Installing and Configuring the Quintum
Tenor AS Gateway
Introduction
The Quintum Tenor AS is a 2-4 port analog gateway used in NetVanta Unified Communications Server
installations to provide a gateway between internal (SIP) phone calls and the outside phone network
(PSTN). Voice communications from an internal phone have voice over IP (VoIP) signals converted into
traditional analog voice, which is transmitted over the PSTN.
A gateway works in conjunction with the UC server’s SIP Proxy and SIP. All telephony services are
provided through the mutual cooperation of SIP gateways, SIP telephones, SIP proxy and the Core
Application Service.
The following diagram illustrates the UC server’s SIP architecture and its relationship with other
components in a typical customer network.

Interoperability Software Versions
The following gateway version was tested for interoperability:
System Description: Quintum Tenor AS
Hardware Version: P106-02-00
Firmware Version: P106-12-00
Overview of Procedure
To provide its functionality, the Quintum Tenor AS must be connected to the internal LAN (a 100 Mbps
connection is recommended) and from 1-4 PSTN analog phone lines.
The Quintum Tenor AS is primarily configured using a java configuration program. The program must
be installed to configure and manage the gateway.
The basic steps for installation and configuration are:
1. Unpack the Quintum Tenor AS.
2. Mount the Quintum Tenor AS.
3. Connect cables.
4. Power up the Quintum Tenor AS.
5. Set a DHCP IP address reservation for the Quintum Tenor AS based on its MAC address.
6. Run the initial configuration wizard.
7. Configure the UC server to use the Quintum Tenor AS.
Note: Please see the instructions provided by Quintum for steps 1 to 4, and for information about running
and configuring the gateway.
The rest of this document provides instructions for steps 5 to 7, which allow you to configure the
Quintum Tenor AS for operation with the UC server.
Address Reservation
By default, the gateway is configured to use an IP address assigned by DHCP. The gateway can also be
configured to use a static IP address. For routing calls out from the UC server, the Quintum Tenor AS
must have an IP address that does not change.

Enabling CNG Tone Detection for Faxing
By default, a Quintum gateway will not detect CNG tones used for faxing unless the call is directed at a
fax service. In order to receive faxes when a call is answered by a standard service (not a fax service), you
must create a file and upload it to the gateway via FTP.
To enable CNG detection
1. Open notepad or another text editor.
2. Put in the following line: enableCNGdetection 1
3. Save the file as var_config.cfg.
4. From your Windows PC select Start > All Programs > Accessories > Command Prompt. The
Command Prompt window is displayed.
5. Use the CD command to change to the directory on your PC in which you saved the
var_config.cfg file.
6. Type ftp followed by the IP address of the unit. Press Enter.
7. Login with the username and password. The default for both is admin.
8. Use the CD command to change to the cfg directory (this is the directory on the Tenor into which
you will copy the var_config.cfg file). Depending upon the product type and software revision,
the directory structure you see in your Tenor VoIP device may be different.
9. Type bin <Enter>.
10. Type put var_config.cfg <Enter>
11. Restart the gateway from the Tenor Configuration Manager in Tools > Reboot Tenor.
Configuring the UC Server
After you add the gateway to your network, the UC server must be configured to handle incoming and
outgoing phone calls. For outgoing calls you must add: a SIP gateway, a dial plan entry to route calls out
through the gateway, and a toll restriction entry to allow those calls. For incoming calls you must add a
UC server identity that can answer incoming calls from the gateway. These instructions are for release 4.1
of the UC server.
Adding a Trunk Identity
1. Go to Identities.
2. Right-click the right panel and select New Identity.
3. In the first page of the Wizard, select an Attendant identity. Make sure that the Identity is
associated with the Admin profile.

4. On the following page, enter a descriptive name and enter 10000 for the address (assuming a
standard configuration). Make sure that Default Trunk Service is the selected service.
Adding a SIP Gateway
1. Select Gateways.
2. Right-click the right panel and select New Gateway.
3. Choose Public Switched Telephone Network (PSTN) from the gateway list.
4. In the Host name field, enter the IP address of the gateway.
5. Enter a descriptive name for the gateway.
6. Save.
Configuring the Dial Plan
Incoming calls from the PSTN are already configured by having incoming calls routed to the 10000
Trunk identity. An entry or entries must be entered in the Dial Plan for outgoing calls to the PSTN.
1. Go to Communication Service > UC Server > Routing.
2. There are many possibilities here. If regular PSTN calls are to be routed out the gateway, add or
modify an entry where the Original Digits are [0-9]{7,} and select the gateway. For example:
