Applications Setup
Clicking the Others button on the Setup menu displays the Applications Setup dialog box. This
dialog box lets you to enable SNMP Agent (the default is 
disabled) and set up all the necessary
parameters; enable or disable various remote configuration methods such as TFTP (Trivial File
Transfer Protocol) Server, Web Server, Dumb Terminal Management, and Telnet Server; and assign a
Password to the MultiVOIP for Internet security. These applications enable remote viewing and
changing of the MultiVOIP configuration, or updating firmware, from anywhere on the connected
internetwork.
Verify that the desired applications are enabled (checked). The default condition is all applications are
checked. To disable a given application, click to uncheck the check box and disable support.
SNMP related operations can be performed only when the SNMP Agent is enabled (checked) on this
dialog box. The IP address of the system (i.e., SNMP Manager) that will receive the Traps from the
MultiVOIP should be entered in the IP Address field in the Trap Manager group. The Community
Name of the SNMP Manager receiving the Traps can be a maximum of 19 characters and 
is case
sensitive. The default Port Number of the SNMP Manager receiving the Traps is 162. The MultiVOIP
currently supports a maximum of two community users at a time, and they can be assigned either
Read/Write or Read Only rights.
The Password group enables you to enter a password, up to 13 alphanumeric characters, to be used
for Internet Security. Once the password is entered (in the MultiVOIP Password field) and confirmed
(in the Confirm Password field), remote users will be queried to enter the password before gaining
access to the MultiVOIP.
For more information on using these applications, click the on-line Help button or refer to Chapter 5,
Remote Configuration and Management.

Viewing Statistics
The Statistics dialog box enables you to view statistics for major events of the MultiVOIP operation.
This dialog box is accessed by clicking the Statistics button on the MultiVOIP 200 Setup menu.
Statistics can be a helpful troubleshooting tool. For example, viewing the Voice Channel statistics you
can see the attempted and completed calls, call duration, average call length, bytes/packets sent and
received, etc.
IP Statistics
IP is a connection-less network protocol residing in the network layer of a conventional OSI layered
model (for more information on this model, refer to Appendix A). Depending on what is going on at
the application layer, IP will typically use one of two transport layer protocols. User Datagram
Protocol (UDP), a connection-less transport layer protocol used with TFTP or SNMP; and Transport
Control Protocol (TCP) is a connection-oriented transport layer protocol used with FTP, Telnet, and
SNMP.
UDP makes use of the port concept and has no measures for flow control, reliability, or error
recovery. It is used when the full services of TCP are not required, and the reliability measures must
be assumed by another layer.
TCP works well in environments where the reliability measures are not assumed by other layers. It is
connection-oriented and has a full range of services.
For the most part these statistics are informational, and their use as a troubleshooting tool will be
contingent on the applications running in the upper layers. For example, if you were having problems   
						

							53 Chapter 4 - MultiVOIP Software
connecting to the MultiVOIP’s web server, you would look under the TCP section to see if any
connections are being established.  If not, that may indicate the web server is not enabled.  Or, if you
were having problems establishing a remote connection through TFTP, you could look in the UDP
section to see if any packets are being received.  If not, you may need to review your network
addressing.
SNMP Statistics
The SNMP Statistics dialog box provides statistical information on Simple Network Management
Protocol (SNMP).
SNMP is an application layer protocol that facilitates the exchange of management information
between network devices.  There are three key components in SNMP: the devices that are to be
managed, agents, and the network management systems.  The managed device is the network
device, like a router.  The agent is the software module residing in the managed device pertaining to
network management.  The network management system runs the SNMP application that controls the
managed devices and monitors their status.  Four primary operations -- Set, Get, Get Next, and Trap -
- are performed using SNMP.

This dialog box is accessed from the Logs button on the Statistics dialog box.
The Log Entries dialog box displays each call as a sequentially numbered Event with the date, time,
duration of the call, the status of the call (Successful or Unsuccessful), Mode (Voice  or Fax), and the
from and to numbers.
Viewing Log Entry Details
The Log Entry Details dialog box displays the status of a completed call.  This dialog box displays
the same details as the Call Progress dialog box after a call is completed.

Upgrade Procedures
Whenever you upgrade your version of the MultiVOIP software, you must first install the new
software on your PC. Then, download the Firmware, the Factory Defaults, and/or the Voice Coders to
upgrade the MultiVOIP itself.
Before starting the upgrade process, view the current configuration and write down important data
such as your IP address, phone book contents, and voice channel configurations; these settings
must be put back in place after the software has been upgraded.
Two utility programs included in the MultiVOIP software are to be used only after the unit has been
repaired or upgraded. They are 
Download Firmware and Download Voice Coders.

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 RS232 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 200 | Configuration Port Setup, or double click on the Configuration Port icon
in the MultiVOIP 200 program group.
5 The MultiVOIP 200 Setup dialog box is displayed.
