Receiving calls while listening to music

I recently upgraded from my iPhone 4 (iOS 5.1) to iOS 6 and it seems to be missing a feature I used quite a lot. I use my phone to listen to the music through headphones, and when an incoming call comes in, I used to double press the middle button on the remote, which would answer the call and keep the music playing in the background simultaneously. Now that action just hangs up the call. I know that one can click the button once to answer the call and then manually go into the Music app to start it again, but it's not practical for me because I do all this while riding a motorcycle - I cannot pull the phone out of my pocket and fiddle with it while moving.

Is there any way to answer an incoming call and play music in the background with only the buttons on the headphone remote?
