Introduction
This chapter provides procedures for viewing or changing the configuration of a remote unit.  Two
methods are provided to access a remote unit; the first method is modem based and the second
method is using IP.  Within the IP method, three applications can be used: 1) LAN-Based using TFTP
(Trivial lFile Transfer Protocol), 2)Telnet as a client application, or 3) a standard web browser on the
Internet.
Remote Configuration
Remote configuration requires the MultiVOIP software to be loaded on the local PC.  The local PC
then controls the remote MultiVOIP either via the modem connection or the LAN.
Modem-Based
To remotely configure a MultiVOIP, a local PC needs to be connected to a dial-up line and the
MultiVOIP software configured to call the remote MultiVOIP. The remote MultiVOIP needs to have a
modem connected to a dial-up line and the Command Port. Once the connection to the remote unit is
made, you can change the configuration as you see fit. Once the configuration is changed, you can
down load the new configuration to the remote MultiVOIP. Refer to the Modem-Based Remote
Configuration Procedure in this chapter to remotely configure a MultiVOIP.
1 At the remote site, remove the serial cable from the PC to the Command Port connector on
the back panel of the MultiVOIP.
2 At the remote site, connect a special cable (Remote Configuration Cable) from the Command
Port connector on the back panel of the MultiVOIP to the RS-232 connector on the modem.
The special cable is a serial cable with male connectors on both ends. Refer to Appendix B
for cable details.
Connect the modem to your local telephone line.
Provide your telephone number to the person verifying your configuration.
Configure the remote modem for 19200 baud and turn on Force DTR.
3 At the main site, connect your local PC to a modem that is connected to a dial-up line.
4 Install the MultiVOIP software on the local PC. When installed, click Start | Programs |
MultiVOIP | Configuration Port Setup, or double click on the Configuration Port icon in
the MultiVOIP program group.

LAN-Based 
The LAN-based remote configuration requires a Windows Sockets compliant TCP/IP stack. TCP/IP
protocol software must be installed and functional before the configuration program can be used.
1 You must assign an Internet (IP) address for the PC and for each node that will be managed
by the configuration program. Refer to the protocol software documentation for instructions
on how to set the IP addresses.
Once you have completed this step, you should be able to use the protocol Ping command
for the PC host name. You should also test the network interface configuration by Pinging
another TCP/IP device that is connected to the network.
2 Install the MultiVOIP software on the local PC. When installed click Start | Programs |

Remote Management
This section describes typical client applications that can be used to configure the MultiVOIP
remotely. It is important to note that although any subsequent changes to configuration can be made
using these applications, the initial setup and configuration of the MultiVOIP must be done on the
local PC, using the MultiVOIP software provided with your unit.
Although establishing access to the MultiVOIP varies between applications, the configuration
functions mirror those of the MultiVOIP software. For more information on MultiVOIP software, refer
to Chapter 4 - MultiVOIP Software.
Telnet
A typical Telnet client application is described next. The MultiVOIP has a built-in Telnet Server that
enables Telnet client PCs to access the MultiVOIP. A typical Telnet client is allowed to configure the
MultiVOIP.  In addition, the MultiVOIP can be remotely accessed and configured from any where on
the Internet through its Web interface.  A typical TCP/IP program group is shown below with a
Tcpman icon and a Telnet icon.
The TCP/IP stack has to be loaded before the Telnet client (a Windows application) will run. The
Telnet Server option has to be selected from the Applications Setup dialog box using the MultiVOIP
Configuration icon. Double click on the Telnet icon (or shortcut) and a blank Telnet screen is
displayed. Click Connect | Remote System and the Connect dialog box is displayed. Select (or
enter) a Host Name (the IP address of the MultiVOIP).In this example, the Host Name is
