PT] All US carriers charge the same rate to a foreign administration for carrying a call. This is a US regulation, and prevents problems when multiple providers have to deal with a single entity. There is no advantage to BT, or any others, to give a routing preference. Commonly, calls are routed in proportion to their receipt in the sending country, i.e. if 80% of the calls to BT come from AT&T, and 20% from MCI, than that same proportion will be preserved on the calls from BT. Collect, or credit card calls of course are routed to the owner of the account. Herman Silbiger The above information although generally true, may have errors in the details.
