The only way to tell if it's an intra- or inter-lata call is to look up the prefix in a suitable table. As I've mentioned in other messages, from Princeton NJ it is possible to dial local intra-lata, local inter-lata, toll intra-lata, and toll inter-lata calls all using just 7 digits. It's very hard to tell how much a call will cost. > 2.

I haven't tried dialing a redundant area code. > 3. Is there anything else I should be asking but am not? How many multi-lata area codes are there other than 609? I know that 914 in New York is one, as is 408 in California. Are there many others? Regards, John Levine, johnl@esegue.segue.boston.ma.us, {spdcc|ima|lotus}!esegue!johnl
