Narrative:

All 3 pilots heard clearance as 'allersburg 4N.' during departure phase, controllers asked what departure we were on. My reply was 'allersburg 4N,' to which the controller responded, 'you're supposed to be on the 'microphone 4N, go direct alb.' we did to direct 'alb,' and nothing more was said. There were no traffic encounters, or further mention of routing.
