Narrative:
Center cleared us out of FL270 to cross tonto intersection at 12000 ft and 250 KTS. The FMC showed us 3500 ft above optimum descent profile for the restr. Therefore, I used idle thrust, full speed brakes and a descent rate in excess of 6000 FPM at vmo/mmo. I told the first officer to tell center we would not make the restr. Center told us to contact approach. We did arrive at 12000 ft MSL by tonto but were still doing 320 KTS with speed brakes extended. First officer checked on frequency with our altitude and that we were slowing to 250 KTS. Approach very aggressively demanded our actual airspeed (which was 295 KTS and slowing). The controller's manner caused us to have grave concerns about a violation. I tried to explain that center had kept us high but he did not want to hear it. The center controller could have helped the situation by telling us that airspeed was more important than altitude rather than just passing the buck to approach. The approach controller's manner caused us to start worrying about everything except flying the aircraft.

Title: ACR ACFT UNABLE TO MAKE XING RESTR IN PHX AIRSPACE.
Narrative: CTR CLRED US OUT OF FL270 TO CROSS TONTO INTXN AT 12000 FT AND 250 KTS. THE FMC SHOWED US 3500 FT ABOVE OPTIMUM DSCNT PROFILE FOR THE RESTR. THEREFORE, I USED IDLE THRUST, FULL SPD BRAKES AND A DSCNT RATE IN EXCESS OF 6000 FPM AT VMO/MMO. I TOLD THE FO TO TELL CTR WE WOULD NOT MAKE THE RESTR. CTR TOLD US TO CONTACT APCH. WE DID ARRIVE AT 12000 FT MSL BY TONTO BUT WERE STILL DOING 320 KTS WITH SPD BRAKES EXTENDED. FO CHKED ON FREQ WITH OUR ALT AND THAT WE WERE SLOWING TO 250 KTS. APCH VERY AGGRESSIVELY DEMANDED OUR ACTUAL AIRSPD (WHICH WAS 295 KTS AND SLOWING). THE CTLR'S MANNER CAUSED US TO HAVE GRAVE CONCERNS ABOUT A VIOLATION. I TRIED TO EXPLAIN THAT CTR HAD KEPT US HIGH BUT HE DID NOT WANT TO HEAR IT. THE CTR CTLR COULD HAVE HELPED THE SIT BY TELLING US THAT AIRSPD WAS MORE IMPORTANT THAN ALT RATHER THAN JUST PASSING THE BUCK TO APCH. THE APCH CTLR'S MANNER CAUSED US TO START WORRYING ABOUT EVERYTHING EXCEPT FLYING THE ACFT.
