I don't do much with VoIP but I installed a Polycom phone recently. It takes 24V on the DC plug and works fine with a Mikrotik plug pack, but ohhh noooo, it can't work with 24V PoE in, it has to be 48V or 802.11at/af. Thank goodness I had a CRS328 with PoE on site.

I install a lot of W60B’s , the base station is a 5v DC jack ( unfortunately doesn’t support PoE

The phone almost certainly needs 48v - Power up the 4011 using a 48v PSU for a better chance of it working ; )
There's usually nothing special about 802.3af/ad devices that prevents them working with any kind of PoE input - so long as you have the right voltage, and right mode, it should work just fine :)
Cheers! Mike.

Just installed an RB4011 in a client site. They had an existing Yealink W60B phone there, powered by a plug-pack. The specs on the plug pack say 600mA output.
Tried plugging the phone in to the poE port (10) on the RB4011, with no success. The W60B showed no evidence of seeing power. Tried setting poe-out on the port to "forced-on", no change.
The Yealink doco says it requires "IEEE 802.3af, Class 1" PoE. I can't find any such spec for the RB4011, just lots of statements that it is passive PoE.
Is there a trick or should I give up?
