Future enhancements discussed include integrating VoIP with wireless networks.
VLAN Trunking Protocol (VTP) is a Cisco proprietary protocol that propagates the definition of Virtual
Local Area Networks (VLAN) on the whole local area network.[1] To do this, VTP carries VLAN
information to all the switches in a VTP domain. VTP advertisements can be sent over ISL, 802.1Q, IEEE
802.10 and LANE trunks. VTP is available on most of the Cisco Catalyst Family products.
This chapter will cover how to configure, manage, and troubleshoot VLANs and
VLAN trunks. It will also examine security considerations and strategies relating
to VLANs and trunks, and best practices for VLAN design.

VRRP (Virtual Router Redundancy Protocol) is a computer networking protocol that provides for
automatic assignment of available Internet Protocol (IP) routers to participating hosts. This increases the
availability and reliability of routing paths via automatic default gateway selections on an IP subnetwork.
The Virtual Router Redundancy Protocol (VRRP) eliminates the single point of failure inherent in the
static default routed environment. VRRP specifies an election protocol that dynamically assigns
responsibility for a virtual router (a VPN 3000 Series Concentrator cluster) to one of the VPN
Concentrators on a LAN. The VRRP VPN Concentrator that controls the IP address(es) associated with a
virtual router is called the Master, and forwards packets sent to those IP addresses.
Voice over Internet Protocol (Voice over IP, VoIP and IP telephony) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).The steps and principals involved in originating VoIP telephone calls are similar to traditional digital telephony and involve signaling, channel setup, digitization of the analog voice signals, and encoding.

1) Describe the three primary options for enabling inter-VLAN routing.
2) Configure legacy inter-VLAN routing.
3) Configure router-on-a-stick inter-VLAN routing.
4) Troubleshoot common inter-VLAN configuration issues.
5) Troubleshoot common IP addressing issues in an inter-VLAN-routed environment.
6) Configure inter-VLAN routing using Layer 3 switching.
7) Troubleshoot inter-VLAN routing in a Layer 3-switched environment.
Inter-VLAN routing is the process of forwarding network traffic from one VLAN to another VLAN using a
router.
VLANs divide broadcast domains in a LAN environment. Whenever hosts in one VLAN need to
communicate with hosts in another VLAN, the traffic must be routed between them. This is known as
inter-VLAN routing. On Catalyst switches it is accomplished by creating Layer 3 interfaces (Switch virtual
interfaces (SVI)).

VoIP (Voice over Internet Protocol).pdfOkan YILDIZ
VoIP (Voice over Internet Protocol) transmits voice and multimedia content over an internet connection. VoIP allows users to make voice calls from a computer, smartphone, other mobile devices, special VoIP phones and WebRTC-enabled browsers. VoIP is a valuable technology for consumers and businesses, as it typically includes additional features that can't be found on standard phone services. These features include call recording, custom caller ID, and voicemail to e-mail. It is also helpful to organizations as a way to unify communications.
The process works similarly to a regular phone, but VoIP uses an internet connection instead of a telephone company's wiring. VoIP is enabled by a group of technologies and methodologies to deliver voice communications over the internet, including enterprise local area networks or wide area networks.
A VoIP service will convert a user's voice from audio signals to digital data and then send that data through the internet. If another user calls from a regular phone number, the signal is converted back to a telephone signal before reaching that user.
VoIP can also route incoming and outgoing calls through existing telephone networks. However, some VoIP services may only work over a computer or VoIP phone.
A NEW SYSTEM ON CHIP RECONFIGURABLE GATEWAY ARCHITECTURE FOR VOICE OVER INTER...csandit
The aim of this paper is to present a new System on Chip (SoC) reconfigurable gateway
architecture for Voice over Internet Telephony (VOIP). Our motivation behind this work is
justified by the following arguments: most of VOIP solutions proposed in the market are based
on the use of a general purpose processor and a DSP circuit. In these solutions, the use of the
serial multiply accumulate circuit is very limiting for the signal processing. Also, in embedded
VOIP based DSP applications, the DSP works without MMU (memory management unit). This
is a serious limitation because VOIP solutions are multi-task based. In order to overcome these
problems, we propose a new VOIP gateway architecture built around the OpenRisc-1200-V3
processor. This last one integrates a DSP circuit as well as a MMU. The hardware architecture
is mapped into the VIRTEX-5 FPGA device. We propose a design methodology based on the
design for reuse and design with reuse concepts. We demonstrate that the proposed SoC
architecture is reconfigurable, scalable and the final RTL code can be reused for any FPGA or
ASIC technology. Performances measures, in the VIRTEX-5 FPGA device family, show that the
SOC-gateway architecture occupies 52% of the FPGA in term of slice LUT, 42% of IOBs, 60%
of bloc memory, 8% of integrated DSP, 16% of PLL and the total power is estimated at
4.3Watts.

Voice over Internet Protocol with Novel Applicationsirjes
Internet Telephony, often denoted as Voice-over-Internet-Protocol (VoIP), has gained more and
more attention world-wide during the last decades. Voice over Internet Protocol (VoIP) technology has become
a communication alternative with the continuous increasing of Internet bandwidth and rapid advancement of
peer-to-peer (P2P) applications.In this paper three types of VOIP are explained: (i) PC to PC : this is the easiest
way to use VOIP, which enables you to talk and communicate Voice over Internet with all people over the
world. (ii) PC to Phone: which need a gateway that connects IP Network to phone Network. Its uses a device
called an ATA (Analogue Telephone Adaptor).The ATA allows you to connect a standard phone to your
computer or your Internet connection for use with VOIP. The ATA is an analogue to digital converter. (iii)
Phone to Phone: Where you need more gateways that connect IP network to phone networks, more phone
networks that connect Telephone set to gateway, and IP network that connect gateway to gateway. This paper
also explains Internet Protocol (IP) that VOIP uses to transmit voice as packets over an IP network as follows:
H.323 Protocols that provides the technical requirements for voice communication over LANs, while assuming
that Quality of Service isn't provided by LANs. Session Initiation Protocol (SIP) standard which is the standard
for establishing VOIP connections. This paper also explores Voice XML which is a markup language derived
from XML for writing telephone-based speech applications.In this paper also VoiceXML developed
environments(Gateways) are explained, where a list of all VoiceXML developers is included, and the most
popular VoiceXML development environments (Gateways) are explained in details.Finally, in this paper ten
VoiceXML applications are developed

2. Project on VOIP
1.1 Introduction to VOIP
Voice over Internet Protocol (VoIP) is a methodology and group of technologies for the
delivery of voice communications and multimedia sessions over Internet Protocol (IP)
Networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony,
Internet telephony, voice over broadband (Dobb), broadband telephony, IP communications,
and broadband phone service.
The term Internet telephony specifically refers to the provisioning of communications services
(voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched
telephone network (PSTN). The steps and principles involved in originating VoIP telephone
calls are similar to traditional digital telephony and involve signaling, channel setup,
Digitization of the analog voice signals, and encoding. Instead of being transmitted over a
circuit-switched network, however, the digital information is packetized, and transmission
occurs as Internet Protocol(IP) packets over a packet- switched network. Such transmission
entails careful considerations about resource management different from time-division
multiplexing (TDM) networks.
Early providers of voice over IP services offered business models and technical solutions that
mirrored the architecture of the legacy telephone network. Second-generation providers,
such as Skype, have built closed networks for private user bases, offering the benefit of free
calls and convenience while potentially charging for access to other communication networks,
such as the PSTN. This has limited the freedom of users to mix-and-match third-party hardware
and software. Third-generation providers, such as Google Talk, have adopted the concept of
federated VoIP—which is a departure from the architecture of the legacy networks. These
solutions typically allow dynamic interconnection between users on any two domains on the
Internet when a user wishes to place a call.
Useful Terms
Understanding the terms is a first step toward learning the potential of this technology:
VoIP refers to a way to carry phone calls over an IP data network, whether on the
Internet or your own internal network. A primary attraction of VoIP is its ability to help
reduce expenses because telephone calls travel over the data network rather than the
phone company's network.
IP telephony encompasses the full suite of VoIP enabled services including the
interconnection of phones for communications; related services such as billing and
dialing plans; and basic features such as conferencing, transfer, forward, and hold.
These services might previously have been provided by a PBX.
3. IP communications includes business applications that enhance communications to
enable features such as unified messaging, integrated contact centers, and rich-media
conferencing with voice, data, and video.
Unified communication stakes IP communications a step further by using such
technologies as Session Initiation Protocol (SIP) and presence along with mobility
solutions to unify and simply all forms of communications, independent of location,
time, or device. (Learn more about unified communications.)
VoIP systems employ session control and signaling protocols to control the signaling, set-up,
and tear-down of calls. They transport audio streams over IP networks using special media
delivery protocols that encode voice, audio, video with audio codecs, and video codecs as
Digital audio by streaming media. Various codec exist that optimize the media stream based
on application requirements and network bandwidth; some implementations rely on
narrowband and compressed speech, while others support high fidelity stereo codecs. Some
popular codecs include μ-law and a-law versions of G.711, G.722, which is a high-fidelity
codec marketed as HD Voice by Polycot, a popular open source voice codec known as LBC, a
codec that only uses 8 Kbit/s each way called G.729, and many others.
VoIP is available on many smart phones, personal computers, and on Internet access devices.
Calls and SMS text messages may be sent over 3Gor Wi-Fi

5. 1.4 IP Phones
A IP phone uses voice over IP (VoIP) technologies allowing telephone calls to be made over
an IP network such as the Internet instead of the ordinary PSTN system. Calls can traverse the
Internet, or a private IP network such as that of a company. The phones use control protocols
such as Session Initiation Protocol(SIP), Skinny Client Control Protocol(SCCP) or one of
various proprietary protocols such as that used bySkype. It is commonly refers to the
communication protocols, technologies and transmission techniques involved in the delivery
of voice communications and multimedia sessions over Internet Protocol (IP) networks, such
as the Internet.
Session Initiation Protocol (SIP) is a signaling protocol widely used [citation needed] for
controlling communication sessions such as voice and video calls over Internet Protocol (IP).
The protocol can be used for creating, modifying and terminating two-party (Uni-cast) or
multiparty (Multi-cast) sessions. Sessions may consist of one or several media streams.
6. Skinny Client Control Protocol (SCCP) is a
proprietary network terminal controlprotocol. SCCP
is a lightweight protocol for session signaling with
Cisco CallManager.
Examples of SCCP clients include the Cisco 7900
series of IP phones, Cisco IP Communicator
softphone along with Cisco Unity voicemail server.
CallManager acts as a signaling proxy for call events
initiated over other common protocols such as Session
Initiation Protocol (SIP), ISDN.A SCCP client uses
TCP/IP to communicate with one or more Call
Manager applications in a cluster. It uses the Real-
time Transport Protocol (RTP) over UDP-transport
for the bearer traffic (real-time audio stream).
Configuration of IP Phones
First you need to set the following topology ip phones / analog phones but connect phones to
power one by one after finishing configuration:
7. Next you will need to configure your switch with the following commands:
Switch(config)#interface range fa0/1 – 6
Switch(config-if-range)#switchport mode access
Switch(config-if-range)#switchport voice vlan 1
Then we need to configure our router to provide IP address to IP phones and set the calling
numbers for phones , we will use CME call manager express embedded with router IOS itself.
Router(config)#interface fa 0/0
Router(config-if)#ip add 10.0.0.1 255.0.0.0
Router(config-if)#no shut
Router(config-if)#exit
Router(config)#ip dhcp pool HCL
Router(dhcp-config)#network 10.0.0.0 255.0.0.0
Router(dhcp-config)#default-router 10.0.0.1
Router(dhcp-config)#option 150 ip 10.0.0.1
Router(dhcp-config)#exit
Router(config)#telephony-service
Router(config-telephony)#max-dn 10 ( max numbers on directory)
Router(config-telephony)#max-ephones 10 (max number of phones)
Router(config-telephony)#ip source-address 10.0.0.1 port 2000
Router(config-telephony)#auto assign 1 to 10

Router(config-ephone-dn)#number 104
8. Chapter 8. Future Enhancement
Voice over Internet Protocol (VoIP) is one of the hottest and most hyped technologies in the
communications industry. Businesses and consumers are already taking advantage of the cost
savings and new features of making calls over a converged voice-data network, and the logical
next step is to take those advantages to the wireless world. The most widely publicized benefit
of VoIP is the ability to save costs on long distance charges and to network multiple offices
together. Businesses that have a data connection between their offices can utilize VoIP
technology to bypass long distance networks and provide more efficient communications
between offices. In a traditional setting, someone would have to dial the phone number to a
branch office, possibly paying a long distance charge for the call, wait for a receptionist or
automated system to answer and then become connected to the party they’re trying to reach.
Using VoIP, a person can simply dial an extension number and be connected immediately to a
party in another office, whether across town or around the world avoiding costly long distance
charges.
A second benefit is in the design of many telephone systems, often called IP based
systems. Rather than traditional phone systems with their own wiring infrastructure, IP based
systems use a data network infrastructure. This convergence of voice and data into a single
platform has tremendous advantages in simplifying the administration of the communications
network. Plus, IP utilizes data infrastructure that most likely already exists in many companies.
A third benefit is the ability to have remote phones with a single telephone number. For
example, an employee could work out of their home in New York, utilizing a phone number
with a California area code. This enables corporations to truly take advantage of having a
virtual office and or remote agents working out of a variety of location
