I have a system for this

create the VLAN structure
interface vlan 400
interface vlan 401
ip helper address 10.10.210.10
interface range fast 0/2 - 4 (assuming 3 phones)
switchport mode access
switchport access native vlan 400
switchport voice vlan 401

ensure the VLAN is shown as up up
show ip int brief

ensure you have your IP helper address
show run interface vlan 401

ensure you can ping the CUCM from the VLAN
ping 10.10.210.10 source vlan 401  (or source 10.10.201.1 or whatever your
Voice VLAN ip is)

usually if I can do these things I have no trouble getting my phones to get
IP's from CUCM and register.  I also ensure the CDP and VTP is in the
correct modes.
