Voip Service Providers, Internet phone service provider

What is ISP?

ISP literally means Internet service provider (ISP) or provider (supplier). This is a service (in most cases pay) that can connect to the Internet.

Why Use an ISP?

Unless you have a dedicated line (in addition to the phone line), you can not connect directly to the Internet using only the telephone line. In fact, the phone line was not designed for this:

• This was originally designed to transfer "voice", ie a frequency modulation in the range of tones of voice
• Phone servers only serve to start a conversation from a phone number
• Unless you use a special service, it is usually impossible to have more communication between two points ...

Then, the Internet service provider is an intermediary (connected to the Internet via specialized lines) that provides Internet access through a number that is entered using the modem and allows to establish the connection.

How your ISP provides your Internet connection?

When the connection to the Internet through a service provider, the communication between the computer and the ISP is established using a simple protocol: PPP (Point to Point Protocol), a protocol that allows two remote computers to communicate without having an IP address.
In fact, your computer does not have an IP address. However, one of these IP addresses is necessary in order to access the Internet, mainly because the protocol used on the Internet is TCP / IP protocol that allows a large number of computers located using these addresses to communicate.

Therefore, the communication between you and your service provider is established according to the PPP, which is characterized as follows:

• Telephone
• Initiation of the communication
• Check the username (login id or user)
• Checking the password

Once connected, the ISP provides a static IP address which is preserved during the Internet connection. However, these addresses are not fixed because the next connection the service provider will provide one free of their addresses (and thus will be different, since according to their ability a provider may have several hundred thousand addresses).
The connection is therefore a proxy for connection is the service provider who sends all the requests that are made and who gets all the pages that were requested before returning to the applicant.

That is why, for example, when you have access to the Internet via an ISP, you must download the email in each connection, it is usually because the service provider who receives the email (it is stored in one of servers).

Differences between ISP

Choosing an ISP depends on several criteria including: the number of services offered and their quality. What, then, these criteria?

• Coverage: Some ISPs only provide coverage in large cities, others offer national coverage, ie a number which is the cost of a local call regardless of where it is called
• Bandwidth is the total speed offered by the ISP. This bandwidth is shared between the number of subscribers, so the greater the number of subscribers, the lower the bandwidth (the bandwidth allocated to each subscriber must be greater than its transmission capacity to be able to provide The service is of good quality)
• Price: This factor depends on the ISP and the type of package chosen. Some ISPs now offer free access
• Access: unrestricted: Some ISPs offer a package where we consider the connection time, ie can not exceed a certain number of hours of connection per month. If this occurs, the charge for the call receives an increase in the price (additional minutes are very expensive). Some providers even offer without subscription fees, ie, you pay only for the communication (but, obviously, this is more expensive than a local call)
• Service: This is a team dedicated to responding to technical problems (also called "technical support" or "Customer"). ISPs usually charge for this service (sometimes called by € 1.35 and then 0.34 € / min)
• Additional Services:or quantity of email addressesor available space to create a personal page (HTML)or ...
  

Understanding of the different packages on offer

The Internet Service Providers (ISPs) offer subscription rates and packages for accessing hierarchically categorized Internet ...
Internet Free Internet without subscription; very tempting, but how can such free offers?

• Paid subscription with unlimited access
• This is the traditional package. Is to pay a flat fee each month (approximately 10 to 30€). With this package Internet access is unlimited, ie you can connect as much as you want during the month ... only pay-per-call charges (the cost of a local call).
• Such a package usually provides (or more) email addresses, as well as space to build a personal page Paid Subscription access
• This type of package has the same features as the previous package, with the difference that this subscription is more economical, but the connection time is limited. Use outside the defined time period increases the cost per additional.
• Access to the Internet without subscription
• Warning! This service is not free ... Can connect only occasionally paying for access with a higher cost of call per minute. It is only appropriate for people who connect to the Internet infrequently (a few hours a month) and does not include benefits such as space for a personal page (however, free accommodation is available excluding ISP).
• Internet Service Providers Free
• How can these companies offer free access?
• Advertising allows companies to offer such packages. In fact, since they are connected, you can see several banners.

Telefonica will use a German provider of network services for internet

The Spanish telecommunications company Telefónica will enable the German provider 1 & 1 Internet using its infrastructure in Germany to offer combined services and internet telephony.
Telefónica Germany reported today that 1 & 1 Internet connection will provide a complete telephone and internet browsing through the net of the Spanish company in this country so that their customers do not need a telephone connection added.

Telefónica Germany and 1 & 1 Internet cooperating since 2005 in offering phone calls over the Internet, the installation of speed connections to the network and the distribution of video on demand service Maxdome, the German TV company ProSiebenSat.1.

The director of Telefonica Germany, Johannes Pruchnow, said that with this agreement "we confirmed our strategy to invest heavily in one of the most modern networks, and more future in Germany."

The spokesman for 1 & 1 Internet, Andreas Gauger, believes that "Telefónica's infrastructure is the basis of our full internet connectivity and telephony, we want to reach more than 60 percent of German households in the future."

Services Provided In Internet Telephony

All Phones Internet can provide the same services, because they use about the same technology, but business reasons, or technological development, mark significant differences between different providers.When it comes to deciding which Internet Phone, is essential to make the comparisons necessary to make a decision.

Hardware:
Special hardware equipment is not essential and you can access the service with a good computer, a headset with microphone and a good banda ancha.
To begin, you do not need more.
If they determine to a significant initial investment, dude, or checking the service ask another user, and compare it with that you can receive without these facilities.

Turnover:
This theme, seemingly unimportant, is also vital.
Most providers is unable to issue invoices with VAT discriminated. And if your company consumes about $ 200 per month in telephony this can mean a loss of tax credit exceeding $ 500 annually, which is not little.

The Customer support:
Check. A communications provider must be able to meet customer service that promises (either high or low) and if you can not satisfy it is because their infrastructure is not adequate and you could face problems if the contractual services.

Access from the traditional telephony:
If you acquired an Internet telephony service, which can be use to call it from the main cities of the world, from telephone, paying local rates.
And the process should be simple. Dial and conertarse. From a phone. But DO NOT sit at a computer, enabling software, register, and pray that at the other end connected also to speak. Because that is not Internet telephony, but voice chat.
Internet Your phone should have a number that can be dialed from any traditional phone.

The Voice Mail:
One of the most beautiful treasures of the Internet telephony is the Voice Mail or Voice Mail
If you are not facing your Internet phone to serve you, you can leave a voice message, as in traditional telephony, but it arrives at your mail box almost instantly ... and, if desired, can receive an alert tone, in text format in the mail box of your cell phone.
This service is free in most of the suppliers. But check, because some providers advertise the free service but charge a voice mail. And not little.

The free calls to other networks:
Internet telephony is a network such as the Internet itself. And allows for free calls between the networks of 300 internet phone service. If your provider does not offer this alternative because it is not linked to other networks and their performance will be limited.

The packages of Internet - Telephony - Television

The packages of Internet, telephony and television can be beneficial and save you money, but some drawbacks. If the hard times of the economy are juggling in order to reduce their costs, the solution can be found as close as your Internet service, telephony or television.

Intense competition for customers between cable and satellite providers of high speed fiber optics, AT & T U-verse and Verizon FiOS has caused the reduction in rates of Internet service, telephony and television. The prices of packages of the three services fell 20% last year, a reduction that comes to $ 80 a month.

These fares are good apparently only the first or second year of service. However, providers are increasingly unwilling to raise rates after the promotional period, at least in the places with the most competitive markets, said Doug Williams, an analyst at Forrester Research telecom.

A new study by the National Research Center for Consumer Reports (Consumer Reports National Research Center) reveals that subscribers were very satisfied with the services of Internet, telephony and television of the best telecom providers. However, they also found some problems with packages that include a high incidence of complaints about billing, technical assistance and contributions of triple-play packages of some providers.

However, the packages seem appropriate for many households, especially if you are a customer of one of fiber optic transceivers or one of the top cable companies. By averaging the scores from readers for their Internet services, telephony and TV, Verizon FiOS and AT & T U-verse were the most successful suppliers in a consistent way, but Verizon was below average for customer service as clients of the three services (triple play).

Choosing

Check your options. Use our Ratings to see how their services compare with the competition. Only a few cable companies, most small, they were even close to matching the high satisfaction of customers consisting of companies with respect to the fiber optic Internet service, telephony and television. (Check with AT & T and Verizon fiber optic availability, although they are limited spreads quickly). Most cable companies are below the most prominent in total satisfaction, such as satellite television providers, whose services are included in the packages with DSL Internet service and telephone telephone company partners.

Test a package. With most providers, you get more services and save more. The packages also allow you to integrate other services such as show the number of those who called on the TV screen, which is provided with some packages and cable telephony. The triple-play offerings are often more attractive discounted, like the installation would not get free when you subscribe to only one or two services. Likewise, it could ensure low rates for a longer triple-play that if you sign up for individual services.

Do not discard the option to the letter. The access to less than three service providers allow any flexibility. For example, you could access the Internet and television services via optical fiber, perhaps with an introductory rate along with an economic telephone service Voice over Internet Protocol (VoIP stands for English) as the third company Vonage, which was among the best phone service providers in our rating and price highlighted.

Distribute their services among several companies that also avoids the flaw in a computer network or delete all their telecommunications services at the same time.

While packages often ensure maximum savings, we find at least one case where the cost of a service provided by an individual was in fact lower than in a package.

Consider the safety call. Cable VoIP service and telephony fiber optics requires a battery backup during power cuts. Could get one with your service or purchase at a cost of approximately $ 45. However, these packages provide an average of 8 hours of operation, so you might not have phone service during a power outage that lasts longer.

The 911 emergency service also varies between technologies. The phone service fiber optic system uses the same reliable one traditional phone line. The latest telephone services by cable and other VoIP services and 911 depending on the provider that provides emergency services to their local address, a federal requirement. The agency also required to inform customers that the new VoIP emergency service "may be somewhat limited when compared to traditional 911 service." To add VoIP service to another fixed basic telephone service, which costs about $ 20, for use in calls to 911.

Settings with other attributes. As our Ratings show, vendors differ more than in the general satisfaction of its customers.
For example, the scores vary widely for the selection of TV channels. Service with fiber optic, satellite and some cable channels are offering all in high definition. However, the number of channels should not matter as much as with the programming that you could wish in particular, as in packages of professional league football NFL United States, exclusive of DirecTV.


In general, fiber optics and satellite have a service charge for severance, but no cable. In addition, some providers may offer to maintain the initial rate after passing the promotional period if you sign a contract. (We reject the offer).

Getting the best prices

Check the tariffs, then check again. Check the web site providers to find the best prices. Ask also for a customer service representative if the price you have offered is really the best offer for the company. Then, consider a check again, as we have found that rates may change, according to the representative who received the call.

Negotiate. It may be useful, particularly in areas where there is competition between cable providers and traditional phone company, as well as its promotional fare is about to expire. Ask for a reduced price or free extras, installation, or as a premium channel at no additional cost. If you accept these "gifts" will make sure not to charge them automatically to continue to receive when the introductory offer.

Ask about billing models. Before signing a contract, ask for a summary of all charges for the first month and beyond. Make sure that the figures include taxes and fees and charges at one time as you charge to maintain their current phone number. Try to get written information. Then check the numbers again matched against the actual invoices.

Adjust the extras. The typical download speeds of 5 megabits per second (Mbps) and loads of 1 Mbps with the Internet service is sufficient for most people, and often, and fiber optic cable beyond those speeds anyway. As a general rule, do not pay more for faster service unless you download or share videos often extended or other very large files.

Most of the plans based on fiber optics or VoIP include caller ID, answering machine and unlimited local calls or long-range United States, Canada, Puerto Rico, and sometimes to other countries. Verify that these features do not disappear or increase the charges on your bill when the promotional period lead. If you make frequent calls to countries not included in this plan, evaluate the possibility to add an international calling plan.

How to Choose an Internet Service Provider

Having tried internet and everything it offers, you will most likely want to stay connected. To go online you need an Internet Service Provider (ISP). Is a company that will provide an Internet connection. Whether you are looking for your first ISP or a better or cheaper: it may be difficult to find the most appropriate service provider.

To start, determine what type of internet service you want to use. There are essentially two types. A dial-up connection that uses your existing phone line to connect to the internet, has many disadvantages. It is the slowest type of service. Keeps your busy, unless you install another line or a device to announce that someone is calling while online. Puede tardar varios minutos para realizar la conexión. The only advantage of dial-up service is its cost. It is the cheapest way to connect to the internet. The dial-up service can be considered if costs are an important factor, or if you only plan to use the internet occasionally.

For people who want to connect more often and do not mind spending more, the option is a broadband connection. This connection is fast, does not hold the telephone line and is always on, so you will not have to wait for the phone to dial to connect. If your computer is on, the Internet is instantly available. There are three popular types of broadband connections: DSL, cable and satellite.

After deciding what type of connection desired, it will be time to start looking for an ISP. An internet service provider can be a company like Earthlink or America Online. These ISPs are involved solely in the Internet business. It can also be a telephone company, p. ej. Sprint, or a cable company, p. ej. Time Warner. ISPs and telephone companies involved can provide dial-up connection or broadband. The cable companies generally offer only a broadband connection. Find out first with the provider of cable and telephone from home. Call them or check their websites to compare prices and services. See then dedicated suppliers of Internet services. It is often possible to find local service providers in the local newspaper ads. You can find national service providers looking for in internet or in magazines and on computers.

The price is important. However, do not select an ISP that charges only for what, otherwise they may feel unhappy when not connect or can not get help. When choosing an ISP should not reject the importance of service quality and availability of a good support service. Often the only way to evaluate these services is studying the views and experience of other users. Then talk with friends, relatives and neighbors. Ask them if they are happy with the ISP they have.

Web sites like Broadband Reports, in www.broadbandreports.com help you determine the services available in your area also have bulletin boards where people describe (in English) their experiences, recommend or disapprove services banda ancha. Reading these individual reviews is an enlightening experience that will be done before deciding which service to use.

By studying the various providers of Internet service, you should know exactly what is included with the account. Most of them offer the software you need and help you set your computer to connect to the internet for the first time. Many of them offer free calls and unlimited technical support. Two things that vary are the number of email accounts that the service provided and the storage space on the network that comes with each account. If you use the connection to dial, you will need a modem in your computer, most computers today come already installed. If you use a broadband connection you need an external cable or DSL modem. Usually the ISP owns these items and are provided as part of the service, although sometimes there is a charge for this equipment. Then be sure to ask about it. The dial-up connection is not cost of installation, except for a telephone cable, very cheap. Just connect your computer to a phone line. The installation of broadband connections is more complicated and must be made by the ISP. It is possible that installation costs vary, this should also be investigated.

If traveling, make sure the service you are considering offering internet access without dialing long distance charges, if you want to check your email while traveling. When comparing broadband services, be sure to check the bandwidth to download and upload each service offers. Note also that sometimes you can get similar services with two separate companies. For example, if you are in an area where Time Warner Cable services, Internet service Earthlink uses the main link of Timer Warner. This means that the service will be physically identical. However, it is possible that Earthlink and Time Warner Cable Road Runner (internet service from Time Warner Cable) offer different prices, installation charges and incentives, it will be convenient to compare.

The contract requires you to is also important. Is registering for a certain period of time? Will terminate the service without being charged penalties? Do not forget that in deciding which company to use its Internet service are also important customer service, availability, quality and degree of reaction to their problems. There are many details that have to be investigated to select an ISP. A careful examination of the ISP and the services it offers will help you make an informed decision, to smile for many months.

Internet Service Providers

Internet connections can be classified according to their speed (bandwidth), the connection type (permanent or temporary) and the physical environment and type of connection (fixed or mobile telephone, ISDN, ADSL, fiber optics ... ). Different combinations of these three parameters determine the connection speed, the price of the service and the services we can assemble.
Connection speed and transfer rate

Internet is a network of data transmission, and thus the connection speed defines the speed of access to their services. The transfer speed is measured in bits or bytes per second, with corresponding scale factors (k = 1,000, Mega = 1,000,000, Giga = 1,000,000,000).
In connection speed must differentiate between the maximum speed of the means by which we connect (connection speed) and the maximum speed of data transmission that provides the service provider.
To communicate with another system, the transfer speed depends on connection speed of each state and all intermediate systems and networks that data must traverse to get from one end to another.
The speed at which we receive the data (transfer rate) changes every time, depending on the state of the network, the ISP provides the service, the number of simultaneous users of the provider of the computer ...
In the case of working from a local area network, we must also distinguish between the speed of connection to equipment and the network connection speed through the Internet connection you have with our organization.

Permanence of the connection

Standby, we refer to the necessity of conducting an operation to provide connection.

1. Permanent connection: a firm or organization contracts with a communications provider (Telefonica, BT, Jazztel ...) a link connected to the Internet. In this way, a network of computers can get all your equipment is permanently integrated into the Internet. This is an expensive solution, to which must have special equipment for communications, but provides higher transfer speeds, and allows its use is shared by more users.

2. Temporary connection in this case, access is contracted with a provider of Internet connection (Teleline, Mundivia, Jazztel ...), which is active only during the time that we make the call. It is oriented to individual users, using a personal computer and a modem, using the basic telephone network (ISDN or if they want better benefits), to establish communication with your provider, and through him, with the Internet.

Almost all providers offer flat-rate connections, ie pay a fee for the connection, regardless of the duration.

The connection is essential if we are to mount an Internet service visible from the outside (eg the website of our company), meaning that other users can access one of our systems regardless of the state of our network or when the day.

Temporary connections used a protocol called PPP (Point to Point Protocol) which is responsible for validating the access name and password) and share any information with our supplier.
Medium Connection

The most common are:
Copper telephone wiring, which can use a standard modem (up to 56 Kbits), an ISDN modem (two lines of 64 K) or a DSL modem (from 256 to 1.2 Mbits).
Coaxial cables or twisted pair, typically used for local area networks (10 or 100 Mits). Also use the metropolitan cable networks, such as ONO.
Fiber optic networks for greater scope in that it allows connections to more speed and greater distance between links.
Price Connection

In the case of permanent connections, the price of the connection depends on the bandwidth requirements (the maximum speed that can communicate via the link, guaranteed minimum speed). Normally you pay a monthly fee for the concepts of physical connection and data flow hired.

Should go to the web pages of information for each provider to learn of the various bids in force in each case.
Supplier Connection

Are companies that provide Internet access. Until recently, it was necessary to pay a monthly fee for access, but today many of them give us free internet access, pay only the telephone call (also offer other services such as email address, space for publish web pages, discussion areas ...).

You can learn how to connect to the following Web addresses:

• JAZZTEL
• ONO
• ORANGE
• TELEPHONE
• TELE2

Elements for the connection
1) Computer and operating system

To connect to the Internet, we need an operating system that provides communications software (TCP / IP, PPP dialup, ...); All versions of Windows, Macintosh and Linux have all the necessary elements to connect, although Linux is a little more complicated by the characteristics of the operating system (however, is the fastest and most efficient of all).
2) Modems

There are two types of modems in terms of its connection to computer, internal or external. The first space-saving and cables, it is only necessary to connect a computer to the phone. However, they may be more complicated to connect and configure because it is necessary to open the computer and available hardware resources (IRQs. ..) for operation.

External modems connect to your computer using a serial port, so its setup is simple and easy to share among multiple computers. But more is needed cables (telephone, computer and power supply).

If basic telephone network connection settings must be at least a 56K modem supports the V.90 standard, approved by a communications company (Telefónica) and ability to update their firmware (the program that operates the internal modem ). In this way we ensure that we can update it in the future.

For ISDN or ADSL modems, the connection will be the provider that we recommend an approved modem.
3) Applications

Each Internet service is an application 'client' which allows to collect data and display them. For example, to visit the many websites available on the Web requires a browser such as Internet Explorer, Netscape Navigator, Opera, etc ... For all Internet services, there are many versions of clients, free of charge (freeware) assessment must then be paid (shareware) or to pay.

Operating systems Windows, Mac and Linux installed bring more current versions of the most common applications (web, ftp, telnet, irc) so it would be possible to start work immediately. The following directions allow you to download updated versions of almost all the tools.

Internet Phone Service Provider

Internet Phone service provider refers to communications services—voice, facsimile, and/or voice-messaging applications which can be transported through Internet, inspite of public switched telephone network (PSTN). The basic idealogy of the origin an Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets. For the transmission and communication over the Internet the process is reversed at the receiving end.

By using this internet phone service the customers can make and receive Voice calls over IP (VOIP). This can be achieve only by using ordinary touchtone also known as telephoneFi phone which can be used without using U.S cell phone provider.

Vonage was found to be one of the most reliable VoIP vendor among all those who took part in the service provider of Internet telephony. This included AT&T CallVantage, Primus Lingo, SkypeOut service, Verizon and of course, Vonage.. These companies are instrumental creating AT&T, Sprint and UUNet networks
