To use 1+ for "toll alerting", in locales where intra-NPA can be toll, and inter-NPA can be local, you have to incur one of those sets of increased expenses. And the 'inconveniences' to the customer.
Not really. Billable status of a call is known up front in today's all-digital NANPA coverage area (to my knowledge, the last mechanical and/or electromechanical switch disappeared before 2002, and it was somewhere in rural Quebec). In fact, I ran into a telco recently in a 10D/1+10D dialing area that -- only if the customer subscribed to the unlimited domestic LD plan -- allowed dialing any US number without the leading 1 as simply 10D. Conversely, some jurisdictions are very strict about use of the leading 1 to indicate toll status thanks to localized court cases establishing that "hidden" tolls are a Bad Thing. -- -- Todd Vierling <tv@duh.org> <tv@pobox.com> <todd@vierling.name>
