP Toll Free
costs, and then transparently “hop off” to the PSTN, to reach off-net locations. Calls can
be routed in any direction between any of the ports.
The unit’s plug and play embedded system architecture brings VoIP technology to your
network without changing your existing telephony infrastructure. The Customer’s
network stays as is, and the call type is transparent to the user.

4.4 Tenor AF Overview
The Tenor AF is a VoIP (Voice over Internet Protocol) H.323/SIP switch that digitizes voice, fax,
and modem data and transmits it over the IP network. The Tenor AF gives small to medium
sized businesses with analog voice infrastructure a means to use Voice over IP (VoIP).
The Tenor’s MultiPath architecture enables it to intelligently route calls between the
FXS, FXO, and the VoIP network to achieve the best combination of cost and quality.
The Tenor AF also routes calls over IP to reduce costs, and then transparently “hop off”
to the PSTN, to reach off-net locations. Calls can be routed in any direction between any
of the ports.
The Tenor can be installed without upgrades to the existing voice or data network. You
can install the unit in a home or office environment, without affecting the network
infrastructure you already have in place.
