I'm seeing some traffic from the voice VLAN when sniffing on one of my servers. Mostly broadcast, but occasionally unicast traffic between the CMs and some phones.
When I remove the "switchport voice vlan" command from the interface which is connected to the server the traffic goes away. The traffic is untagged and there isn't a phone between the server and the switch.
This is really unexpected since I didn't think the switch would send traffic from the voice VLAN only if it detected a phone via CDP and if it did send traffic I would expect it to be tagged traffic.
