For reference:

A Call is when the 'Call' icon is lit up and your Digimon cries out, you have 20 minutes or less to respond before it goes out by itself. Your Digimon will only do this when its hearts run out or it gets sick/dying. It will also do this when its time to turn out the lights. You also have 20 minutes to clean the screen when it poops before its is counted as a Call.
A Sleep Disturbance is waking it up during its sleep, if it doesn't get its 8 hours of sleep its DP won't be restores so be careful. Training only counts for evolution when successful.
To get a Perfect Digimon keep this under advisement. A Win Ratio of 40% gives you a 1/5 chance of evolution. 60% or more gives you a 1/4 chance and, 80% will give you 1/2 chance of evolution. So even meeting the 30+ battle may still not be enough for evolution. To ensure an even greater chance, battle during the Child stage and achieve as high of a Win Ratio as you can prior to evolving into Perfect.
If your Digimon dies after a full life and was taken very well care of, it may leave behind an egg. This is what is called a "Traited Egg" and once hatched it will give you an extra 10% of evolving to Perfect. The results are cumulative also, so numerous generations of Traited Eggs will add 10% for each generation.
