This varies by local telco.  We have repair service on 1-555-1611 for
residence and coin and 1-555-1515 for business; the "Public Service
Center" (for dealing with public and semi-public coin phones -- not
COCOTS I think) is at 1-555-1717.  I don't know how out of area 555 is
handled; 700-555 is a per carrier option, except that +700-555-4141
seems to have become the standard "carrier ID" number.

Not strictly correct; an AT&T customer may access other carriers' 700
services by prefixing the appropriate 10XXX prefix, just as customers
of other carriers may access the AT&T services by using 10288.  (And
obviously this only applies to locations with equal access and service
available from the desired carrier.)
