Narrative:
We checked in with zan after the handoff from bethel departure. All operations were normal, including hearing the center controller work other aircraft on our frequency. Next call we received from the center controller wasn't operations normal however. He said 'I don't know how to put this nicely, but I've been trying to call you for the last 8-10 mins. I've had to move 2 aircraft out of the way for you.' I replied that we'd been on this frequency ever since check-in and we'd never heard him calling us although we heard him calling other aircraft. Just one of those things I guess. I don't think 2 people could miss a center controller calling them for 8-10 mins. Maybe he thought we were on a different frequency.

Title: FLC OF AN MLG LOST COMS WITH THE CTR FOR SEVERAL MINS. THE CREW DID NOT CHANGE FREQS FROM THAT LAST PROVIDED BY CTR AND ON THE SAME ONE THAT COM WAS RE-ESTABLISHED.
Narrative: WE CHKED IN WITH ZAN AFTER THE HDOF FROM BETHEL DEP. ALL OPS WERE NORMAL, INCLUDING HEARING THE CTR CTLR WORK OTHER ACFT ON OUR FREQ. NEXT CALL WE RECEIVED FROM THE CTR CTLR WASN'T OPS NORMAL HOWEVER. HE SAID 'I DON'T KNOW HOW TO PUT THIS NICELY, BUT I'VE BEEN TRYING TO CALL YOU FOR THE LAST 8-10 MINS. I'VE HAD TO MOVE 2 ACFT OUT OF THE WAY FOR YOU.' I REPLIED THAT WE'D BEEN ON THIS FREQ EVER SINCE CHK-IN AND WE'D NEVER HEARD HIM CALLING US ALTHOUGH WE HEARD HIM CALLING OTHER ACFT. JUST ONE OF THOSE THINGS I GUESS. I DON'T THINK 2 PEOPLE COULD MISS A CTR CTLR CALLING THEM FOR 8-10 MINS. MAYBE HE THOUGHT WE WERE ON A DIFFERENT FREQ.
