Did you plug five Aastra phones? I'm suspicious about how that scenario worked, I mean, as far as i know Aastra phones should register as a zero PoE class, that means it would reserve up to 12.94 watts no matter how many watts uses. So, my guess here is even if the phone use only 5 watts, the switch already reserved 12.94 watts for it. I would love to see what happens if you plug a sixth phone or figure out if you used an Aastra phone. Can you tell us what model/brand you used? Dimensioning PoE devices over capable switches has been a new issue which involves many factors like those described before. Regards, PD.
