Digit 1 Outpulsing
The d i git 1 may or may not be required at the public network office to which the

routing can be determined according to the called country, rather than handling 
all international calls alike.
Operator and Operator-Assisted Calls
Calls to an o perator (0 by itself) with 0 as the attendant access code, require a 
three-second time-out or dialing of the # digit before the call is processed. 
Operator-assisted calls (0 plus a 7- or 10-digit number) require 10-digit...
