Deer hunting is very different from moose hunting. The former necessitates much stealth and silence, the latter not so much. Actually, for the type of hunting that I do, doing some noise while hiking in the forest interspersed with some calling seem to work best. The idea is to mimic the sounds of a moose travelling in the bush...
Calling is only a part of the puzzle. Do not overly rely on calling to get the moose to you. A better option is to actually identify areas with suitable cover, and then hike to those areas while calling occasionally. The main thing is to go where the moose is at, especially if it is not responding to calls... Personally, I think that the chances of success are greatly increased by putting less focus on calling near trails and crossings, and spending more time out in the woods where the animals are more likely to be. Many hunters are "afraid" or unwilling to leave the trails and go out into the bush, do not be one of them...
As mentioned by many above, be prepared to work and make sure that you are properly equipped (4-wheeler, chain saw, saw, come along, etc.) to get the moose out of the woods. A moose is much much bigger than a deer...

The work really starts when the beast is on the ground. Depending how far you are, it can easily take 6 to 8 hours (and even more in really remote areas) to bring the beast back to camp.
