Window DHCP Server is not allocting IP to Voice Vlan

Hi, I HAVE 3560 Switch, Over that two vlan configure Data & Voice respectively. Voice id Vlan 1 and Data Id Vlan 2.Routing is done on this switch and work as L3 DHCP Server is member of Data Vlan which is connected to another 3560 Switch L2. DHCP Server is reachable.On that both vlan configured. Switch Port configure fr both Vlan ( Switchport access vlan 2 , Switchport voice vlan 1, Switchport mode access) WHILE Connect any pc to port DHCP server assign ip frm Data Pool while Cisco Ip phones are not getting IP. OPTION 150 is configured in DHCP. Over both interface IP Helper is configured and pointing to DHCP Server. For testing point configure DHCP service on switch with voice pool range ;at that moment Cisco IP phone got the IP fron switch DHCP. Now not able to understand why window dhcp server not assigning ip for Voice. Both Vlan are in different subnet and having / 24. Please guide
