10. Introduction to VoIP

11. What is VoIP?
Voice over Internet Protocol is a technique which is
used in delivery of voice communication sessions over
internet
In VoIP calling, voice is first converted into digital
signals or IP packets and then transferred over internet

12. VoIP Devices
IP Phones
ATA
The phone able
to connect itself
directly to the
internet for VoIP
communication
Connects a standard
phone to Internet for
VoIP communication.
The ATA is an Analog-

(Session Initiation Protocol)

16. What is SIP?
The Session Initiation Protocol (SIP) is an application layer/control (signaling)
protocol for creating, modifying and terminating sessions with one or more
participants
For
transportation,
SIP uses TCP UDP
OR
Protocol it
uses
SIP V2.0

17. SIP
RTP
SIP
Real-Time Transport Protocol
is used in SIP for real media
transfer (Voice, Video etc.)

18. SIP Messages
INVITE Indicates a client is being invited to participate in a call session.
ACK Confirms that the client has received a final response to an INVITE request
BYE Terminates a call and can be sent by either the caller or the callee.
CANCEL Cancels any pending request.
OPTIONS Queries the capabilities of servers.
REGISTER Registers the address listed in the to header field with a SIP server.
PRACK Provisional acknowledgement.
SUBSCRIBE Subscribes for an Event of Notification from the Notifier.
NOTIFY Notify the subscriber of a new Event.
PUBLISH publishes an event to the Server.

46. VoIP Port Configuration in ETERNITY
When the VoIP card is
installed in a Public IP
Network?
WAN Port of the card is connected to a
Broadband Router / Modem
Public IP is assigned to the WAN Port
LAN port is connected to a switch/hub to
which SIP devices are connected
When VoIP card is
installed in a Private N/W,
behind a NAT Router
WAN Port connected to the LAN Switch / Hub
Private IP is assigned to the WAN Port
SIP devices within the LAN can get registered
with the Card

49. WAN Port Configuration
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

50. WAN Port Configuration
When Connection Type : Static
Configure the 32 bit IP Address,
Subnet Mask & Gateway Address
as provided by the network
administrator or ISP

51. WAN Port Configuration
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

52. Dynamic DNS Configuration
Program the ‘User-ID’
‘Password’ 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
DDNS option will be useful only if the Internet
Connection Type is DHCP or PPPoE

53. Steps to configure the DynDNS
Open the
DynDNS
Server on
dyndns.org
Enter the Username & Password.
Create an account if you are
accessing it for the 1st time
*‘DYN DNS’ is trademark of Dynamic Network Services INC, USA

54. Steps to configure the DynDNS
Go to My Services -
Add Host Name

55. Steps to configure the DynDNS
Configure the
parameters for
a new Host
Name

56. Steps to configure the DynDNS
Select VoIP &

Router. If flag is
“Enabled” then
System will use the
SIP listening Port
information
provided by the
STUN Server
Program the STUN Server

63. Router’s Public IP Address
Port
Forwarding
Since STUN doesn’t work with symmetric NAT , as an alternative to STUN Port
Forwarding can be done in the router and Router’s Public address that is configured
can be used as Source Port IP Address

69. Some Concerns related to
SIP Extension and VoIP Channels
When SIP Extension makes a call to another SIP Extension a total of Two VoIP
Channels will be consumed
When a SIP Extension makes a call Using any other Trunk except SIP Trunk of the
System only one VoIP channel will be consumed
When a SIP Extension makes a OG call using a SIP Trunk of the System Two VoIP
Channels will be consumed
When a normal DKP/SLT Extension of a system make OG call using SIP Trunk of the
system only one VoIP channel will be consumed
