The first direct-dialed long-distance telephone calls were possible in the New Jersey communities of Englewood and Teaneck.Customers of the ENglewood 3, ENglewood 4 and TEaneck 7 exchanges, who could already dial telephone numbers in the New York City area, could place calls to eleven major cities across the United States by dialing the three-digit area code and the seven-digit directory number.
The fictitious number (02) 3456 7890 in Sydney, Australia, is published in the form +61 2 3456 7890 for international use. In countries participating in the North American Numbering Plan, such as the United States, Canada, and some Caribbean nations, this number is dialed as 011 61 2 3456 7890, with 011 being the international call prefix for the NANP and 61 being the country calling code of ...
However, at the outset, to set up an international call, multiple operators were required: one to originate the call and one at each national gateway to complete a call via either ringdown to a local operator or Operator Toll Dialing.

[3] Until the late 1960s, some outer London exchanges did not offer direct dialling, and their numbers could be identified in the directory by being printed in light type, unlike normal exchanges, whose first three letters appeared in bold type.
This is known (in the US) as a Direct Inbound Dialing (DID) number, or in the UK as a Direct Dial-In (DDI) number. Where Caller ID is available, it may be possible to use the same DID number for many different subscribers, as the callback system will be able to recognise each subscriber's registered number.
For example, since European cell phones have "calling party pays" billing, calling a London cell number can cost over US$0.20/minute, while calling a London landline can cost under US$0.01/minute. Inbound calling prices are more varied, particularly in the US. Some providers offer flat rate pricing "per channel" (simultaneous call leg) while ...
