What is MAC Cloning?

MAC cloning means to configure new MAC address [MAC-2] for the host without changing existing MAC address [MAC-1]

After doing MAC cloning host sends newly configured MAC address [MAC-2] in Ethernet Frames in place of sending

existing MAC address [MAC-1]

How MAC Cloning works ?

ISP Is Authenticating Host With MAC Address

ISP

Cloned MAC:- 01:1d:1a:02:82:34

Fix MAC:- 02:2d:1c:02:32:45

Why MAC Cloning?

Many times ISP tracks MAC address of host installed at customer premise to authenticate him as valid customer to provide Internet service

Due to this reason customer can access Internet only from single Host

Configuration of MAC Cloning


Select the internet Connection Type here Options: - Static

- PPPoE - DHCP

If the selected internet Connection Type is

‘PPPoE’,program the User ID, Password and PPPoE service

name here


If “Static” option is selected for DNS Address Assignment, then program the IP address of DNS and Domain

Name here

Select the DNS Address Assignment option here

(Auto/Static). If the selected option is ‘Auto’ then there is no need to

program the DNS address. It will be automatically assigned by the Service Provider/DHCP server

What is Dynamic DNS?

Dynamic DNS means assigning a Domain Name to such host whose IP address changes frequently

Due to facility of DDNS that host can always be accessible from WAN by using same Domain Name

Why Dynamic DNS?

ISP

DHCP Connection

What is system’s

present IP?

1st attempt: 116.72.127.98

2nd attempt: 117.89.97.123

3rd attempt : 115.161.181.183

4th attempt: 118.187.24.89

Why Dynamic DNS?

In this case host will not be accessible always using public IP assigned to it by ISP

When ISP gives Internet connection type as PPPoE or DHCP then IP assigned to router at client site may be changed frequently

It can be resolved by using Dynamic DNS

How DDNS works?

DDNS Server is accessible globally, it keeps details of domain name

and global IP of all customers

DDNS Client Which Gives Update To Server

About Global IP Of Router

Dynamic DNS Configuration

Enable/Disable Dynamic DNS here. Enabling this option will help the VoIP

card to inform the SIP clients to pass the information of latest IP assigned to the VoIP card by the DHCP or PPPoE Server

Turn ON this option if the internet Connection type is DHCP or PPPoE

and DDNS option is enabled

DDNS option will be useful only if the Internet Connection Type is DHCP or PPPoE


Program the ‘Password’ provided by Dyndns.org

here, if the DDNS option is enabled

Program the ‘User-ID’

provided by Dyndns.org here, if the

DDNS option is enabled

Program the Host Name provided by Dyndns.org

here, if the DDNS option is enabled


Number of request send by the VoIP Card to DDNS

Server for the IP update request. Applicable only if

DDNS is enabled

This option helps the VoIP Card to re-establish the

mapping with the DDNS if the IP update request has not been sent in time by

the VoIP Card


It shows that VoIP card has successfully sent request to DDNS

server to update router’s public IP

detail in database of DDNS server


It shows that VoIP card failed to send request to DDNS server to update

router’s public IP

With this option when user will send SIP messages then VoIP card will listen for SIP message which is

redirected to programmed Domain Name and WAN IP Address

VoIP Server Domain

If client already have fix Domain name purchased from DNS service provider then that DNS can be configured here

That DNS will be assigned to VoIP server card

All SIP users from WAN can register to this DNS assigned to IP server card

Mostly public IP mapped to this Domain remains fixed that make it different from DDNS

SIP Trunk



SIP Trunk Configuration

VoIP calls can be initiated after suitable programming of SIP Trunks

ETERNITY supports 2 types of SIP trunks: Peer to Peer and Proxy

Peer-to-Peer Calling

203.88.143.218 204.88.142.218

Internet TCP/IP

Making a VoIP call directly to the destination without any intervention of any mediator is called

peer-to-peer calling.

You just need to know the called party’s IP address.



Select Peer-To-Peer in the SIP Trunk Mode You can select either

Trunk or Station

If you select Trunk, then it will follow the

Trunk Feature Template as per the

SIP trunk

Configuration: Peer-to-Peer Calling


If you select Station, then it will follow the direct landing on specified

extension

Calling 205

201 205 207

Proxy Calling

Making VoIP calls through proxy server is called proxy calling

Proxy Server: abc.com

Client 2 SIP ID 402

Client 3 SIP ID 403

401 calling 402

Client 1 SIP ID 401

Requirement for Proxy Calling

Proxy server authenticates the clients for outgoing calls through it

What is required for

authentication?

SIP ID

Authentication ID


Registrar Server Address

Proxy Calling

Program SIP ID here as per given by ITSP Program Registrar Server

address here. To be obtained from ITSP

Program Registrar Server port here. To be obtained from ITSP

(1025-65535)

Proxy Calling

It is the timer after which

request has been sent again

Registration retry if registration request is not acknowledged

User ID & password given by ITSP for authentication

Proxy Calling

Enable outbound proxy from here

Enter outbound proxy sever address here

Enter outbound proxy sever port here

Proxy Calling

Define SIP hardware

template here

Define TFT here if the SIP Trunk entity is “SIP

Client”

SIP Trunk Properties

Define Cost Factor here

Used in Gateway Application (01-64)

Enable RCOC here

SBFT, SAFT are applicable on the SIP Trunk if the SIP Trunk entity is P2P


By enabling these flags you can authenticate SIP user during

these different request messages


Enable if you want to send CLI on SIP trunk

Enable if you want to accept IC calls without

CLI


Define Source port IP address here

Enable/disable Digest Authentication

Enable Symmetric RTP from here

Why Symmetric RTP?

Symmetric RTP can be used in firewalls, debugging and troubleshooting.

Generally it is useful to resolve bidirectional speech problems.

Many firewalls, NATs, RTP implementations don’t work on asymmetric RTP but require symmetric RTP.

Digest Authentication

It is a security feature which is used by VoIP card during peer to peer incoming call

On any incoming SIP call, VoIP card will check the authenticity of the SIP user by Authentication ID and Password

This authentication is done by using Digest Authentication Table

If authentication doesn’t match, VoIP card will reject the incoming SIP call


SIP users configured with following User ID and Password will only be allowed to access ETERNITY during

Peer To Peer calling


Enable this flag in SIP Trunk

parameters


Select default transport for outgoing messages i.e. UDP, TCP

or TLS

UDP v/s TCP v/s TLS

UDP TCP TLS

UDP is connectionless and acknowledgement less protocol (DNS, VOIP)

TCP is connection oriented & provides acknowledgement (WWW, FTP, E-mail)

TLS is connection oriented protocol & provides acknowledgement

Used for time sensitive applications

TCP requires more bandwidth than UDP

TLS requires more bandwidth than TCP

Used for servers that answer small queries from huge number f clients

Used in the applications where secure connection is required & data loss should be less

When secure transportation is to be used


Define IC ref. ID & OG ref. ID here for DDI mapping

Program the value of

pause timer here (1-9)


Used during Gateway Application


This is set as per the requirement of

By enabling this flag Silent RTP packets will not be sent during conversation

Used for efficient usage of available

bandwidth


TX and RX speech level can be changed from here



Select DTMF type from following options

- RTP (RFC 2833) - SIP Info - In band

Same DTMF option must be configured in SIP user device

If RTP(RFC 2833) is

selected then this should be

configured


By enabling this flag Echo Cancellation will be activated when SIP users are talking to

Stations/Trunks [Analog/Digital]

This parameters can be configured according to strength of Echo required to

be cancelled

Separate options available for analog

and digital interfaces

Jitter Buffer

By considering packet network jitter can be defined as variation of delay in receiving packets

To resolve this problem the mechanism used in VoIP device is called “Jitter Buffer”

VoIP device stores packets according to Jitter Buffer timer supported by it to maintain common delay between successive packets before processing them

for regeneration of voice


Select “Static” option for network having precise delay but when delay is

not fixed always from network side then select option “Dynamic” Configure Jitter Buffer

timer here

Configure it for Dynamic Jitter Buffer

option


Select Protocol for FAX over IP. Following are options:

- T.38 (UDPTL) - T.38 (RTP)

- Pass Through

FAX Parameters is customized when protocol is selected as T.38


FAX Parameters customization when protocol selected as Pass Through

White List IP Address

ETERNITY supports security on Transport Layer

By enabling this security option ETERNITY VoIP card will accept incoming

traffic only from those VoIP devices whose IP address is configured in White List Table

White List IP Address

Configure here, IP Addresses of devices from where you want to receive incoming call traffic on VoIP card

Enable this flag to use IP level security

Static Routing

Some times customer have multiple routers in their network to connect their multiple sites using MPLS (Multiprotocol Label Switching)/ Frame Relay

In same network there can be distinct routers to connect to Internet

In such network scenario to connect VoIP devices at multiple sites using point to point connectivity there is need of some mechanism to route the calls from different

router according to IP address of different destination VoIP devices
