Has anyone got a Yealink phone to work with POE over CAT 3, 6 conductor cable?
I have confirmed that 802.3af supports 2 pair POE/data.
https://en.wikipedia.org/wiki/Power_over_Ethernet (assuming wiki is correct)
And the Yealink phones support 802.3af class 2 POE, so I should be go to go.
The part I'm assuming at this this point is the use of 568B pinout in the jacks. (more specifically, using pins 1, 2, 3, 6)
You are not technically using T568 at all. You are making use of the T568B standard for reference and using pins 1,2,3,6.
568 A or B does not matter. it simply has to be the same on both sides. I personally like B just because it is what I first used when I learned CAT5 wiring.
