You can configure it. Eg configuration...
switch(config)# int fa6/1
switch(config-if)# switchport access vlan dynamic
switch(config-if)# switchport voice vlan 10
Configure your VMPS server configuration in global mode.
This configuration works because all the packets from phone are assumed to be tagged and arrive with voice VLAN ID and so these packets are not subjected to the VMPS server query process.
