Need exact aircraft config set up to get ATC to recognize Speedbird

I recently installed PMDG's 737 900 and then downloaded British Airways. However FS9's ATC will not use "speedbird" as the call sign. If anyone out there has the 900 in the British Airways would they please write down the exact config file for the 900. I have tried atc_airline=Speed bird....atc_airline=Speedbird....atc_airline=Speed Bird but instead of ATC say Speedbird 777 climb and maintain 5000, it merely says 777. If anyone has a setup where ATC says "Speedbird 777 climb and maintain..."I would love to have you aircraft config file setup.
