Configure Cisco Cataltyst Express For DHCP on Cisco-Voice VLAN

I have a new Cisco Catalyst Express 520 that has a default configuration of two VLANs (default, Cisco-Voice).  When I plug a Polycom IP phone into the switch, it does not get a DHCP assigned IP address from my Cisco ASA 5505.  How can I tell the switch (or the ASA) to assign the Polycom phones with a DHCP assigned IP address?  It seems that the smartports recognize these phones as IP phones and assume they will be getting their IP address from a phone-only DHCP server.  We'd like for the single DHCP server to provide addresses for phones and other devices.

Do you have an interface on the PIX for both the voice and the data VLAN?   The PIX will only hand out DHCP to devices connected to a subnet that is is directly connected to.  Can you include your switch configuration?  Have you thought about using the switch for DHCP?  I'm not sure if the 520 supports it, but try typing "IP DHCP POOL <POOL NAME>" from the globabl config mode to see if it lets you into DHCP configuration mode.

The 520 doesn't have a CLI.  Everything is done via the Cisco Configuration Assistant.
