Narrative:
After becoming radar contact between bradr and bitta, we were given present position direct to upp and pilot's discretion to FL260. A few mins later, while coming up on our descent point, we received a TA from another aircraft at our FL360. The other aircraft was spotted at our 1:30 - 2 O'clock position. Seconds later, an RA 'climb, climb' was issued. The first officer disconnected the autoflt and climbed about 400 ft using TCASII guidance. During our climb, ATC issued 'traffic at 2 O'clock position, same altitude.' the other aircraft (a B757) passed directly under us, indicating FL355. B757 reported in to ATC before we did. The controller said 'sorry.' told them who we were and where we were going. We were given a frequency change and sent on our way at about the same time.

Title: B767 CREW GIVEN A PLT'S DISCRETION DSCNT RECEIVE A TCASII RA WARNING ON A B757 CONVERGING AT APPROX THE SAME ALT.
Narrative: AFTER BECOMING RADAR CONTACT BTWN BRADR AND BITTA, WE WERE GIVEN PRESENT POS DIRECT TO UPP AND PLT'S DISCRETION TO FL260. A FEW MINS LATER, WHILE COMING UP ON OUR DSCNT POINT, WE RECEIVED A TA FROM ANOTHER ACFT AT OUR FL360. THE OTHER ACFT WAS SPOTTED AT OUR 1:30 - 2 O'CLOCK POS. SECONDS LATER, AN RA 'CLB, CLB' WAS ISSUED. THE FO DISCONNECTED THE AUTOFLT AND CLBED ABOUT 400 FT USING TCASII GUIDANCE. DURING OUR CLB, ATC ISSUED 'TFC AT 2 O'CLOCK POS, SAME ALT.' THE OTHER ACFT (A B757) PASSED DIRECTLY UNDER US, INDICATING FL355. B757 RPTED IN TO ATC BEFORE WE DID. THE CTLR SAID 'SORRY.' TOLD THEM WHO WE WERE AND WHERE WE WERE GOING. WE WERE GIVEN A FREQ CHANGE AND SENT ON OUR WAY AT ABOUT THE SAME TIME.
