Scope

This document covers the configuration of the Tenor AS/AX/AF/BX/DX/CMS Gateway products.
This quick-start guide enables you to configure a single phone call on a Tenor using SIP.
As a test, you can send the SIP call through a publicly available Proxy Server maintained by Quintum Technologies.

Introduction

SIP (Session Initiation Protocol) offers a new level of mobility for IP calls, as well as integration of call-related services.
Routing in SIP is accomplished by using two servers: Proxy and Registrar.
Because in most cases you will point to the same box and configure the same IP address for both servers, the Quintum Tenor combines the two.

The Proxy Server maintains a table of IP addresses and their corresponding Directory Numbers.
This table is used by the Proxy to find the right place to send your call.
When you dial a number, the Proxy looks up and finds out where the call must be sent.
That information is used to route the call for you.

Prerequisites

• The Tenor's system software must be version P103-08-00 or later (which includes SIP).
  To find out the version number, Telnet into the unit and type show –v.
• Ensure you have your Tenor ready for connection, located on a LAN that is connected to the Internet.
• For the purposes of this quick start, your connection to the Internet is assumed to be through a DSL or cable connection.
  Other gateway connections are possible; use the principles in this document as a guideline for configuration.

Connect Hardware

Your Tenor needs to be connected to your LAN.
If you have already set it up, you can jump to the next section, Configure the Tenor.
Otherwise, you will need to achieve a few basic steps.

1. Assign the Tenor an IP address.
   Connect the Tenor directly to the PC with the supplied serial cable.
   Power up the Tenor and open a HyperTerminal session (or use another terminal emulation program).
   Assign the Tenor an available IP address on your LAN.
2. Make the Tenor IP address publicly available.
   When you connect the Tenor to your LAN (using the supplied Ethernet cable), you should list the Tenor in the DMZ of your gateway router.
   This allows your Tenor to have a publicly accessible IP.

Caution: The gateway router serves as a firewall to protect your LAN from malicious intrusion.
Place the IP address of the Tenor in the DMZ so that callers may access your Tenor, even though it is "behind" a firewall.
Please change the Tenor's administration password as soon as possible to prevent malicious intrusion.

1. Determine the WAN IP.
   When you are configuring the gateway router, use its software to find out the WAN IP that the router has received from your ISP.

Once the Tenor is connected to your LAN, you can configure the unit using Tenor Configuration Manager, and make a SIP call.

Configure the Tenor

Note: The instructions below include information for making a test SIP call using a Proxy Server maintained by Quintum Technologies.
You can hear a Quintum recording as a test of the first call.

1. Launch Tenor Configuration Manager, and when prompted, enter the IP address that you assigned to your Tenor.

Systemwide Configuration

1. From the main menu tree, select System-Wide Configuration > Dial Plan > General tab.
2. In the Country Code field, enter the dial code for the country where the Tenor is located, and in the Area Code field, enter the area code for the DN from which you are calling.
3. Adjust the Minimum and Maximum Dial Digit Length, as required.
4. Change Long Distance and International Prefix for local dialing rules, as required.
5. Click Confirm/OK.
6. From the top menu bar, select File > Submit to submit the changes.

VoIP Configuration

1. From the main menu tree, select VoIP Configuration > Gateway.
   In the Outgoing IP Routing field, click on the SIP only radio button.
   Click Confirm/OK.
2. From the main menu tree, select VoIP Configuration > SIP Signaling Group-1.
   On the General tab, change the Register Expiry Time to 30.
   In the Primary SIP Server field, enter the IP address 12.176.187.191.
   Click Confirm/OK.
3. On the User Agent tab, click Add to display the Add User Agent dialog.
   Enter your full international format phone number in the Primary User field (such as 17324609000), and enter an alternative number in the Contacts[1] field.
   Click OK on the dialog, then click Confirm/OK at the bottom of the window.
   From the top menu bar, select File > Submit to submit the changes.

Circuit Configuration

1. From the main menu tree, select Circuit Configuration > Line Routing Configuration > Hunt LDN Directories > Hunt LDN Directory-pub1.
   Click Add to display the Add Hunt LDN Number dialog.
   Enter your phone number without area code (for example, 5551000) in the Number Pattern field.
   Click OK, then click Confirm/OK at the bottom of the Hunt LDN Directory-pub1 window.
   From the top menu bar, select File > Submit to submit the changes.
2. Select Circuit Configuration > Line Routing Configuration > Line Circuit Routing Groups > Line Circuit Routing Group-phone.
   On the General tab, in the SIP User Agent field, select the User Agent that you defined previously from the drop-down box.
   Click Confirm/OK at the bottom of the window.
   From the top menu bar, select File > Submit to submit the changes.

Phone (FXS)/Line (FXO) Configuration

1. From the main menu tree, select Phone (FXS)/Line (FXO) Configuration.
   Under Analog Online Setting for Phone-Line/FXS-FXO Pair, enable Phone-Line 1 and enable Phone-Line 2, if required, by checking the checkboxes.
   Click Confirm/OK at the bottom of the window.
2. From the top menu bar, select File > Submit to submit the changes.

Give the Proxy's Registrar a minute or two to store the registration information.

Make First SIP Call

Dial the first call using Quintum's DN for test purposes: 17324609000.
The call is then sent to our test Tenor.
After a few rings, an answering machine picks up the call, your call is completed, and you should hear the greeting played back to you.
