We try to connect the IP phone direct to the access switch but still not work. Try different device in same model, and still not working. The switch S5700 PoE, support all PoE device as written in datasheet.

The commend poe legacy it will help to backwards compatiblity with 802.3af power standerd using by old Cisco IP phone. The port in the switch connect to the Cisco IP phone model (7960,7940) need to configure with to get the power:

Config all ports in access switch with the poe legacy enable in the accwss switch:

voice-vlan 464 enable
voice-vlan legacy enable
port trunk pvid vlan 364
