I cannot get the Sangoma S705 phones to turn on when plugged into PoE++ ports.
They work fine from PoE+ ports.
Are there any resolutions to this issue?
I have confirmed with Sangoma that their phones S series and Digium phones do not work with 802.3bt (poe++) at this time, but may allow it in the future.
I put in a new feature request, so we shall see.
In the meantime, I will have to start using different phones, where they cannot be powered by 802.3bt during our network upgrade.
No your switch should be smart enough to not send ++. Something is off on your switch if that is the case as it’s suppose to be backwards compatible.
Oh, I don’t know how the devices decide which standard to use.
We’re using UniFi switches (USW-Pro-48-PoE).
Still, that is what Sangoma support told me, and apparently their engineers know about. I’m just saying it like I heard it.
