4.1 Installing the EdgeGate
To install your indoor VoIP Gateway unit:
1. Unpack the EdgeGate unit.
Figure 3-1 shows the connectors on the rear of the AC-282 (copper port) and GW-282
(fiber optic port).
• The AC-282 provides a copper cable connector. The GW-232 and GW-282 provide
a fiber optic connector.
• The RJ-11 telephone ports Phone 1, Phone 2, Phone 3, and Phone 4 connect to the
telephony devices.
• The PSTN (lifeline) port can be connected as a standby to the public telephone
network. In case of power failure, the phone connected to the Phone 1 port will be
automatically switched from VoIP to this line, fo r regular telephone comm unication.
• The LAN 10/100BaseTX and any of the available fiber optic ports connect to the
LAN, to other VoIP Gateway units and to computers.
• The AUX/Console port (not available on all AC-232 products) connects to the serial
port on a PC for configuring the unit.
Figure 3-2, Figure 3-3, and Figure 3-4 show the GW-232 ports.
Console Grounding: The RS-232 cable must be connected to a floating PC
(i.e., laptop) to prevent the unit from being permanently damaged. Telco
Systems offers a console cable for use by service personnel configuring this
product.

3.1 Dial Plan for SIP and H.32 3
5.1.1 Default Dial Plan
A dial plan provides the unit with a map that is used to determine when a complete number
has been dialed. The number is then passed on to the SIP Server\Gatekeeper, which resolves it
into an IP address.
The default dial plan (>#|[2-9]xxxxxxxxx|1[2-9]xxxxxxxxx|x.T ) includes strings separated by
the vertical bar character “|”. Once a match between one of the strings and the keys that have
been dialed is reached, the Gateway contacts the SIP Server\Gatekeeper and attempts to make
a call. The default dial plan includes the string [2-9]xxxxxxxxx meaning that dialed numbers
can be 10 digits long starting with any digit in the range 2-9. The string x.T (or x.t) in the
default dial plan means that after any dialed number and a pause of 4 seconds an attempt t o
make a call is made. The user can use the default dial plan or set up an alternative plan. For
detailed explanation of possible dial plan schemes see following sections.
• To set the dial plan when using the H.323 protocol via the Web, see

This section describes the following dial plan examples:
• Simple Dial Plan
• Basic Dial Plan
• Complex Dial Plan
• Prefix Rule Dial Plan
• Replace Rule Dial Plan
5.1.3.1 Simple Dial Plan Example
The simple dial plan example allows dialing of seven-digit numbers (e.g., 2233445) or an
operator on 0. The dial plan is:
0T|xxxxxxx
meaning that a match is produced if you dial zero followed by a four-s econd delay, or if you
dial any seven-digit number.
5.1.3.2 Basic Dial Plan Example
The basic dial plan allows dialing of any number of digits. The dial plan is:
x.T
This ensures a match against one or more digits. A match is produced when a delay of about 4
seconds follows any number of dialed digits.

5.1.3.4 Prefix Rule Dial Plan
Dial Plan Prefix is used to add a user defined prefix to the head of the dialed number.
Syntax: p(STRING1)STRING2
If a dialed number matches STRING1, STRING2 is added to the head of the dialed number.
Example: p(2x.t)00
This example adds digits 00 to any dialed number beginning with the digit 2.
5.1.3.5 Replace Rule Dial Plan
Dial Plan Replace can be used to prevent a dialed sequence from being sent or a dialed
sequence can be replaced by another sequence.
Syntax: r(STRING,STRING2)STRING3.
If a dialed number matches string1+string2, string1 is replaced by string3.
Example 1: r(0,x.t)33
This example replaces leading 0 with 33 in a dialed number of any string beginning with zero.
Example 2: r([1-3]0,xxx)
This example removes the digits 10, 20 or 30 from dialed numbers of format 10xxx, 20xxx or
30xxx.
Example 3: r(1)345678
This example sets 1 as a shortcut for “345678”. Dialing 1 will be replaced with the number
345678.
5.2 Unders t a nding DHCP
Dynamic Host Configuration Protocol (DHCP) provides a framework for passing
configuration information to hosts on a TCP/IP network. DHCP, based on the Bootstrap
Protocol (BOOTP), adds the capability of automatic allocation of reusable network addresses
and additional configuration options. DHCP captures the behavior of BOOTP relay agents,
and DHCP participants can interoperate with BOOTP participants.
DHCP provides configuration parameters to Internet hosts. DHCP consists of two
components: a protocol for delivering host-specific configuration parameters from a DHCP
Server to a host; a mechanism for allocating network addresses to hosts.
DHCP is built on a client-server model, where designated DHCP Server hosts allocate
network addresses and deliver configuration parameters to dynamically configured hosts.
Throughout the remainder of this document, the term server refers to a host providing
initialization parameters through DHCP, and the term client refers to a host requesting
initialization parameters from a DHCP Server.
DHCP supports three mechanisms for IP address allocation:
• Automatic allocation - DHCP assigns a permanent IP address to a client.
• Dynamic allocation - DHCP assigns an IP address to a client for a limited period of time
(or until the client explicitly relinquishes the address). Dynamic allocation allows
35 of 244
Rev H
INITIAL CONFIGURATION AND BACKGROUND INFORMATION
automatic reuse of an address that is no longer needed by the client to which it was
assigned. Thus, dynamic allocation is particularly useful for assigning an address to a
client that will be connected to the network only temporarily or for sharing a limited pool
of IP addresses among a group of clients that do not need permanent IP addresses.
Dynamic allocation may also be a good choice for assigning an IP address to a new client
being permanently connected to a network where IP addresses are scarce and it is
important to re cla im them when old clien ts are re ti red .
• Manual allocation - a client's IP address is assigned by the network administrator, and
DHCP is used simply to convey the assigned address to the client. A particular network
will use one or more of these mechanisms, depending on the policies of the network
administrator. Manual allocation allows DHCP to be used to eliminate the error-prone
process of manually configuring hosts with IP addresses in environments where (for
whatever reasons) it is desirable to manage IP address assignment outside of the DHCP
mechanisms.
As shown in
Figure 4-1, the parameter negot iation starts with a DHCPDISCOVER broadcast
message from the client seeking a DHCP Server. The DHCP Server responds with a
DHCPOFFER unicast message offering configuration parameters (such as an IP address, a
MAC address, a domain name, and a lease for the IP address) to the client. The client returns a
DHCPREQUEST broadcast message requesting the offered IP address from the DHCP Server.
The DHCP Server responds wi t h a DHCPACK u nicas t message confirming that the IP address
has been allocated to the client.
Figure 4-1 Obtaining an IP Address from a DHCP Server
The client may suggest values for the IP address and lease time in the DHCPDISCOVER
message. The client may include the requested IP addr ess option to suggest that a particular IP
address be assigned, and may include the IP address lease time option to suggest the lease
time it would like to have. The requested IP address option is to be filled in only in a
DHCPREQUEST message when the client is verifying network parameters obtained
previously.
If a server receives a DHCPREQUEST message with an invalid requested IP address, the
server should respond to the client with a DHCPNAK message and may choose to report the
problem to the system ad ministrator. The server may include an error message in the message
option.

Rev H
INITIAL CONFIGURATION AND BACKGROUND INFORMATION
For setting the Gateway as a DHCP client, see Configuring the VoIP Gateway via Telnet or
CLI Console on page
65, or Configuring the VoIP Gateway via the Web on page 83.
5.2.1 When Should Clients Use DHCP
A client should use DHCP to reacquire or verify its IP address and network parameters
whenever the local network parameters may have changed (e.g., at the Gateway boot time or
after a disconnection from the local network), as the local network configuration may change
without the client's or user’s knowledge.
If a client has knowledge of a previous network address and is unable to contact a local DHCP
Server, the client may continue to use the previous network address until the lease for that
address expires. If the lease expires before the client can contact a DHCP Server, the client
must immediately discontinue use of the previous network address and may inform local users
of the problem.
5.3 Understanding NAT and NAPT
The goal of the Network Address Translator (NAT) is to provide functionality as if the private
network had globally unique addresses and the NAT device was not present. Basic NAT
allows a one-to-one mapping between one private address and one public address. In its
simplest configuration, the NAT operates on a router connecting two networks together. One
of these networks (designated as inside) is addressed with either private or obsolete addresses
that need to be converted into legal addresses before packets are forwarded onto the other
network (designated as outside). The translation operates in conjunction with routing, so that
NAT can simply be enabled on a customer-side Internet access router when translation is
desired.
Network Port Address Translator (NAPT) maps a single public address to one or many
internal addresses and all network IP addresses on the connected computers are local and
cannot be seen by the outside world.
NAPT is an extension to NAT in that NAPT uses TCP/UDP ports in addition to network
addresses (IP addresses) to map many private network addresses to a single outside address.
A VoIP Gateway behind NAT might require special settings. For solutions in SIP, see
Initiation Protocol (SIP) Configuration via Web on page 143.
Session
5.4 Unders t a nding NTP
The NTP is designed to synchronize clocks among devices in a network. NTP runs over User
Datagram Protocol (UDP), which runs over IP. An NTP network usually gets its time from an
authoritative time source, such as a radio clock or an atomic clock attached to a time server.
NTP then distributes this time across the network. NTP is extremely efficient; no more than
one packet per mi nute is necessary to synchronize two devices to within a millisecond of one
another.
NTP is a tiered time distribution system with redundancy capability. NTP measures delays
within the network and within the algorithms on the machi ne on which it is running. Using
these tools and techniques, it is able to synchronize clocks to within milliseconds of each other
when connected on a Local Area Network and within hundreds of milliseconds of each other
when connected to a Wide Area Network. The tiered nature of the NTP time distribution tree
enables a user to choose the accuracy needed by selecting a level (stratum) within the tree for
37 of 244
Rev H
INITIAL CONFIGURATION AND BACKGROUND INFORMATION
machine placement. A time server placed higher in the tree (lower stratum number), provides a
higher likelihood of agreement with the UTC time standard.
You should use the security features of NTP to avoid the accidental or malicious setting of an
incorrect tim e by using an encrypted authentication mechanism.
NTP has become a standard for internet time synchronization. Most importantly, there are
more than 100000 free NTP time servers in the world.
For setting the IP address of the NTP server using the Web, see Clock Localization on pa ge
111.
5.4.1 Daylight Saving Time (Summer Tim e)
You can configure your Gateway to observe the Daylight Saving Time (DST) in your area.
Once configured, whenever the system time is updated using a time server located in a
different time area, it will be automatically corrected with the local DST time offset.
The DST is followed by the U.S. standards. You can have the Gateway advance the clock one
hour at 2:00 a.m. on the first Sunday in April and move back the clock one hour at 2:00 a.m.
on the last Sunday in October. You can also explicitly specify the start and end dates and times
and whether or not the time adjustment recurs every year.
For enabling automatically adjust the internal clock to daylight saving time according to the
local time zone via Web see
Clock Localization on page 111.
5.5 Unders t a nding Syslog
The system message logging can save messages in a Syslog server. The system message
logging facility:
• Provides you with logging information for monitoring and troubleshooting.
• Allows you to select the types of logging information to be captured and the destination of
that information.
You can specify which system messages should be executed, based on their severity level (see
Table 4-3). You can monitor system messages by viewing the logs on a Syslog server.
Table 4-3 Log Message Severity Levels
Severity Level Keyword Description
0 emergency Internal error occurred. The Gateway reached a crash state and
cannot continue to operate.
1 alert Internal error occurred. The Gateway might operate incorrectly.

5.5.1 Remote Logging
To enable remote logging on a UNIX Syslog host facility, follow these steps:
1. Configure the Syslog host to accept and log messag es.
2. Enable remote logging by using the enable syslog command.
3. Configure remote logging by using the following command:
config syslog {add} <ipaddress> <facility> {<severity>}
4. Specify the following:
— ipaddress — The IP address of the Syslog host.
— facility — The Syslog facility level for local use. Options include local0 through local7.
— severity — Filters the log to display message with the selected severity or higher (more
critical).
Severities include (in order) emergency, critical, alert, error, warning, notice, info, and
debug. If not specified, all messages are sent to the Syslog host.
5.6 DNS Resol ver
The Domain Name System (DNS) is the means by which Internet domain names are located and
translated into Internet Protocol addresses. A domain name is a mnemonic “handle” to an Internet
address.
Because it would be impractical to maintain a central list of domain name/IP address
correspondences, the lists of domain name s and IP addresses are distributed throughout the Internet
in a hierarchy of authority. There is probably a DNS ser ver withi n close geo graphic pr oximity t o
your access provider that maps the domain names in your Internet requests or forwards them to
other servers in the Internet .
Figure 4-2 demonstrates how the DNS operates. The client enters a domain name
(www.domainname.com) into his brows er. The browser contacts the Client’s ISP to obtain the IP
address corresponding to the domain name. The ISP first tries to find the answer in its own “cached”
data. If it finds the answer, it returns it to the client's browser. Since the ISP isn’t in charge of the
DNS, and is just act ing as a “ DN S rel ay ”, th e an sw e r is m ark ed “n on-authoritative”. If the answer is
not found or if it is too old (past the TTL), the ISP DNS contacts the nameservers for the domain
directly for the answer. If the nameservers are not known, the ISP looks for the information at the
‘root servers’, or ‘registry servers’. For com/net/org, these start with a.gtld-servers.net.

You can define up to two DNS servers. If a query to the primary address fails to be resolved
after three attempts, the next gateway address is queried.
To use DNS, you must have a DNS server present on your network.

5.7 IP Fragmentation
The IP protocol is designed for use on a wide variety of transmission links. Although the
maximum length of an IP datagram is 64K, most transmission links enforce a smaller
maximum packet length limit, called a MTU. The value of the MTU depends on the type of
the transmission link. The design of IP accommodates MTU differences by allowing devices
to fragment IP datagrams as necessary. The receiving device is responsible for reassembling
the fragments back into the original full size IP datagram.
IP fragmentation involves breaking a datagram into a number of pieces that can be
reassembled later. The IP source, destination, identification, total length, and fragment offset
fields, along with the "more fragments" and "don't fragment" flags in the IP header, are used

6.1 Keypad Configuration (Enabled only on 232 Gateway
products)
Basic configuration commands such as setting factory defaults and changing the IP mode from
DHCP to fixed, or hearing the current IP address announced, can be done by entering
configuration commands using the telephone keypad. Use this option if you have lost normal
access to the Gateway via a PC. The following commands are active ten minutes from boot on
the telephone connected to line 1.
To set the factory defaults:
Dial ##3332858 (D,E,F,A,U,L,T). Once the command is accepted, the Management LED on
the front panel will glow a steady green and after about 30 seconds the unit will power up with
factory defaults.
To set the IP mode:
To change the IP mode from DHCP to fixed or vice-versa, dial ##3427937 (D,H,C,P,Y,E,S)
for DHCP or ##342766 (D,H,C,P,N,O) for fixed IP 10.1.0.54 Mask 255.255.0.0. The
Management LED on the front panel will glow a steady green for about 3 seconds and the unit
will boot with the required IP setting.
To hear the current IP address announced over the headset:
Dial ## 472337 (I,P,A,D,D,R).
6.1.1 Keypad Configuration for MGCP
If the Keypad Configuration option is used before the Gateway is registered with the Call

8 Upgrading the Gateway
Firmware and Downloading
Configuration Files
The Gateway, when shipped, has code already installed in its Flash ROM memory and is ready
to run. This section describes the process for upgrading the Gateway’s firmware with a new
version of the ROM image. New ROM images can be obtained from the vendor of your
Gateway. This section also describes how to down load co nf ig uration fi les to the Gateway.
A convenient way to set up the Gateway configuration is to download the configuration file to the
Gateway.
You can set downloading of the configuration file to the gateway to occur in any of the following
three ways:
• Manual download
The configuration file and upgrade versions are downloaded directly via Telnet (see
Downloading the File Manually using Telnet on pa ge 52 or the Web (see Downloading Code
Versions over the Web via the TFTP Server on page 53 and Downloading Code Versions over
the Web via the HTTP Server on page 56).
• DHCP server auto confi gurat ion (see DHCP Automatic Configuration on page 60)
The configuration file and upgrade versions are downloaded automatically using a DHCP
server that is bas ed at the provider’s network. The TFTP/HTTP server IP address and the file
name are provided by the DHCP server during the Bootp process and at half lease time. You
can set DHCP server Automatic Configuration either via the Web (see
Automatic Configuration via the Web on page 60) or via T elne t (s e e Setting DHCP Automatic
Configuration via Telnet on page 61).
• Fixed (provisioned) TFTP/HTTP Auto Configuration (see Fixed (Provisioned) HTTP or
TFTP Automatic Configurati on on page 62)
The configuration file and upgrade versions are downloaded automatically as needed during
boot and at fixed polling intervals using a TFTP/HTTP server based at the provider’s network.
The TFTP/HTTP se rv er IP address and the file name a re prov is ion ed in to th e g at eway . Y ou can
set Fixed Automatic Configuration either via the Web (see
“Root” C onf i gurat i on F il e vi a t he Web on page 63) or via Tel net (see Set ti n g the TFT P Ser ver
“Root” Configuration File v ia Telnet on page 63).
Two kinds of configuration files can be downloaded:
Setting the TFTP/HTTP Server
Setting DHCP
1. “Root” configuration file - the first file to be downloaded. This file can include any of the
Gateway configurat ion par am eters and three exec ution flag s. Each ex ecution f lag, when set, can
initiate one of the following possible actions:
• Downloading a secondary Gene ral conf iguration file
• Upgrading the Gateway App licatio n fi rmw are
• Upgrading the Gateway Loader firm ware
51 of 244
Rev H
UPGRADING THE GATEWAY FIRMWARE AND DOWNLOADING
CONFIGURATION FILES
The “root” configuration file normally includes specific configuration parameters for the
Gateway being load ed.
Using the Gateway’s MAC address we can identify each Gateway uniquely and therefore
download to each Gateway its own “root” configuration file with the specific required
parameters.
2. “General” configuration file - The second configuration file will include general parameters,
common to a few or all the Gatew ay units in the netwo rk a nd also the f ollowing execution f lags.
• Upgrading the Gateway App licatio n fi rmw are
• Upgrading the Gateway Loader firmware
The configuration files can also includ e:
• IP address of the TFTP/H TTP
• Firmware file names
• Firmware file
NOTE
If the Firmware file versions (APP_VERSION, LDR_VERSION) parameters are
used, a firmware upgrade will take place on ly if the Firmware file version is
different from the current firmware version.
The name of the “root” configuration file must be of the format ipg_xxxx.cfg.
Configuration files must include header “; Configuration Parameters. Don't
edit this line !!! “. You will find an example for this file in this document or
see file ipg_example.cfg.
To control when the new configuratio n p arameters will be included use the
‘Automatic Configuration ID’.
NOTE The Gateway’s configuration par ameters are kept and are valid for all
firmware upgrades. Setting to defaults is recommended only

9 Configuring the VoIP Gateway
via Telnet or CLI Console
Use the Command Language Interface (CLI) commands at the terminal to configure basic
parameters such as the unit’s IP parameters and, optionally, any other parameters.
Any workstation with a Telnet facility should be able to communicate with the Gateway over
the network. Two Telnet sessions can be opened concurrently with the Console. The Telnet
session will be disconnected after a specified time of inactivity.
9.1 Starting a Telnet Session
Before you can start a Telnet session, you must set up the IP parameters as described in
Accessing the CLI below, or in Assigning an IP Address to the VoIP Gateway using Web
Configuration on page 83.
To open the Telnet session, you must specify the IP address of the VoIP Gateway that you
want to manage. Check the user manual supplied with your Telnet facilit y i f yo u ar e uns ure of
how to do this.
Once the connection is established, you will be prompted to log in. VT100 emulation and
V100 keys must be used.
9.2 Accessi ng t he CLI
To access the CLI, connect a terminal to the unit (connecting a t erminal is not available
for 232 products) and set it up as follows:
1. Connect the special RJ -45 serial cable to the AUX/Consol e connector on the back panel.
Connect the other side of the cable to a st andard VT-100 or compatible terminal, or to a
terminal emulator. The cable length must not exceed 10 meters.
The cable pin-out is as follows:

CONFIGURING THE VOIP GATEWAY VIA THE WEB
11 Configuring the VoIP Gateway
via the Web
You can configure the VoIP Gateway remotely via a PC Web browser. To do so, enter the IP
address of the VoIP Gateway into the Web browser and access the VoIP Gateway (e.g.,
http://172.25.4.26). The VoIP Gateway can be configured to use a fixed IP address or to
acquire an IP address from a DHCP server. T he VoIP Gateway is factory set to acquire an IP
from a DHCP server (use the show command in main CLI mode to see the current IP).
To update a setting, enter the requi red settings on a web page and then save the changes by
clicking on the Save button at the bottom of the page. Once all settings have been saved,
select the Reset option on the left-hand side of the Web page to reset the VoIP Gateway and
activate the new settings.
11.1 Assigning an IP Address to the VoIP Gatew ay using
Web Configuration
To change the mode from using DHCP to fixed IP, or to assign a different fixed IP
address, configure the unit as follows:
1. If th e VoIP Gateway unit is using DHCP (DHCP is the default setting. In some cases
after setting Fixed IP the address could be 10.1.0.54):
• Connect the VoIP Gateway to a network with a DHCP server.
• Configure a PC with an IP address on the same subnet.
2. Connect your PC to the VoIP Gateway (or via a hub or a switch).
3. Enter the IP address of the VoIP Gateway unit into the PC Web browser.

7. Scroll down to the bottom of the Web page, and click the Save Settings button.
8. Select Reset in the vertical menu bar to reset the unit (see Completing the VoIP Gateway
Configuration on page 129).
You can now use the new IP address.
11.1.1 Setting the VoIP Gateway to be a DHCP Client
To use a DHCP server to supply an IP address to the VoIP Gateway, you must first configure
the unit appropriately by selecting the Use DHCP to obtain LAN configuration option, as
described in step 6 above.
We recommend that you configure your DHCP server to assign the same address to the VoIP
Gateway unit each time it is powered up. This will help to track the available V oIP Gateway
units during the VoIP Gateway and Gatekeeper configuration.
When the VoIP Gateway unit is powered up, it queries the DHCP server for an IP address.
You must know this “new” IP address, assigned by the server, in order to access the VoIP
Gateway Web Setup Facility. To determine which IP address refers to your VoIP Gateway,
see the IP address in the CLI opening screen that appears when the unit boots with a t erminal
(see
Upgrading the Gateway Firmware and Downloading Configuration Files on page 51).
11.1.2 Using VoIP Gateway with a Fixed Address
If you do not have access to a DHCP server, and your Gateway is configured to use a DHCP
server, or if you do not know the IP address used by the Gateway, configure your Gateway
via a terminal connected to the AUX/Consol e por t (not avaible for 232 products, use Keypad
Configuration). You can also view the IP address or disable DHCP.
11.2 VoIP Pr ot oc ol Conf iguration
Once the VoIP Gateway unit has obtained its IP address, you can use the Web Configuration
to configure the VoIP Gateway. To be able to place calls, you must configure the VoIP
protocol parameters, appropriate to the VoIP protocol installed in the VoIP Gate way (H.323,
MGCP or SIP). Refer to sections which detail H.323 configuration, MGCP configuration, or
SIP configuration.
11.3 Autoconfiguration
To enable and set automatic configuration (see Upgrading the Gateway Firmware and

VLANs (Virtual LANs) logically group a set of stations to communicate as if they were on
the same LAN segment. Traffic between VLANs is restricted. Unicast and broadcast traffic is
forwarded only to LAN segments of the same VLAN. The VoIP Gateway enables you to
configure up to sixteen 802.1Q-compatible VLANs on the 282/482/483S/483D model and up
to 8 VLANs on the 232 nodel. A VLAN is identified by a unique number from 1 to 4095
(VLAN ID). By default, the VLAN configuration is disabled and traffic is free to travel
between all VoIP Gateway ports.

VLAN tagging is required to identify traffic from more t han one VLAN on the same port. A
“tag” is simply the VLAN identification number (VLAN ID), as specified in the 802.1Q
standard. The tag is included in the packets forwarded across the LAN. You can allow the
VoIP Gateway to connect to non 802.1Q-compliant devices by adding/removing the tag from
packets according to tag def in it ion s in the VL A N con f ig u rat io n table.
11.4.3 VLAN Configuration Proce dure on the VoIP Gateway
Use the TAB key or click to move around the table in the VLAN configuration page . The
VoIP Gateway is factory set with VLAN ID – 1 assigned by default to all the ports of the unit.
Each port must have a default ID. All packets received on the VoIP Gateway ports without a
VLAN tag will inherit the default VLAN ID of the receiving port as their VLAN ID.
You can use the VLAN configuration page to define new VLANs.
To define a new VLAN, proceed as follows:
1. In the VLAN column, enter the new VLAN ID.
NOTE For EdgeGate 282/282S/482S/483S/483D when IGMP is enabled, the Gateway
uses VLAN IDs in the range 1792-1842 internally. Therefore, VLAN IDs in this
range should not be used by the user.
2. In the Ports table, in the row corresponding to the new VLAN ID:
VLAN (see figure below):
• Enter T if packets of the VLAN are to be transmitted from the port with a VLAN
tag in the packet (Tagged).
• Enter U if packets of the VLAN are to be transmitted from the port without a
VLAN tag in the packet (Untagged).
Note: The 232 product supports four LAN ports and up to eight VLANs.

Once the VLAN configuration table is set and VLAN Enable is selected, packets received at
an VoIP Gateway port will be forwarded only to ports of the same VLAN (ports that have
their port member field set to “T” or “U” for that VLAN).
Traffic addressed to the VoIP Gateway unit (Web management or VoIP protocol frames) will
be received and transmitted on any of the defined VLANs.

11.5 Voice and Management Services Configuration
To further refine the VLAN configuration and assign a VLAN per protocol, for frames where
the VoIP Gateway is the source or the destination, use the Voice and Management Services
Configuration screen. The user can assign VLAN and priority tags to outgoing frames. This
will help devices such as switches and routers in the LAN to serve the frames with higher
priority queues and with lower delays. Service VLANs can be defined also for security
reasons. With service VLANs for IGMP, the VoIP Gateway can support multi-IGMP queries
and multicast streams.

CONFIGURING THE VOIP GATEWAY VIA THE WEB
The VoIP Gateway supports IGMP Snooping. This feature reduces the unnecessary use of
bandwidth by IP multicast traffic in LAN TV and other applications. If an IGMP querier
exists on the LAN, the VoIP Gateway can listen to the reports from the IGMP hosts to the
multicast router/querier and discover which multicast group hosts are connected to the VoIP
Gateway ports. It then maps the connections between multicast router/querier and multicast
group hosts. This enables the Gateway to direct multicast group traffic directly to the ports of
the hosts belonging to the multicast group, thereby eliminating traffic that has no mapped
destination.
NOTE For EdgeGate 282/282S/482S/483S/483D products, when IGMP is enabled, the
Gateway uses VLAN IDs in the range 1792-1842 internally. Therefore, VLAN
IDs in this range should not be used by the user.

Gateway ports. You may enter values in the range 5-100 (0.5-10
seconds). The default value is 10 (one second). A smaller value
allows less time to detect the leave of the last member of a
multicast group. See Note
The number of group-specific queries sent before the unit assumes
that there are no local members. The default value is 2, and the
allowed range is 1-9. The number is effective only if Immediate
Leave is not selected.

Enable IP Multicast
Flooding
Min IP address
Max IP address
This field defines how the VoIP Gateway treats IP multicast frames
that were not requested by any host.
If IP Multicast Flooding is disabled, then any IP multicast frame
within the range specified by Min IP address and Max IP address
will be filtered if no host reports that it belongs to its multicast group.
If Multicast Flooding is enabled, then an IP multicast frame without
any host report is flooded to all host ports.
These fields specify the filtering range of unrequested frames if IP
Multicast Flooding is disabled.
NOTE
The VoIP Gateway assumes that the Last Member Query Interval used by the
Querier is the same as the Last Member Query interval configured in the VoIP
Gateway. Using a larger interval by the Querier could cause a short period of
flooding of group multicasts.

12 Configuring Security via the
Web
In today’s networks, security is very important for protecting the Gateway and your local
network from hackers. The f oll owi ng s ecur ity features are available in the Gateway using the
Web management interface:
• Password - to prevent access to the Gateway’s configuration.
• Advanced security - specifying a list of IP addresses that can manage the Gateway (up to
eight IP addresses can be set in the IP address list).
• DHCP security – to receive an IP address and other configuration parameters only from a
DHCP server that is listed in the IP address list (up to eight IP addresses can be set in the
IP address list).
• Blocking the Gateway management via HTTP and/or Telnet on the LAN interfaces.
• Support for User Mode (limited Web access). Option available only for 232 products.
• Installing an Encryption Key in order to use encryption with a configuration file.
