I don't own that phone, but I do own a SPA8000. As far as the two being compatible with each other, I don't see any issue since the phone takes analog inputs and the SPA8000 has analog outputs.
The line hunting for inbound calls must be supported by the SPA8000 and it definitely is, as long as the VoIP provider can supply a SIP trunk that allows 4 channels (or whatever the number of channels you require). For outbound, the phone must be able to select the first line available. I have no idea about that part but I am guessing it should.
Maybe a good place to start is reading the reviews (lots of them on Amazon, see »www.amazon.com/SB67118-4-Line-Ex···points=1
