[comp.dcom.telecom] Call Setup With Sprint

drears@pica.army.mil (Dennis G. Rears (FSAC)) (12/11/90)

  I have been a subscriber to Sprint for about a year now.  I am
generally satisified with their service but I have been having trouble
with some things.  First, it takes so long to set up a call.  On calls
to Austrailia, It takes 40-60 seconds from the time the last digit is
dial until the connection is actually made.  On stateside calls maybe
a full 10 seconds.  Is this normal?  Also about 30% of the calls to
Austrailia, the quality is terrible; there is a terrible echo.  Is
this the fault of Sprint or Austrailia Telecom?  On bad calls, I hang
up immediatley and call the LD operator.  She reconnects me and the
sound is great.  How can the Sprint LD operator connect me so fast but
I can do it myself.

  On a unrelated note ... Is there anyway I can get the local phone
company (NJ Bell) or anyone to give me a list of all the unassigned
numbers for a particular prefix?  I actually need such a list for
three prefixes.  Failing that is there a service where I can get the
assigned number for a particular prefix.

drears@pica.army.mil (Dennis G. Rears (FSAC)) complains that call
set-up time on calls to Australia is too high.
 
This may not be Sprint's fault. The local telephone exchange is
probably causing some of the delay, because it only forwards the
dialled number to Sprint once it is convinced that all the digits have
been dialled.  This is not a problem with North American calls, since
U.S. and Canadian telephone numbers are all the same length, but for
overseas calls, the local switch waits until a few seconds have
elapsed since the last number was dialled (this is called waiting for
"time-out"). However, the local switch will recognize the # character
as meaning that you have finished dialling, and will forward the
number to Sprint immediately on receiving the #, assuming that you
have dialled a plausible number of digits.
 
(In other words, 011-44-71-xxx-xxxx # will go through, but 011-44-71 #
may be rejected by the local switch as being too short. I realize that
the example is for a number in London, England, not Australia.)
 
This is not specific to Sprint.  It should work with any long distance
carrier with overseas calling facilities (or, strictly speaking, it
should work with any sufficiently modern local switch, since you're
talking to the facilities of the local carrier, not to Sprint.)
