Web Phone Calls

Especially to judiciously allocate international telephone numbers among various lands and cities of the world or between mobile phone providers the telephone numbering plan is used. But dial plans (international calling codes) are not really the same thing as numbering plans. And the closed numbering plan, it is normal in regions like North America or Australia supposing that there local numbers are used in combination with appointed length region codes.

There also exists an open numbering plan functioning in a number of places of the world that haven’t defined it by now. For this numbering plan the size of the calling code and subscriber’s telephone number can vary. The numbers formed by the open plan are dialed variously. You have to be aware which digits should be anyway dialled (they form the local number) and which can be omitted (area dialling codes).
Still now the numbering plans as well as international dialling codes are different from country to country despite that the International Telecommunication Union or ITU makes good tries to standardize the system. ITU tried to have 00 as a general international access combination for all the state members. But the suggestion was not obligatory for the state members so just several of them assigned the new international code and the rest countries like United States and the members of the North American Numbering Plan remained on their conditions.

According to the international numbering plan area codes are fixed. Country code means a nation or a number of countries. The biggest possible size of the full international phone number is defined by the E.164 rule that regulates the country codes at the international level. It is just supposed that the nation itself distributes the telephone numbers on its land. District country codes then may be with:

- A fixed size, complete of for example one digit in Australia or 3 in Canada and the USA.
- A non-defined extension. This is when the number of digits varies like in Austria or Germany (from two up to 5), like on japanese isles (from 1 to five) or like in Syria (from one to 2).

- Particular norms supposing that the subscriber’s number has the dialling code in its structure, like in Norway. This way the “closed” numbering plan is applied. Speaking of some of the nations, they have zero as a trunk-line calling code. It’s popular in areas like Italy and Belgium, the Netherlands, african countries or others.

The dialling code usually serves to measure the price of the call. Generally making calls on the numbers within your area calling code is much cheaper than making calls on the telephone numbers with some other dialling code.

Still as in States the costs for home calls are set by the state representatives while interurban calls are charged by competition, it happens so that home calls seem to be less cheap.

But it can appear so that one area dialling code covers a large territory. The calls then should be evaluated according to the interval of the connection.

The prices are usually assigned for area sections which are about 0-6, six-twelve miles and more. Usually they are defined by valuation centers. However, as the regulation of local telephone services stopped that all went the other way.

It’s now becoming popular among the people to take the so-called “all-you-can-eat” plan (an assigned rate of nearly 30 dollars monthly as actual for spring 2008 allowing to reach any place of the USA).
There may be special dialing codes. They are created usually for cell phone systems in those areas where they are covered by the caller or for free, premium accounts.

There also may be different special variants. E.g. in countries like Egypt dialling code define nothing because the prices remain the same for the whole country and in Great Britain the dialling code is made of 2 parts each with its cost.
