It is very important to know what type of connection is suitable for the users to communicate.
VoIP (Voice Over Internet Protocol) is a service that allows users to interact, send and receive the users voice. VoIP is considered as a service and in order for it to function correctly; the network administrator must consider the entire users situation. This service allows us to make phone calls to land lines and mobile phones around the world over Internet packets.
Like anything else, VoIP has its benefits and drawbacks and ways to improve the service. A solution is introduced as IRIS at the end of the research with a conclusion.
VoIP:
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.
When two users are having a conversation on the phone, bandwidth is very important. Normally a VoIP service that has been installed on a GSM network uses 531 Kilobytes/min (or 8.85 Kilobytes/Sec) of the networks bandwidth. From this, we know now this service cannot take place on a 56 kbps dial-up
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.
Mr. A and Mr. B can do a video conferencing effectively using the protocols SIP
The WAN will link all of the site networks together which will in turn boost the network speed and the way employees communicate. The communication aspect of the new network will incorporate a VoIP system and will be managed at one central location. “The great thing about VoIP is that it taps additional value from the already existing infrastructure without additional costs” This will provide the highest quality of phone network will saving on the cost of out phone services.
This option allows the business to enjoy free calls and voicemails sent by the internet. Therefore it needs a fast and reliable internet connection.
Also, some broadband phone services just dump their audio into the Internet resulting in widely varying data travel times giving you significant sound delays.
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.
4) Against the background of your answer to questions #1 and #2, how should Cisco distribute VoIP products? Through voice VARs? Data VARs? Or both?
NOTE: To ensure that quality of service requirements are achieved, the Voice-over IP (VoIP) service over the wide area network (WAN) should be protected from packet losses, latency or jitter. To reach this objective, the network performance can be managed using statistical techniques such as traffic engineering. The standard bandwidth of an integrated services digital network (ISDN) data link would not provide the quality of services required for corporate VoIP services. WEP is an encryption scheme related to wireless networking. The VoIP phones are usually connected to a corporate local area network (LAN) and are not analog.
VoIP is a relatively new technology and so the benefits are just beginning to be realized. VoIP technology has the ability to completely change the telephone industry as we know it. Big changes are in store for the way we use telephones and this section will address some of the changes to expect. Obstacles still stand in the way of progression and there are problems that need to be addressed before this technology can take over.
GlobalPhone has many services to offer the fast-paced, communication-driven business world. Enjoy the savings and flexibility from their VOIP plan. Or the hassle-free installation of
7. Voice VLAN: This VLAN is exclusively for Voice over IP (VoIP). The network must be customized for this traffic by having adequate bandwidth, giving the VoIP traffic precedence over other network traffic, and minimal delay (Cisco, 2014, Section 3.1.1.4).
Skype is a texting and voice chat application that permits clients to associate with each other from any part of globe with Internet access. Skype is one of the most well-known and leading voice communication services in the world. Skype is free, which implies that you can check the product without making any investment. It was created by Niklas Zennstro and Janus Friis in 2003. Five years later, eBay one of the world’s largest online commercial center purchased Skype for $2.6 billion. Finally, in 2011, the software giant Microsoft purchased Skype from eBay for $8.5 billion. Skype has nearly 663 million users worldwide. Through these numbers, we can know how much popularity Skype has gained within a short span of time.
VoIP is a revolutionary technology in the communication industry. VoIP which stands for Voice over Internet Protocol is a method of converting the voice signal from your telephone into digital signal that travels over the internet. VoIP sends voice data in packets using IP rather than traditional circuit transmissions.
The audio function is similar to a standard phone call with one exception. The normal operation entails retrieving or typing in the phone number of a person’s office, home, mobile or Skype number and pressing the off hook button just like most
