Overview

Panasonic PBX with VoIP Gateway Card will allow
organisations to route both voice and fax communications
over digital data net works.

The V oIP Gateway Card, designed to be easily integrated into
existing IP networks, seamlessly bridges Public Switched
Telephone Network (PSTN) and analogue telephones with
digital data networks without interrupting pre-existing data
communications. Because comm unications do not take place
over con ventional telephone networks, the high cost of long
distance communications is virtually eliminated.

1.1 Example Network Diagram

1.1 Example Network Diagram

The following diagram illustr ates a simple VoIP network connecting PBXs at 2 locations. The VoIP
Gateway Card converts outgoing voice or fax signals into IP packets for transmission. On the
incoming side, it reverses this process and translates the packets back into appropriate voice or fax
signals.

1.2.1 Network Application

QSIG Network Interface

QSIG is a protocol based on ISDN (Q.931) that offers enhanced PBX features in a private network.
The QSIG network supports private communications by the TIE line service method. Implementation
of VoIP Gateway Cards provides a VoIP interface to employ a QSIG network between PBXs at
different locations by using an IP network instead of conventional telephone networks.

Types of IP Network

The V oIP Gatew ay Card's quality o f performance depends on the t ype of IP network in use. Manage d
IP networks provide better quality of service compared to unmanaged networks, wher e quality of
service is not guaranteed.

Examples of recommended IP networks

• Digital Leased Line

• IP-VPN (Virtual Private Network)

•Frame Relay

Notice

The performance of the VoIP Gateway Card may deteriorate when it is used on the Internet.
Delays and loss in data transmission can degrade speech quality, and impair the card's capability
to use the enhanced networking features of the PBX (for more inf ormation about these features,
refer to the relevant sections of the Hybrid IP-PBX documentation.)

Using the KX-TDA3480/KX-TDA0484 with Other KX-TDA Series VoIP
Gateway Cards

When using the KX-TDA348 0/KX-TDA0484 in a network that contains other KX-TDA series VoIP
Gateway Cards, keep in mind the following points:

1. Making and Receiving Calls

Calls can be made and received between the KX-TDA3480/KX-TDA0484 and other KX-TDA
series VoIP Gateway Cards. However, the KX-TDA0480 requires a special setting to be able to
communicate with the KX-TDA3480/KX-TDA0484 on the network. Refer to "D1 Considerations
in Installation" for more details.

2. Using QSIG Services

All QSIG services available with the PBX can be used between the KX-TD A3480/KX-TDA0484
and KX-TDA0490. However, CLIP service is the only available QSIG service between the KX­TDA3480/KX-TDA0484 and KX-TDA0480.

Firewall

A firewall protects the internal networks of an organisation against unauthorised penetration from
outside. When routing a VoIP network through a firewall, some perf ormance degradation may result.
If for practical reasons you must route the VoIP network through a firewall, refer to "A1.3 Network
Devices" for more details.

1.2.2 Numbering Plan Example

There are 2 methods to plan your numbering system, as follows:

In addition to the destination number , the caller dials the unique PBX code of the

PBX code
method

Extension
number method

This section provides a network numbering mechanism using the PBX code method based on the
previous example diagram. Configure your network referring to this example.

Note

An example using the extension number method is provided in "B Alternative Numbering Plan
Example".

PBX to which the called party is connected. Therefore, extension numbers at
separate PBXs in the network can overlap. For example, each PBX in the
network can have an extension whose number is 201.

The caller dials only the destination number of the called party to call through
PBXs at different locations (hence there are fe wer digits to dial than with the PBX
code method). To employ the extension number method, no 2 PBXs can have
extensions sharing the same number. For example, if one PBX in the network
has an extension whose number is 201, no other PBX can have an extension
with the same number (201).

4.2.5 Programming the Address Translation Table

The function of an address translation table in a VoIP network is to provide 2-way tra nslation of
telephone numbers and IP addresses
Gateway Cards in the network. Therefore, whenever the address translation table is changed, it is
important to update all the cards in the network with the latest information; othe rwise VoIP
communications cannot be established.

It is possible, at one location in the network, to prog ramme the address tr anslation tabl e that contains
information for the ent ire network. The completed address translation table can then be distributed
across the network, so that all the cards share the same information (see "4.2.6 Downloading the
Address Translation Table from the VoIP Gateway Card", and "Uploading Address Translation Table
to the VoIP Gateway Card" in "4.3 Programming the VoIP Gatewa y Card in the Chicago Office").

Note

The address translation table created for the KX-TDA0484 or KX-TDA3480 can be shared with
the KX-TDA0490.

The procedure below demonstrates the process of programming the address translation table
necessary for VoIP communications between the Los Angeles and Chicago offices.

The specific setting values are based on the table under "PBX Connection Information" in "1.2.2
Numbering Plan Example" .

A1.1 Bandwidth Assessment

When using the VoIP Gateway Card, you must ensure that the IP network in use has enough
bandwidth to support VoIP communications. If the amount of bandwidth required for VoIP
communications is larger than what the network can accommodate, speech quality will be
compromised. In addition, there ma y be some adverse eff ect on the performance of other applicati ons
(e.g., email or web applications) that use the same network. Therefore, care must be taken when
assessing bandwidth requirements.

Inform your network administrator of the required bandwidth, and make sure that the network can
support VoIP communications even under conditions of maximum network traffic.

Bandwidth Calculation

Provided below is the f ormula to find o ut the amount of bandwidth required f or VoIP communications:

Required Bandwidth

= (No. of Fax Machines × Required Bandwidth for Fax Communication) +
[(4 - No. of Fax Machines) × Required Bandwidth for Voice Communication]

Required bandwidth for fax and voice communications for one VoIP channel is shown in the tables
below (for more details, refer to "2.2.3 V oice Communication Par ameters" in the VoIP Gateway Card
Programming Guide).

Required Bandwidth for Voice Communication

The required bandwidth depends on what combination of CODEC and packet sending interval is
used. Keep in mind the following points about the type of CODEC and packet sending interval, in
terms of the speech quality:

• The speech quality of the CODECs varies as follows: (High) G.711, G.729A, G.723.1 (Low )

• The shorter the packet sending interval, the higher the speech quality.

• The higher the speech quality the VoIP Gateway Card provides, the more bandwidth the
card requires.

Consider the following case as an example:

• Communication: via LAN

• No. of Fax Machines: 1

• G.711 Packet Sending Interval for Fax Communication (not using the FAX High Reliable
Method): 40 ms (requiring 75.6 kbps per channel)

• G.729A Packet Sending Interval for Voice Communication: 30 ms (requiring 23.5 kbps per
channel)

In this case, the required bandwidth will be as follows:

Required Bandwidth

= (1 × 75.6) + [(4 - 1) × 23.5]
= 146.1

Therefore, inform your network administrator and make sure that the network can support a
bandwidth of 146.1 kbps even when the network is under conditions of maximum traffic.

Note

It is recommended that all cards in a VoIP network have the same packet sending interval.

A1 VoIP Requirements

A1.2 Network Configuration

You must evaluate the structure of the e xisting network to see if a VoIP network can be implemented.
Below are the points that should be taken into your evaluation.

Is it possible to have static IP addressing?

Because the maintenance of the VoIP Gateway Card is carried out from a personal computer (PC)
through an IP network, the card must be assigned a static IP address.

Static IP addressing must be made possible e v en when the DHCP feature is used. For more details,
refer to "2.2.1 Network Parameters" in the VoIP Gateway Card Programming Guide.

Is network address translation (NAT/NAPT) disabled?

In a network where address translation tech niq ue s (e.g., NAT/NAPT) are used to conver t bet ween
global and local IP addresses, VoIP communications based on the H.323 protocol cannot be carried
out appropriately. Generally, NA T/NAPT are features that are available with routers.

IP Network

Global IP Address Domain

(NAT/NAPT enabled)

If the router on the network supports the "H.323 NAT" feature, it may be possible to have VoIP
communications over the network. For more information, consult your network administrator.

A1 VoIP Requirements

Does only a single router provide access to the IP network?

In a dual network, 2 routers provide access to the IP netw ork as shown in the diagram below.
However, the VoIP Gateway Card cannot tak e the advantage of having 2 routers as access point s to
the IP network.

For exam ple, if router A, whose IP address is assigned as the def ault gate wa y IP address of the card,
fails, VoIP communications are no longer possible; the card is not able to switch its default gateway
from router A to router B to access the IP netwo rk. For more details about the def ault gatew ay setting,
refer to "2.2.1 Network Parameters" of the VoIP Gateway Card Programming Guide.

Is there only a single IP network between 2 ends of a call?

A huge degradation in speech quality will be produced when calls are made through multiple IP
networks as shown below; therefore, it is recommended that you avoid establishing a VoIP network
in this fashion.

Is the card located appropriately?

Transmission delays can cause pauses and loss in V oIP comm unications. The more netw ork devices
(e.g., routers and s witches) there ar e betwee n the communicat ing cards , the larger the transmission
delays, be cause a certain amount of delay is inevitab le when packets go thr ough each network device
(hop).

One preventative measure is to install the card so that the number of transmission hops is kept to a
minimum. In the diagram below, the card is located as close to the IP network interface as possible.

Are layer 2 or higher switches used?

Use of repeater hubs can increase the network load, and th erefore will result in degr adation in speech
quality.

To ensure high speech quality, it is strongly recommended that you use layer 2 or higher switches.

Are Category 5 (CAT5) cables used?

When connecting network de vices, make sure to use CAT5 cables. If other types of cabl es are used,
communications may not be carried out normally.

A1.4 QoS (Quality of Service)

Some routers permit the configuration of priority control f eatures. This allo ws the router to give h igher
priority to voice packe ts and low er the ra te of loss and d ela ys during transmissions , hence impr oving
speech quality. It is strongly recommended that you use this feature, especially in networks where
traffic is heavy.

Typically, a router identifies what packets to pass in priority by checking the value in the ToS field of
the header of IP packets. The VoIP Gateway Card has the ability to set the ToS field of outgoing voice
packets (see "2.2.3 Voice Communication Parameters" in the VoIP Gateway Card Programming
Guide). When the card is appropriately configured, the router can give voice packets from the card
higher priority.

Consult your network administrator when setting the ToS field, as the setting value must conform to
the router's specifications.

Note

Some switches also permit the configuration of priority control features. For more information,
consult your network administrator.

Card in the network during VoIP
communications. A unique IP address m ust be
assigned to each card.

Identifies the IP address of the primary gateway
(typically a router or similar device) that
exchanges IP packets with the other gateways
on the VoIP network.

Defines which digits of an IP address are used
for the netw ork address and the host address at
each network location. A card IP address must
fall within the same subnet as that of the default
gateway (e.g., router) that is connected to the
card.

DHCP Server

When using the DHCP feature, the IP address settings of the card (IP address, subnet mask, and
default gatewa y) will be assigned by a DHCP server.

However, k eep in mind that the maintenance of the card is performed through a web browser from a
PC; hence you must know the IP address of the card. Therefore, it is necessary to set up the DHCP
server to assign a static IP address to the card from a pool of IP addresses that is defined in advance.
For more information about DHCP server settings, consult your network administrator.

In addition, it is also necessary to specify the values for the parameters under IP Address Settings
as they will be assigned by the DHCP server.

When the primary gatekeeper fails, these checks can detect
the failure. In this case, the connection automatically switches
to the secondary gatekeeper if it is available, so that the
network remains functional.

Call Signaling Model

Specifies whether to carry out a call control (H.225) process
directly between the cards or through a gatekeeper.

Direct call control is typically preferred because it involves
less network load.

Detailed Explanations

Gatekeeper

The following are the general functions of a gatekeeper:

• Dialled number-to-IP address translation

• Authentication

• Bandwidth control

It is possible to employ a VoIP network without the use of a gatekeeper , because the card is equipped
with internal address translation capabilities. However, should the network contain dozens of cards,
maintenance of address translation tables in individual cards can become a strain.

A gatekeeper is useful in this case, because with the gatekeeper it is possible to consolidate the
maintenance. (However, you still need to programme each card on the network with its own address
translation information. For details, refer to "2.2.6 Address Translation Table—GW Entry" and "2.2.7
Address T ranslation T able—DN2IP Entry".) For more information about gatekeeper functions, consult
the documentation of the gatekeeper.

When using a gatekeeper, make sure to choose a compatible model. For more information about
gatekeeper compatibility with the card, consult a certified dealer.

Jitter buff er Settings

When voice signals are packetised and transmitted, individual packets can take different paths through the
network and arrive at the destination at varied timings. This is referred to as "jitter", and it can cause
degradation in speech quality. To compensate for jitter problems, the "jitter buffer" accumulates the packets
temporarily for processing.

The parameters below are used to adjust the size of the jitter buffer. However, in general, there is no need to
change the default values.

Echo Canceller

Specifies the use of the echo cancellation feature (G.168).
Echo is the audible duplication of a caller's voice on the return

path; when echo exists, the caller hears his or her own voice
after some delay. The echo canceller eliminates this echo.

Note

There are various factors that may cause an echo. In
some cases, this feature does not eliminate the echo
entirely.

G.723.1 VAD (Voice Activity Detection)

Specifies the use of the VAD feature (G.723.1).
The VAD conserves bandwidth by detecting silent periods

during a call and suppressing the packets of silence from
being sent to the network.
