Internet phone calls – VoIP Basics

Saturday, 23. January 2010. 11:16 von offsiteam.com

They have seen the commercials and read the messages advertising for phone service with a computer: very low monthly fee to keep all the calls that you want to, your phone number forever, and voice quality as good as a landline. You’ve heard the claims, and you have the term “VoIP is one.” Here’s the scoop. VoIP stands for Voice over Internet Protocol, and it does what the name suggests? It transmits voice over IP packets over the Internet. It is also Internet telephony. It is easier to understand VoIP, if you know a little about our telephone system? PSTN (the Public Switched Telephone Network) and a little about the Internet. Their traditional landline calls transmitted by copper or fiber optic cable in the ground or on the telephone pole with a cable connected to your home. If someone calls, a nonstop route between the two phones and the information flows continuously made in this loop. As you are paying your bills, the longer the distance, the more expensive the conversation. VoIP works a little differently. It works with the Internet, which is a packet-based network. Packet-based simply means that instead of sending a continuous series of information, it sends small packets of information. With VoIP, your voice is converted into a digital signal that travels over the Internet. There are three ways that this can be done: 1) with a VoIP phone, 2) a computer with speakers and a microphone, or 3) using a regular telephone with a VoIP adapter. Since the IP packets are tiny in comparison, unlike downloading a file, this happens all in real time how your normal phone. Benefits of VoIP VoIPBecause provides services via the Internet if the device in place there are a number of advantages. The main reason for the popularity of VoIP is its cost advantage. With regular phone service, you usually pay a monthly fee for local calls and a per minute for long distance calls. Internet connections are charged with a monthly flat rate only. With VoIP, no per-minute fee for long distance calls, you would not incur these charges. If you are international calls, VoIP certainly save lots of money. If you have used the Internet for your traffic and phone calls, you could get rid of a monthly payment. The remaining cost advantage is that because it uses a broadband Internet connection, it uses existing infrastructure efficiently you are already on the computer. There is only minimal hardware and software to buy. Disadvantages VoIPThere are a few disadvantages to VoIP. A major is a QoS or Quality of Service. Since voice packets enter your information to be rather a continuous stream of information, there could be delays problems, strange noises, echoes and noise. VoIP quality depends on many factors? Broadband connection, your hardware, your Internet Service Provider (ISP) and the destination of your call, just to name a few. While VoIP made significant progress in the last 5 years in terms of quality of service, it still has a way to go. Another disadvantage is that in the event of a power outage, you lose the ability to make and receive calls if you have a backup battery for your computer. Be the case of conventional telephone service, the cable connected directly to the telephone line and the phone company delivers electricity, regardless of your home or business electrical system. So you can not tend to lose a radio signal through the loss of power with traditional service. Another criticism of the VoIP service is the historical problems with 911 emergency services. With traditional phone service, the 911 system can identify the location and number of the call, because it is connected and will be run locally. With VoIP are, please call over the Internet and the actual signal can be directed considerable distances before they go to a local 911 service centers. Thus, geographically, the 911 system could have problems, are identified. Most VoIP services today include what an enhanced 911 Service known. This is a process by which the signal travels over the Internet brings with it a physical address for the calling location. Currently, VoIP equipment vendors may be an additional fee for this service. Companies that want to use VoIP to need money to save all the security issues that are considered too. This is because, with VoIP, information sent over the Internet. As with any computer connection, it is possible that a hacker can intercept the information transmitted. It is important to examine the VoIP equipment provider network, as they route data, determine what firewalls or other protective measures are necessary for security purposes. If you are willing to look to VoIP for your phone or fax service, you can visit electronics retailers, large discounters and online search for information. There are a variety of VoIP providers currently. The device, which is used, the cost for the equipment, the cost of supplies and the cost of improving services and should be compared. It should maintain the system to acquire and use the provider that you are best suited for your needs in terms of how many phones you to work the system in relation to what kind of security you require and the cost of the acquisition of equipment and the service. You can see a telecom management services for a cost analysis to determine whether VoIP is a good fit for your company. VoIP is still a new technology, and hopefully there are more and more improvements and innovations in the coming years will be.
