[comp.dcom.telecom] International Calling Request?

ubiqui@uncecs.edu (Frank T. Winstead) (09/29/89)

Hello,

  I'm looking for documentation on making long distance calls from the
US to other countries.  Specificly I would like to know the number of
digits in telephone numbers for different countries.  I have access to
various documents which list Country and City Codes. What I need to
know is how many digits should follow these codes.  I have seen from
numbers that work that this is not always the same for all countries.
The main campus library has a fair collection of International/UN/US
government documents.  So even a pointer to some CCITT paper or such
would be helpful.

  I'm requesting this because part of my job is to send FAXes for
people who are sometimes confused about international telephoning.

Thanks,

Frank Winstead

[Moderator's Note: The number of digits following varies from country to
country, and frequently, even within a country. That is why AT&T encourages
the use of the '#' button as a terminator, or carriage return following the
final digit on international calls. It tells our system here to go ahead
and process what it has been given without waiting for more. Perhaps
if you have specific countries in mind, Mr. Covert will respond to you in
email. He is our 'resident expert' on international calls here in the
Digest readership.  By the way, the '#' button also speeds along calls in
any instance in which the network would otherwise have to wait for a time
out. For example, when dialing the number associated with a Calling Card,
one need only enter the four digit PIN; yet the switch does not know that
is what you are doing, and will wait patiently for the other ten digits
of the card for a few seconds unless you terminate with # to speed the
processing. 'Zero pound' hastens the operator in Chicago, I might add. PT]
