That could theoretically occur in this country if some IXC were using 'line side" termination (Feature group A or B, IIRC) rather than "trunk side termination" (Feature group C or D). But this is obsolete and I think line side termination was eliminated at least 10 years ago. Thus, the only way it could occur is if some carrier were terminating on a telephone or PBX in the calling area, which now happens only for VOIP. (Until recently it did sometimes occur with cellular carriers for similar reasons.)
