Hello Enriquezd,
You would first have to create your 2 VLAN's. They will need to match the VLan tagging for the rest of the network.
Trunk the port going to the rest of the network with Data Vlan Untagged, Voice Tagged.
Trunk the ports going to the phone/Computers with Data Vlan Untagged, Voice Tagged.
Since these switches don't do CDP or LLDP-Med you will need to manually configure the phones Voice Vlan.
A Switch that works much better in a Voice Environment is the SG or SF series switches They currently don't have a Stacking model, but work is being done to have one available. Not sure on the ETA. The ESW also has some Voice capabilities for automated configuration.
I hope this helps.
