Voice Over Internet Protocol Term Paper

When it comes to VoIP phone systems, the "Vo" part refers to voice over, and the IP part stands for having your phone calls routed over the Internet. Many business owners have opted for these phone systems because they are cheaper than having numerous and separate phones in the office. You do not have to use the network or telephone service to make phone calls, which lowers the overall cost. At the same time, there are advantages of using IP technology for telecommunication.

Cell Phones – They use both voice and data with the use of cell tower to send data from the network to the cell phone.

The goal of this document is to come up with a proposal for the company IP PBX system. In this proposal I will introduce several different Voice over IP vendors, each fully qualified to becoming our company’s new IP PBX system. Only one of the vendors will be selected based on the criteria laid out by the Chief Information Officer.

I would also request that active monitoring of the VoIP network be assigned to a member of the IT team to ensure no unauthorized devices were linked to the network. Additionally, this IT member would be required to run intrusion and antimalware detection software on the system and ensure that it is maintained at the highest state of readiness. This involves running checks of the system constantly to ensure no unauthorized devices have been linked into the system, verification of the integrity of the VoIP tunnel and monitoring the system to verify connectivity, and software integrity. The easiest layer to add for mitigating risk over the VoIP network is the users themselves. Sure we have given the users access Tokens allowing them to choose a complex password that only they know, but we also must educate the users. Through education we can teach the

     The first company that comes to mind when we talk about VOIP is Vonage. Like phone companies, Vonage offers phone service. However, Vonage performs this service over your existing internet connection. They will give you any number from any state you wish and even give you fake numbers called virtual phone numbers for an extra five dollars a month. They offer all the same features as a regular phone service with some extras such as auto forwarding when your connection goes down. Vonage also offers a real nice voicemail system where you can setup voicemail to be sent to your email account or have your cell phone alerted when someone calls you and leaves a message. The one

The act of using voIP over the internet opens the window for many internet attacks and security and protocol issues. Protocol vulnerabilities include numerous attacks all at once, security vulnerabilities, and attacks exploiting private and crucial information. VoIP is a freely opened environment, therefore, there is a large window of opportunity to the hacking world. What this means is that the internet is easily assessable to a multitude of people, some with good intent and some with malicious intent. Because this is made to be so easily accessed, it is easy for a person to act in a criminal manor and disrupt the flow of private conversations. To help eliminate some of these issues SIP has evolved as the signaling protocol to recognize and handle mass media sessions for the internet and its extremities. These vulnerabilities are so severe because attackers can exhaust and misuse available resources, create false responses to malicious requests, or discover more security vulnerabilities.

With so much technology and applications being developed these days, there is one technology that seems to be touching people’s lives since it was introduced. What technology is that? It is Voice over Internet Protocol or VoIP for short. When Alexander Graham Bell invented the telephone in 1876, he had no idea that his invention would morph into what it has become today. This paper is describing how VoIP was created, its industry trends, technological developments, and how VoIP is utilized.

VoIP stands for 'V'oice 'o'ver 'I'nternet 'P'rotocol, popularly known as IP telephony. As the term says VoIP tries to let go voice (mainly human) through IP packets and, in definitive through Internet. Thus Voice-over IP (VoIP), is the transmission of telephone calls over a data network like one of the many networks that make up the Internet. While you probably have heard of VoIP, what you may not know is that many traditional telephone companies are already using it in the connections between their regional offices.

Individuals have some great things to look forward to. Many already communicate over the internet for free (not including ISP cost) in a simple fashion by chat rooms, instant messaging, and email. Some are already using VoIP to replace their current telephone provider due to the lower

For example, if you wanted to do business in Egypt, you could use a virtual phone number to route calls from Egyptian locals to your offices located in any city, such as London, Los Angeles, or Toronto. It’s an extremely low cost method for your business to stay in contact with Egyptian consumers and stay competitive in the Egyptian market.

With the ever changing phone industry, the phone has shifted from being able to allow us to communicate through long

Skype is one of the least expensive Voice-over Internet-Protocol (VoIP) service. Furthermore, the subscriptions are done within minutes. Skype can be downloaded and run on any platform with free of cost. Any Skype client can interact with others, using the Skype call which is available for free. A group call up to twenty-five members is possible. To improve its revenue, Skype started using freemium model. This strategy clearly states that it offers free services to the customers and also lowers the cost by Skype’s P2P technology.

Voice over Internet Protocol has the same result as a normal telephone line but the main difference is in the architecture design. VoIP services communicate over a digital network rather than traditional telephone line. Data is being sent and received as “packets”. Packets are not encrypted and other users might be able to listen to the users conversation. In this case the administrator needs to set the servers default to encrypt the packets.

Voice over Misconfigured Internet Telephones (VOMIT) is a product apparatus that siphons voice TCP/IP parcels running on Cisco 's telephone framework, and its restrictive convention known as thin (SCCP). It works on the system by getting bundles, which can change over to a wave voice document for tuning in (Persky, 2007). All the more as of late, an item called SipTap has exhibited the ability to capture decoded SIP based VoIP activity. SipTap has snatched the consideration of the VoIP group. SipTap siphons voice calls, as well as guest ID style data, marking the call originator, beneficiary, term, and time. Corporate surveillance through an item like SipTap is an unsafe recommendation

Business and consumers are already taking advantage of the cost savings and new features however some larger companies are withdrawing away from VOIP because it costs too much to replace their telephone systems. Since large companies have a large capital investment they cannot afford to get rid of their old phone systems. However smaller companies have older analog based systems and are migrating to VOIP.
