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 But this is obsolete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.)
