SF 302 Phone and Data on One Port

We recently purchased a SF 302-08P to replace a old 3550 switch.  Is it possible to setup the ports for phone and data?  We have a voice vlan and data vlan.  I can get the phone to work however if I daisy chain the computer off of the phone it will pull an IP from the voice vlan.

I am new to the small business switches and know on the 3550 switches you can set the port for a voice vlan and data vlan, is this possible on the SF 302?

See this post;

Also, there is a PDF how-to doc out there that you should look for.  In fact, I think it's posted on the front page.

Here's a document that will help:

This document shows how you create the voice VLAN and assign it to the ports. The data traffic is coming into the switch untagged and is put into vlan 1 by default. If you wanted to put the untagged traffic into a different VLAN, create the VLAN and then set it as the PVID on the ports you need to,

Yes, that's a good doc right there.  It shows how to configure LLDP-MED+trunking on ports to allow phones to send their tagged frames on one VLAN and the pass-through port data VLAN untagged through the switchport.  This is also applicable to non-Cisco phone solutions as well.

I used this document as an example for integration of our Cisco UC system with Cisco 7900 series phones.
