[comp.dcom.telecom] Using an alternate LD carrier for coin calls

ilya@polya.stanford.edu (Ilya Goldberg) (07/08/89)

I have noticed the new explanation cards posted on Pacific Bell
telephones specifying the default LD carrier's name as well as
giving instructions on how to use an alternate carrier (i.e. 10XXX
codes), but until now, the default carrier has always been AT&T.

Well, today, I was using a Pac Bell payphone which specified that
all coin calls default to AT&T while credit card, collect, and
other operator-assited calls default to US Sprint.

COCOT owners can choose any LD carrier they want.  What about the
local telephone companies who own the majority of payphones -- are
they free to choose carriers or do they have to give some share
of the 0+ calls made from payphones to every LD carrier which provides
operator services?  If the local phone company can choose any carrier,
then why would they choose different carriers for different phones?

Local newspaper articles a few months ago mentioned that it was
technically very difficult to make coin calls default to some other
carrier.  They didn't say why.

The choice is made by the owner of the property on which the phone resides,
up to and including the local municipality.
