Today average customer uses Voice over internet protocol (VoIP) which is latest trend in communication industry. The technology is rapidly advancing because all telecommunication product companies are now investing fund to have more improved VoIP products and services.
This year the VOIP market has picked up. Many corporate have started using VoIP and have realized a large savings of 52-percent or more off their phone bills. Use of wireless VoIP helped hospitals to reduce cost of mobile phones. Technologically VoIP is better than pagers and hence it is getting popular in nursing homes and hospitals.
What are the disadvantages of Voice over Internet Protocol?
VoIP is becoming very popular to business houses but it is still not very popular to residential segment. The qualities of VoIP services are inferior to the quality of call in regular telephone technology due to various reasons.
VOIP technology requires a large amount of data to be compressed and transmitted in a packet format, then uncompressed and delivered, all in a relatively small amount of time. This digitization of analog voice signals takes too long and the callers experience either echo or over-talk.
Regular phone calls function with a delay of no more than ten( 10) milliseconds whereas in the case VOIP the delay is up to 400 milliseconds, meaning that the callers won’t hear each other fast enough to make the conversation flow easily. Due to this delay, either callers will hear themselves talking or they will start talking again before they have heard the other person reply. It is true that this delay problem does not occur for each call.
The disadvantages of VOIP are usually acceptable if the callers are using a free service and the calls are for personal in nature. The degradation of voice quality is not acceptable to corporate houses. Apart from delay in voice conversation, IT security network like firewall sometimes failed to route a VOIP call once it is received.
Moreover, if several people use VoIP, bandwidth utilization also increases. Excess use of bandwidth also increases the infrastructural cost.

Challenges of VOIP in 2007
March 16th, 2010VegaStream’s Introduction to VoIP
January 13th, 2010
Internet Telephony is used to describe a service that enables people connected to the public Internet with a suitably equipped PC to have voice conversation; examples of Internet Telephony providers include Skype. VoIP is the generic term for the technology that enables phone calls to be made over networks running the Internet Protocol, be that the public Internet or private IP networks. It is also the term that is used to describe the technology in a business to business context. One could say that the consumer will use Internet Telephony while businesses use VoIP.
Voice over IP (VoIP) converts the analog signals of sound when using a telephone to a digital format for transmission across a data network and then back into analog when it reaches the receiver. In a VoIP network, digitized voice data is highly compressed and carried in packets over an IP network. The phones can be purpose-built devices for the IP network (e.g. SIP phones) or standard everyday analog telephones. VegaStream core product range allows users of existing phones to take advantage of VoIP networks.
What’s all the hype about?
The reason for VoIP’s popularity is a simple matter of physics. You can put more traffic over the same physical network using IP than you can with traditional telephone technology, Time Division Multiplexing (TDM) as used by the public switched telephone network (PSTN). This simple law is driving many PSTN network providers to migrate their existing TDM networks; that have served them well since the invention of the telephone, to the new IP technology. BTs 21st Century Network is a classic example of this migration.
With VoIP, IP allows us to use a single high-speed Internet connection for all voice, video, and data communications. This is known as convergence and is one of the primary drivers for corporate interest in the technology. The benefits of convergence are obvious. By using a single data network for all communications, it is possible to reduce overall costs.
Furthermore, the business model for data networks, including the Internet allows the customer to remain permanently connected at a fixed price. Meanwhile, when using traditional PSTN, the meter starts running every time you pick up the phone.
The idea of VoIP communication dates back over 20 years however, a greater interest in the applications of VoIP emerged in the 1990’s, with the growth of the Internet. The Internet made it possible to interconnect every home and every business with a packet-switched data network, this saw a rapid growth in VoIP technology. Today, with broadband connectivity the norm not just in business but also at home and even over the mobile, the platform is set for an explosive growth in VoIP.
VoIP Changing the Way We Communicate
VoIP offers a great deal more than cost savings in telephone calls. VoIP technology allows devices to recognize and communicate with each other as if they were connected over a dedicated wire (like the TDM model). It therefore enables video, instant messaging and data conferencing as well as voice. Furthermore all these communications techniques can be used simultaneously allowing people to share images and information as well as hear each other speak – all on the same call.
VoIP communication therefore allows us to actually change the way we communicate with each other. Communicating over the phone with VoIP will be more immediate, collaborative, visual and cost lest. No wonder the market for VoIP equipment and services is the fastest growing sector in the IT industry.

Welcome to the World of VoIP Technology
November 30th, 2009
Welcome to the world of high technology, the world in which highly developed humankind with original thought is far advanced to that of long ago simple civilizations. Nowadays good communication has become one of the easiest things ever to achieve. Thanks to the internet revolution you can access the most distant places on the planet with just by a simple click.
In the good old days someone in Spain had to wait for months to get a correspondence from a person from the United States. Sometimes, a courier died on the way or the message was forever lost. Now you can do these same in just a few seconds via email, with confirmation of being read built in. And yet people are never satisfied and continue to moan. A person watching a video on you tube on the board of the plane and suddenly has to wait for several seconds loading exasperates in disgust.
The world of VoIP telephony is a wonderful invention allowing you to call your neighbor or a friend from another continent. What does VoIP telephony mean? It is a voice conversation over the internet protocol. What do you need in order to embrace this technology? You must have a computer, a good provider as well as internet access. Let us look at the advantages of this technology. Firstly it is that usability and mobility. You can take just a simple access device with your on vacation, business trip or expedition and be sure that you do not miss an important phone call.
VoIP allows you to identify all incoming and outgoing calls, blocking incoming calls, hiding caller information as well as making calls to the fixed telephones and mobile ones possible. Thus it means that VoIP is multifunctional highly useful technology. If you want to use a qualitative VoIP service you must obligatory have a fast internet connection, otherwise it fails and quality will suffer. Up until recently one of the most important downside factors of VoIP tool is that connectively to emergency services could not 100% be .assured. However recently in the US VOIP providers have been issuing guarantees, saying that all callers can now reach 911 services. And also dispatcher will be able to see the caller’s address to provide urgent help.
Of course, VoIP has some drawbacks. But everything is developing and getting there. The services are improving and you can easily enjoy VoIP telephony and hear the voice of your beloved ones. MLL Telecom is glad to provide you with the qualitative services like that of managed wireless networks or hybrid WAN.
