CLRNC CONFUSION ABOUT OCEANIC ENTRY POINT LEAVING EGPX AIRSPACE.

Narrative

WE WERE ASSIGNED TO FLY FROM AMSTERDAM (EHAM) TO FROBISHER BAY (CYFB). FLT PLANNING AND ATC FILING WAS DONE BY COM/SOURCE. A FAX COPY OF THE FLT PLAN AND WX DATA WAS IN OUR HANDS. THE FLT PLAN INDICATED THAT OUR OCEANIC ENTRY POINT WAS TO BE 59N10W. AFTER DEP; AN HR FROM OCEANIC AIRSPACE; WE REQUESTED OCEANIC CLRNC. WE WERE TOLD TO STANDBY FOR THE CLRNC. WHILE COMMUNICATING WITH SHANWICK; WE RECEIVED A REQUEST FOR OUR ETA AT 59N10W; WHICH I FORWARDED. I MONITORED THE 'CLRNC' FREQ EXCLUSIVELY THEREAFTER UNTIL THE OCEANIC CLRNC WAS ISSUED. WHILE I WAITED; I HEARD THE CTLR QUERY A NUMBER OF OTHER ACFT AS TO ALTS ACCEPTABLE FOR THE XING. SHE ALSO CLRED A NUMBER OF ACFT TO ENTER OVER 59N10W. EVENTUALLY OUR CLRNC CAME THROUGH AND I COPIED AND READ BACK THE ENTRY POINT AS 59N10W. THE CTLR ASKED ME TO SAY THE LAST 2 FIXES IN THE RTE AGAIN DUE TO GARBLED XMISSION. I COMPLIED AND RESTATED THE 2 LAST FIXES; WHICH SHE THEN ACKNOWLEDGED; BUT AT NO TIME WAS HER ISSUANCE OR MY READBACK OF THE ENTRY POINT QUESTIONED. AFTER RECEIVING THE OCEANIC CLRNC; WE ALSO RECEIVED REVISED DOMESTIC ROUTING; WHICH WE TOOK CARE TO VERIFY. SOMEWHAT LATER; WE HEARD A NEW CTLR TAKE OVER THE FREQ; BUT THERE WAS NO NEW DIRECTION ISSUED TO US. WE HAD PROCEEDED TO WITHIN 9 1/2 MI OF 59N10W WHEN THE CTLR SAID 'YOUR ENTRY POINT IS 60N10W; WOULD YOU PLEASE PROCEED DIRECT?' TO THIS I REPLIED 'NEGATIVE; WE WERE CLRED OVER 59N10W.' THE CTLR SAID 'I'LL CHK ON IT; BUT YOU'LL HAVE TO FLY HEADING 360 DEGS.' I SAID 'ROGER; HEADING 360 DEGS;' AND THE CAPT TURNED TO THE NEW HEADING. SHORTLY THEREAFTER; THE CTLR ISSUED A NEW CLRNC TO 60N10W THEN AS PREVIOUSLY CLRED. THE REMAINDER OF THE TRIP WAS UNEVENTFUL.
