VoIP { Voice Over IP }

What is VoIP? The transportation of packets containing voice data over a network (LAN, WAN or internet).

Why is it Important? • Voice over IP does not just mean “voice.” • Video, data conferencing • Cost • Convergence • Using high-speed internet connection for all voice, video, and data communications. • Reduce maintenance costs • Reduce deployments costs • Home has more options in service choices • Increased functionality

Better Use of Resources { Beating a Dead Horse }

How Does it Work? • Sound heard by computer at rate of 8,000 times per second or more • Uses CODEC (ulaw, alaw, gsm, ILBC, and others) • Speech CODECs are optimized to improve spoken words at the expense of sounds outside the frequency range of human speech • Placed into data packets – a single packet will contain 10 or more milliseconds (20 or 30 is more common) • PLC (Packet Loss Concealment) compensated for by CODEC • Redundancy • FEC (Forward Error Correction) • Delay • Jitter

How Does it Work?

The Wireless Version VOWi-Fi

PSTN = Public Switched Telephone Networks IMS = IP Multimedia Subsystem

A Blip about SIP{I’m so clever}

SIP { Session Initiation Protocol } • Simple • SIP has only six methods • Transport-independent (application-layer): • Can be used with UDP, TCP, and more. • Readable • text based

SIP { Session Initiation Protocol } Provides necessary protocol mechanisms so that end systems and proxy servers can provide services • call forwarding, including • equivalent to 700, 800, and 900 type calls • address-translation services • number delivery, where numbers can have naming scheme • personal mobility • the ability to reach a party under a single, location-independent address when the user changes terminals • negotiation • caller can be given choice how to reach the party • Internet telephony, mobile phone, answering service • caller and called authentication • invitations to multicast conferences

Can be stateful or stateless Proxy Server Redirect Hybrid Proxy Is Best Alternative

Stateful Proxy Servers • Maintains call context • Replicates User Agent Server/User Agent Client to process requests/responses • Call state and transaction state can be maintained • Forking proxies require state • TCP proxies must be stateful for reliability • Enhanced services require state for execution • Can populate billing information Services Dictate Statefulness of Proxy

Stateless Proxy Servers • No call context • Response is not based on User Agent replication • Provides client anonymity • Restricted gateway access • High processing capacity • Allows for easier replication than stateful proxy • Can have semi-stateful proxy for ultimate benefits Stateless Proxies Geared for Capacity

Can be stateful or stateless Proxy Server Redirect • High capacity • Flexible, network service implemenations • Minimal state overhead • Service execution pushed to client • Reliability achieved through replication • Scalability achieved through partitioning • Overload potential if not properly scaled • Hybrid (semi-stateful) model provides maximum benefits Hybrid Proxy Is Best Alternative

H.323 • Complex • Easier to look at H.323 and SIP comparisons than to try to understand ‘how it works’ in a brief period of time • (big debate)

What does that mean?! • Scalability: SIP • Reliability: H.323 • Speed: SIP • Standardized: H.323 • Most Flexibility with Services: SIP • Low Complexity: SIP • Features (as of right now): H.323 Everyone is biased!

Commercial Break{please stay tuned for your regularly scheduled broadcasting

Some Problems • Reliability • Quality • Example: NATs prove to be big problem

STUN { Simple Traversal of UDP through NAT } • Used in residential NATs • allows for P2P connection through the NAT • Not 100% reliable • Does not work with Enterprise NATs (Symmetric)

TURN { Traversal Using Relay NAT } • Uses relay server to connect to single peer behind the NAT • 100% Reliable • Comes at great cost • Access bandwidth • Delay

ICE { Interactive Connectivity Establishment } • Basically says to use STUN if at all possible, only using TURN as a last resort.

one smart decision amongmany many stupid ones Please stay tuned for the conclusion of your program, just after this

Problems with VoIP • Bandwidth Dependency • No internet = no phone • Poor connection = hate • Shared connection = unpredictable • Power Dependency • No power = no router/modem/ATA = no phone • No power = no 911 • Voice Quality • Delays, noise, echoes, strange sounds • Less robust than PSTN • Milliseconds mean everything

Security Problems • Phreaking • Encryption is not common in SIP • Eavesdropping • Viruses and Malware • Soft-phones • DOS (Denial of Service) • SPIT (Spamming over Internet Telephony) • Easy to send to thousands of IP addresses (leads to phishing) • Call Tampering • Man-In-the-Middle Attacks • Particularly vulnerable

Recent Legal News • Patents • Verizon won $58 million patent suit against Vonage • Web Telephony filed patent lawsuit with Verizon, Vonage, AT&T, EarthLink, and SunRocket • DoT clamp down in India • unlicensed foreign service providers

In Conclusion, why use VoIP? Because even Jack Bauer Needs it

Nowadays, Multimedia Communication has been developed and improved rapidly in order to enable users to communicate between each other over the Internet. In general, the multimedia communication consists of audio, video and instant messages communication. This paper surveys the functions and the privileges of different voice over Internet protocols (VoIP), such as InterAsterisk eXchange Protocol (IAX), Session Initiation Protocol (SIP), and H.323 protocol. As well as, this paper will make some comparisons among them in terms of signaling messages, codec’s, transport protocols, and media transport, etc. https://sites.google.com/site/ijcsis/

This paper analyzes the future evolution paths of voice communications services. The focus is on defining the role and success potential of different types of VoIP services, ranging from IM-like do-it-yourself VoIP to operator-managed VoIP services with QoS guarantees and PSTN interconnectivity. The paper proposes a simple model for voice service classification, and analyzes the end-user value and market potential of different VoIP services classes. The concepts of network effects and disruptive technologies form the framework for analyzing the evolution paths of voice communications from circuit-switched networks to VoIP services. Substitution effects between fixed, wireless, and mobile domains are recognized as an important factor affecting the success potential of VoIP services. Based on the discussion, some remarks are made regarding the QoS and pricing issues of different types of VoIP services.
