This document summarizes a presentation on Voice over Internet Protocol (VoIP) technology. It discusses what VoIP is, the advantages it provides over traditional phone systems, and ways that VoIP can be implemented. It also addresses some challenges to adopting VoIP in India, such as insufficient bandwidth in some areas and lack of policies encouraging investment. The overall purpose is to explore how VoIP can offer a more cost-effective alternative to traditional phone networks.

4.  There are three popular ways to say it, with none
being a definitive "right" way. All are correct.
 Some people will use the full acronym,
pronouncing each letter "V-O-I-P".
 Some people will use the first two words
combined with IP (pronounced as separate letters).
This is actually more like a phrase "Voice-Over-I-
P".
 Some will say the acronym as a word, just as it
sounds (like void only with a p at the end) "voyp".

5.  Regarding the business VoIP market, in early
2006, Yankee Group predicted a compound
annual growth rate (CAGR) of 31.4 percent,
adding that the market would reach nearly $3.3
billion in 2010.
 According a report from BBC there is about
2.2trillion dollar VoIP market in India by 2012.

6.  Voice packets transported using IP
 Traditional networking infrastructure carries
voice traffic
 Standards based (e.g., H.323, G.711, G.729,
RTP, UDP, IP, RSVP)

7.  To make a low cost and efficient
communication system
 Better Utilization Of Bandwidth
 Keep track of the calls.

8.  Enhances the “office of the future”
 Mobility and integration of voice mail, electronic mail, FAX,
and video technologies
 Single network management system
 Simplifies moves, adds, and changes for phones
 Choice of phone power
 Flexible IP address assignment
 Increased system redundancy

deck Airbus A380, is
the worlds largest jet,
it uses Linux to run all
of this plane’s
instruments.
Who wouldn’t feel
safe using a phone
system that utilizes an
operating system just
like this?

10. These Systems are
proprietary. They each are
good with their own
strengths and weakness’s.
Then there is the “new best of Breed”

11. 1) Auto Attendant - Answer all calls
professionally, without the need for a
receptionist
2) Voicemail - Never full, Personal greetings,
Email Notifications
3) Call Routing - Follow-me calling, Virtual
extensions, Transfer calls to other extensions,
the operator, voicemail, or a queue
4) User Experience - Caller ID/preview, Call
screening, Do-not-disturb

12. 5) Record any call by pressing *1 (silently or
announced)
6) Conferencing - Conference-on-demand, Every
extension, Flexible security
7) Mail-only extensions - Play informational
messages or just take messages
8) Music jukebox - Choose different songs in a
variety of styles
9) Block calls to specific phone numbers,
exchanges or area codes

 PC to Phone
 Phone to PC

15.  Have to deal with packet loss, jitter, and delay
 Have to deal with the bandwidth issues in the
places which lack proper infrastructure.

18.  What are some of the differences?
 System administration
 Phone features

19.  Cisco PAP2 Adapter or any Analog to digital
voice converter
 Normal phone with RJ45 socket.
 Lan cables.
 Internet bandwidth.(64Kbps minimum
recommended.)
 IP phone.

20.  VoIP technology hit the Indian Markets quite
late, but has picked up very fast.
 VoIP is much in demand in India, as India has
lots of outsourcing business which leads to lots
of communication expenses with their foreign
counterparts .

21.  Still today there are many places in India
where the bandwidth quality is not sufficient
enough to use VoIP technology.
 The Government Authorities like TRAI and
DOT has not been able to implement policies in
India to encourage the foreign companies to
invest in India.
 Heavy License fees is one of those factors.
