hello!

I have an unmanaged Cisco router from the ISP which provide voice to the internal network. I want to put an ASA 5510 between the router and the switch.

how can I configure the ASA to pass the voice vlans ? do I need to configure sub-interfaces?

THX

What is providing routing for your vlans ? I assume the switch must be layer 3 or is the ISP router providing vlan routing?

I only recommended transparent mode because you would have to collaborate with the ISP to change the configuration of their router if you want the ASA to do the routing.

so long as the router uses 802.1Q for doing vlans, you just need to create subinterfaces with the correct vlan tags on the outside physical interface; one for data and one for voice.  after that you can route it however you want.  You'll need to make sure the static and acl commands are created properly to not interfere with the voice vlan, but you should be fine.
