We are running 22.214.171.12441 and not seeing this behavior on our network. We do not use 192.168. in our environment. I do not see any traffic from our phones to port 8612.
IP scanning on port 8612 seems to be a known behavior for a copier company that starts with C(really the company name is blocked on the forums?) network printer drivers. Are you by chance using their printers?
I also tried this out of curiosity with wireshark and a span between the phone, the phones are in one network and the network 192.168.1.0/24 was routed and accessible from the phone, I could NOT replicate it either, the only traffic I can see on my network at all for port 8612 was from hosts using cannon printers.
It would be interesting to see a wireshark capture of the traffic your seeing.
