We are about to install a new PBX that has VoIP capabilitites and I want to make sure I am heading down the proper path for my VLAN infrastructure to support these new capabilities. For this install we have a multiple building comples with a data VLAN for each building as well as a seperate VLAN for my server farm. If we convert all the digital phones to VoIP, we will have approximately 200 phones over the entire complex.
I know that I need to have the VOIP traffic on a different VLAN than my desktop traffic. It also looks like I use the switchport voice command instead of the switchport access command to configure the new vlan. Is there anything else I need on the switchport level? All other steps for configuring the voice VLAN is the same as configuring a reglar VLAN correct? With the phone beconnected between the wall and the PC, it "knows" the different VLANS?
In regards to how the PBX and VoIP interfaces reside on the network(i.e. CLAN card, etc.), should these interfaces be in the voice VLAN or is best practice to place them in my server VLAN?
I have my VLANs seperated into buildings and/or floors. Should the voice VLANS follow the same pattern or is best practice to have the voice VLAN cover everything?
I have started reading through the Cisco IP Telephony Planning, Design, Implementation, Operation and Optimization book from Cisco Press. I am also being sent a giude from Avaya in regards to setting up VoIP. Is there any other reference material recommended??
