Hi Mike, the SG 200 supports LLDP med. Here's a document I wrote for the SX300

It's pretty much identical to the SX200.
If you will keep the phones connected to a port and not move them, you can probably use the QoS function of the switch, manually set the QoS configuration on the port then over ride ingress DSCP (much more aggressive, but cool) which can be found on the Quality of Service tab.
