[asterisk-users] Why Aastra uses 48V whereas other IP Phones use much less, i.e. 5-12V

[Zeeshan Zakaria]

Hi,

Why Aastra phones use more electricity, i.e. 48VDC whereas other phones use
much less, e.g. Grandstream and Linksys both use only 5VDC. I first thought
it was because of PoE, but the ones with 5VDC also run fine on PoE. What is
the difference in power consumption then?
