Basically any Caller ID not in a standard NANPA format. Seems most carriers rate such calls at the higher intra-state rate. I noticed mod_lcr just chooses the 'interstate' field for any CID that's not technically intra-state. (We don't use the intra-lata field, since our carriers usually don't). If not, what would the bounty be to have such a feature added? Thanks, Damian
