It depends whether the call is local or long distance, which is a different question from whether it is in the same area code or a different area code, unless you're in Mexico. (In Mexico, your area code is exactly the same as your local calling area.) For example, from San Francisco, California, in area code 415, there are local numbers in area codes 415, 650, and 510, but there are also long-distance numbers in area code 415.
To make it even more complicated, a "short-distance" call (long distance, but carried by your local phone company) may cost more than a coast-to-coast long-distance call. A call from San Francisco to Eureka, CA, on Pacific Bell will cost more than a call from SF to New York.
Bottom line: it depends.
Depending on what you mean by "the area code of a call," it's either the area code of the phone you're calling from or the area code of the phone you're ringing. The fact that the call is "collect" (reverse charges) is irrelevant.
Typically a "house phone" (such as in the lobby of a hotel) can only call extensions within the same company or building.
To call an Australian number from another country, you need to dial the international dialing code for your country, followed by the country code for Australia (61), and then the Australian phone number you wish to call. Make sure to include the area code if necessary.
The phone code 016975 is associated with the United Kingdom, specifically serving the area of Newtown in Wales. This code is used for landline telephone numbers in that region. If you receive a call from this code, it typically indicates that the call is originating from that area.
