The Phone Directory Database in a H.323 Gatekeeper network only displays the station information
and station identification of the local unit.  The station information and identification have to be
entered in conjunction with the Gatekeeper administrator so that the identification of the endpoint is
the same.  To add an entry to the Phone Directory Database, click  Add and the Add/Edit Phone
Entry dialog box displays.
The Add/Edit Phone Entry dialog box contains two groups of information; the Station Information
which contains the phone number, description window which can be left blank, and the voice channel
number.  The Station Identification group contains the H.323 ID and the IP Address window for the IP
Address of the MultiVOIP assigned the phone number.  The Port number of the MultiVOIP unit
communicating with the Gatekeeper.  This port number has to match the port number pair used by
the Gatekeeper.  If the port number on either end is changed, communication between endpoint and
the Gatekeeper is lost.  Click Copy From in the Add/Edit Phone Entry dialog box to add additional
phone entries.
The Station Information identifies the calling unit by the phone number, a description if you choose,
and voice channel of the unit doing the calling.  The Phone Number does not have to be a
conventional telephone number.  It can be a three digit number such as 101.  The Description box
and the H323 ID box may contain the same information.  It is recommended that the Description box
be left blank and the identifying information be enterred in the H323 ID window. The voice channel
box defines the voice channel associated with the telephone.
The Station Identification group allows you to define the MultiVOIP unit by entering the H323 ID
which can be the same, as for example, your name in your local telephone book listing.  The
Gatekeeper associates the H323 ID with the address of the local unit in the IP Address window.  The
Port number 1720 is the port of the MultiVOIP communicating with the Gatekeeper.
The Station Information and Identification of the MultiVOIP unit have to be identical to the information
used by the Gatekeeper in order for the MultiVOIP unit to be registered with the Gatekeeper.  The
Gatekeeper can allow an open registration or a secure registration in which the endpoints are pre-

defined by the Gatekeeper.  The registration method is determined by the Gatekeeper administrator
and will require communication with each endpoint in order to develop the H.323 compatiable
network.
The Phone Directory Database for the local unit contains the local phone numbers, destination details
of the IP address, port number, and channel number of the local unit.  The description is the same as
the entry in the H323 ID entry in the Add/Edit Phone Entry dialog box.
Changing IP Parameters
The IP Setup dialog box establishes the IP address for the local Ethernet LAN and defines the
Internet gateway address. The IP Setup dialog box is accessed by clicking IP on the MVP110 Main
menu.
With IP Setup dialog box displayed you can change the status of differentiated services, the Ethernet
Frame Type, the IP address and IP Mask of your H.323 endpoint, and the Gateway Address of the IP
address of the device connected to the Internet.
Selecting the Enable Diffserv check box enables Differentiated Services. Differentiated Services
provides priority to voice packets so that they are not delayed whenever large data files need to be
downloaded. Check with your systems administrator to determine if any routers in the VOIP network     
						

							53 Chapter 4 - MultiVOIP Software
support this feature. If so, enable this function.
The Frame Type list enables you to change the Ethernet Frame Type so that it matches your IP
network.  If the current entry does not match your IP network, select the Frame Type from the Frame
Type list. The Frame Type choices are TYPE_II and SNAP.
The Port Address group enables you to change the unique IP Address and IP Mask of the local
LAN.
The Gateway Address group enables you to change the gateway IP Address of the device
connected to the Internet/Intranet.
Viewing Call Progress
The Call Progress dialog box is a read-only screen that displays the status of a call in progress. This
dialog box is accessed from the MVP110 Setup menu by clicking the Call Progress button.
The ratio of Packets Lost versus Packets Received provides a general indication of the integrity of
the Internet connection. To reduce the frequency of lost packets, select a low-bit-rate coder, such as,
G.723 or Netcoder. In addition, enabling the Forward Error Correction option on the Voice/Fax tab on
the Channel Setup dialog box will enable the MVP110 to recover many of the lost packets.
The Jitter value (measured in milliseconds) indicates the mean deviation of the difference in packet
spacing at the receiver compared to the sender for a pair of packets.

Applications Setup
Clicking Others on the Setup menu displays the Applications Setup dialog box. This dialog box
allows 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
MVP110 for Internet security. These applications enable remote viewing and changing of the MVP110
configuration, or updating firmware, from anywhere on the connected internetwork.
Verify that the desired applications are selected.  All applications are selected by default. To disable a
given application, clear its check box.
SNMP related operations can be performed only when the SNMP Agent check box is selected on this
dialog box. The IP address of the system (i.e., SNMP Manager) that will receive the Traps from the
MVP110 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 MVP110
currently supports a maximum of two community users at a time, and they can be assigned either
Read/Write or Read Only rights. Note: if you have SNMP client software and enable SNMP Agent,
you can (in the lower right corner of the dialog box) choose to read logs through the SNMP Manager
instead of the COM port.
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 and confirmed, remote users will be queried to
enter the password before gaining access to the MVP110 for configuration purposes.
Note: If you forget your password, contact Technical Support for instructions.
For more information on using these applications, refer to Chapter 5, Remote Configuration and
Management.

Viewing Statistics
The Statistics dialog box enables you to view statistics for major events of the MVP110 operation.
This dialog box is accessed by clicking Statistics on the MVP110 Main menu.
The Voice Channel statistics shows the attempted and completed calls, call duration, average call
length, bytes/packets sent and received. These statistics can be a helpful troubleshooting tool.
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), 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.
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 connecting to the
MVP110’s web server, you would look under the TCP section to see if any connections are being     
						

							56 Chapter 4 - MultiVOIP Software
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: (1) the devices that are to be
managed, (2) agents, and (3) 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.
Viewing Logs
The Log Entries dialog box displays a chronological history of all calls into and out of this unit. This
dialog box is opened by clicking Logs on the Statistics dialog box.     
						

							57 Chapter 4 - MultiVOIP Software
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.
Viewing Channel Totals
The Channel Totals dialog box displays Outgoing and Incoming calls with their Attempted and
Completed numbers for each channel on this MVP110.  The Total Connected Time for the channel is
also displayed.  This can provide you with a sense of successful call completions on each channel of
the unit.     
						

							58 Chapter 4 - MultiVOIP Software
Reports
A report of the contents of the Log Entries dialog box can be generated using the Windows Notepad
accessory and then printed from your local PC.  The report is generated by entering the To and From
dates in the Report Generation dialog box and then clicking Generate. This function provides a hard
copy of the Log Entries dialog box.
