Introduction

Providing mobileenvironment for VoIPcalls

You can use SIPphones to call yourfriends and family atany geographicallocation

Provide low rate callsor even free calls.

Hi !

Hello..


4/27

LiteratureSurvey

For developing this project we have referred number of IEEE papersfor gaining better knowledge in this subject. Some of those papers

are as follows:

Call set-up time modeling for SIP-based stateless and

stateful calls in Next Generation Networks

Voice over Internet Protocol on Mobile Devices

Efficient User Controlled Inter-Domain SIP MobilityAuthentication, Registration, and Call Routing

What is IP Telephony?

Internet Telephony (Voice over IP) essentiallymeans a voice message transmitted using theInternet Protocol

Basically this means sending voice information indigital form in discrete packets as opposed to thetraditional circuit-committed protocols of the publicswitched telephone network.

PBX: Private Branch Exchangeis a telephonesystem within an enterprise that switches callsbetween enterprise users

What is SIP and Why SIP?

In the world of VoIP, SIP is a call setup protocol thatoperates at the application layer

SIP is the core protocol for initiating, managing andterminating sessions in the Internet

These sessions may be text, voice, video or a combination

of these

SIP sessions involve one or more participants and can use

unicast or multicast communication


9/27

SIP Entities

User Agent

User Agent Client (UAC)a client application that

initiatesSIP requests.

User Agent Server (UAS)

a server application thatcontactsthe user when a SIP request is received and

that returns a response on behalf of the user.

Proxy Server

Redirect Server

Registrar


10/27

SIPMessageThere are two types of SIP messages:

1]Request methods

REGISTER : Used by a client to register with a SIP server

INVITE : Initiates a call

ACK : Confirms a final response for INVITE

CANCEL : Used to cancel a pending request BYE : Terminates a call

OPTIONS : Used to query a server

2]Response code

1xx : searching, ringing 2xx : success

3xx : forwarding

4xx : client mistakes

5xx : server failures

6xx : busy, refuse, not available anywhere

SIP Flows Via ProxyThe SIP proxy only participates in the SIP user authentication and

messages, once the call is set up, the phones send their voice traffic

directly to each other without involving the proxy

miniSipServer

2) Programming Languages

Dot Net

3) Hardware Requirements

Processor: P4/Dual core RAM: 64MB

Hard Disk: 10 GB


15/27

MainModule

Basic Two Modules

Server Side - miniSIPserver for routingcalls

Client Side - For making calls andreceiving calls


16/27

Server Settings

The software works as a fully featured telephone switch connecting tophone lines and extensions using state-of-the-art VoIP technology.

Offering all the normal features of a traditional PBX

Works with Any Standard Soft Phone

Support static as well as dynamic IP


17/27

Add new usersThe procedure of adding new user to the network is

not a tedious job from this application.Thus provides,

Easy adding user

Easy to modify the current user

Easy deletion of existing user

19/27

Local User StatusAt the server side, it shows the status of the registered users.

Here the BLUE color icon shows the active users i.e.

users that are online at that instant.

.

Step 2]

For caller : Dial user number

Make call

Hang-up the call after

connection done

Line status :

Line1- Dialing /Trying, forestablishing the call

Line1-Ringing,indicating call got

established

Line1- Connected, indicates that

the call got connected with end

user

Line1-Busy,line is busy with other

end user on call

Line2-Free,this line can be use to

make or accept call.

.

.

Step 3]

For callee:

When the caller makes a call, on the callee side the

callee gets this window having the following

options:

Accept the call

Reject call


22/27

Advantages and Disadvantages

1) Advantage

Reduce long distance calling cost.

Free calls for SIP to SIP user agents.

Portable

Clear voice quality

2) Disadvantage This application is expensive to use

No facility to make Emergency Calls


23/27

Applications

Setting up a Private LAN in office

Voice Mail Service

Ringing Group Service

In VPN help to make call within the network


24/27

Future Scope

Compatibility with any mobile phones

Developing more APIs using SIP like

Virtual conference room service

Voice message

IP Billing


25/27

Conclusion.

Thus this application will help people to

communicate staying in any Geographical

location at low cost.
