Hello,
I'm planning a VoIP deployment and the idea is to hook up the PC in the phone PC port to use only one switch port for both peripherals, I will be using a switch SG220-50P with Avaya 9608G phones, and a cloud service for the Avaya IP Office, this remote office will have no more than 25 pc's/phones, and the big question is...
What would be the best practice for this setup?
Meaning... Do I need to create 2 VLANs (Voice and Data)?,
Do I need to enable QoS for voice vlan?,
Do I need to tagged the switch port if I create 2 vlans?
Is there any specific configuration that somebody recommends me to use in a switch level?

I probably wouldn't bother unless you have extremely low bandwidth WAN. But, if you want to look at this: http://sbkb.cisco.com/CiscoSB/ukp.aspx?vw=1&docid=c59f9a9b0d2b455c8d14e1ea6675ffa1_Configuring_Quality_of_Service_using_DSCP_Trust_mode_on_Cisc.xml&pid=2&respid=0&snid=3&dispid=0&cpage=search

Here is what I would do:
macro auto disabled
voice vlan id 100
all ports you want phone and/or PC:
switchport trunk allowed vlan add 100
The Avaya phones should use LLDP and the switch will tell them to tag to VLAN 100.
Then you need to consider your router/firewall and make sure it connects to a trunk port to allow VLAN 100 to route to your provider and maybe provide DHCP on VLAN 100 for the phones.

Thanks Brandon,
And how would you configure QOS?
