CSG SIP Communications Gateway

Overview

The CSG SIP Communications Gateway is a stand alone Private Branch Exchange (PBX). It is suitable for the desktop, or mounting in a typical network closet or restricted access location. The CSG is ideal for small office environments or as an extension to a central CSG PBX.
The CSG can function not only as a PBX, but also as VoIP ATA, or VoIP gateway. It has eight analog ports that can be configured (via modules) as Foreign Exchange Office (FXO) or Foreign Exchange Station (FXS) ports.
The CSG enables you to transform an intercom-enabled Modero Touch Panel into a full-featured IP phone. With the CSG and an intercom-enabled Modero Touch Panel you can make and receive local, long distance, and international phone calls, and have access to phone features like call waiting, caller ID, call forwarding, call queuing, and voice mail.
The CSG comes in three different models: the CSG-500, CSG-544, and CSG-580. The CSG-500 supports up to 50 users, but offers no analog lines. In addition to supporting up to 50 users, you can integrate the CSG-544 and CSG-580 to outside PSTN or POTS networks. The CSG-544 allows for up to four phones and four PSTN lines. The CSG-580 allows for up to eight PSTN lines. The CSG supports AMX Session Initiated Protocol (SIP)-enabled touch panels—such as the MVP-8400i, MVP-5200i, NXD-1000Vi, NXD-700Vi, and NXD-500i—and the MET-ECOM Metreau Entry Communcator, as well as 3rd party IP phones.
In a typical network, the CSG acts as proxy server, registrar, and gateway. A SIP-enabled touch panel acts as a user agent, which allows the touch panel to act as an IP phone. FIG. 1 displays a high-level diagram of the recommended network infrastructure for using the CSG.

CSG Interface

The CSG interface enables you to create a PBX solution that rivals the features and functionality of traditional telephony switches. Current PBX solutions are expensive and proprietary. Using the CSG, you can replace an existing small business PBX. Since it runs on Linux, it inherits all of the power and stability of that operating system. The CSG works with most standards-based IP telephone handsets and software. The CSG also supports analog phones and ADSI-screen phones.

Identifying Communication Ports

The CSG unit consists of up to eight RJ11 analog ports which can be configured as either FXO or FXS ports, depending on the type of modules installed in the CSG model. These ports provide 16ms of analog port echo cancellation. The unit is rated for a total of 8 REN across all FXS ports. Each individual port is rated for up to 3 REN @ 1500ft (450m).
Four 10/100BaseT LAN ports and one 10/100BaseT WAN port provide the functionality to connect to the local network as well as allowing the CSG to act as a router. All the Ethernet ports support auto-MDI/MDX.
An RS-232 console port is also available for additional configuring of the pre-loaded CSG software via direct physical access. The preferred method for configuring the unit is by using the web based interface. You can also configure it remotely using SSH. The CSG is shipped fully configured, but it may be altered for specific applications.

Installing the Hardware

1. Connect an Ethernet cable connected to your network to the Network port on the back of the CSG.
2. Connect an Ethernet cable an IP Phone port. This will be used during the initial configuration of the
CSG.
3. Connect the provided power supply to the unit’s DC connector. The unit immediately receives
power once you connect a power source to it.
4. When the unit completes the boot process, the left-most eight LEDs indicate how the analog ports
are configured. A red light indicates the port is FXO, and a green light indicates the port is FXS. If the light for a port is off, the port is not installed.
The analog port configuration is selected when purchasing your CSG unit.
5. Connect telephones to the analog ports that are configured as FXS ports and connect phone lines to
the analog ports that are configured as FXO ports. If you are using the CSG-500, you can skip this step.
If you are using the CSG-544, do NOT connect analog ports 1-4 to a phone line. Since both the FXS ports and the phone lines supply power, the hardware could sustain damage. This damage is not covered under the AMX standard warranty.
This unit must be connected to the Telecommunications Network in your country using an approved line cord, e.g.: for Australia use only line cords complying with ACA Technical Standard TS008.
This unit must be connected only to the appropriate Telecommunications Network port (as approved for use in your specific country).
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication wiring for network connections.

Telephone System Configuration

This chapter provides information on how to initially set up your telephone system via the CSG Interface. The CSG Interface gives you the ability to set up your telephone system without the need to use command line configuration. After connecting to the CSG, the primary menu is displayed, giving you the ability to configure your system, as well as add features to your call system as your needs change.

Logging On to the CSG

Your CSG should already be connected to an internet or network connection, as described in the Installing the Hardware section on page 9. In the address field of a CSG supported web browser, enter the IP address
assigned to your CSG. The default LAN IP address is 192.168.69.1.
Telephone System Configuration
FIG. 9 CSG Interface Login
To log on to the system enter the following credentials:
Username: admin
Password: <password>
The first time you log on you will be prompted to change your password from the default. You should have already chosen a new password during the installation process. Once the log on process is complete the CSG Interface home page will be displayed.

Subsequent Logins to the CSG

The method described above will work to log onto the configuration tool of the CSG. In addition, you can log onto the CSG using the CSG's Network port once it has been enabled. In this case, open a web browser on a computer which is located on the same network as the CSG. In the address field of the web browser, enter the IP address of the CSG as defined during the initial installation.
Telephone System Configuration
16
CSG SIP Communications Gateway Operation/Reference Guide

Bonjour (Zero-Configuration) Client

You can also log on to the CSG by using a zero-configuration networking client that allows you to determine the unit’s IP address, such as Bonjour or a similar zero-configuration client. Zero-configuration (or Zeroconf, also known as "Bonjour") technology provides a general method to discover services on a local area network. In essence, it allows you to set up a network without any configuration, as described below.
You may need a zero-configuration client to determine the IP address of the CSG. There are many zero-configuration clients available. However, for the purposes of this document, we will refer to Bonjour for Windows. It is free, and widely available for download. If you don’t already have it installed on your PC, download and install Bonjour for Windows before you begin.
Perform these steps to log on to the CSG through Bonjour for Windows:
1. With Bonjour for Windows running on a PC that has access to the LAN on which the CSG resides,
connect the CSG to the network (see the Installing the Hardware section on page 9.)
2. In Bonjour, you will see the unit join the network at power up (FIG. 10). Double-click the CSG link
to access the CSG Login page (FIG. 9).
FIG. 10 Bonjour for Windows - screen
3. To log on to the system, enter the following user name and password:
Username: admin
Password: 1988
As shown in FIG. 10, Bonjour for Windows operates as a plug-in to Internet Explorer (version 7 shown), and is displayed in the IE Explorer Bar. If you have installed Bonjour for Windows, but don’t see the Bonjour toolbar icon, you may need to "unlock" and expand the toolbars to see it.

The CSG Interface

The CSG Interface gives you the ability to configure the basic hardware and dial plan elements you need when initially setting up your system. You must create trunks, system users, conferencing, voice mail, etc. After logging into the CSG Interface, you’re presented with a variety of options on the left side of the page.
FIG. 11 System Status Page
The CSG Interface supports the following browsers:
 Firefox 1.5 through 3.0
 IE 7
 Safari 3.x
 Opera 9.x
Every page of the CSG Interface has two columns. The left column identifies all the elements for which you can program the CSG. The elements listed begin with System Status, which is the first page you see upon logon, and proceed down to Options. Clicking any of the tabs on the left of the page opens the corresponding page in the right column. Many pages have additional information. Click on the information symbol, a blue “i” enclosed in a circle, to get more information about a field or page.
The System Status page is the default page. This page shows you the current version of firmware you are using, the status of any trunk lines you have configured, the realtime status and additional details of all user extensions, including the new and old voicemail message count for each user extension (e.g. Messages: new/ old), and the realtime status of all agents, conference rooms, and parked calls. You can click on most extension definitions to get more information. In addition, the System Status page gives you the ability to log in, log out, pause, and unpause an agent that is associated with one or more call queues.
A user extension will have the status of “Unavailable” when the VoIP account associated with it is not registered to the CSG. The status will not change to “Unavailable” when a user extension has both an analog port and a VoIP account associated with it.
Telephone System Configuration

CSG SIP Communications Gateway Operation/Reference Guide
In the upper right corner of each page you will see the Apply Changes and Logout buttons. Click Apply Changes to save and activate any changes you have made on a page so that you can utilize the changes. Click Logout on any page to exit the CSG Interface.

Analog Hardware Configuration

You must configure your analog hardware according to the needs of your system as part of your initial CSG configuration. The Configure Hardware page gives you the ability to configure both your FXS and FXO ports, as well as your Tone Region, operation mode, message waiting indicator mode (MWI), etc. The number of FXS and FXO ports available for configuration will depend on the CSG model you purchased. Click the Configure Hardware tab to configure your analog hardware.
The Configure Hardware tab will not be available if you ordered a VoIP only model.
FIG. 12 displays the Configure Hardware page.
FIG. 12 Configure Hardware
FXS and FXO ports provide the ability to receive and send calls through the traditional telephone network, or POTS (Plain Old Telephone System). FXS modules provide both dial tone and ringing voltage to an analog phone. FXO modules accept dial tone and provide an interface to the traditional phone lines. You plug a telephone line into an FXO port, and an analog telphone into an FXS port.
On this page you can specify the signalling type for your FXS and FXO ports. You have two choices; either Kewl Start or Loop Start. The Loop Start method uses a short to request a dial tone. All North American home phone lines use loop start signalling. Kewl Start is the same as Loop Start, but is better able to detect disconnects. Select either Kewl Start or Loop Start for each FXS and FXO module. Kewl Start is the default and is preferred for analog circuits in the CSG.
Ground Start signalling is not supported.
You also need to select a tone region, which defines the set of tones (dial tones, ringing tone, busy tone, etc) used in your region. Select your country, or the nearest neighboring country, from the Tone Region drop-down list. The default setting is North America (United States/Canada).
