I'm implmenting VoIP on our network across 30 buildings on a University campus. Would it be best to put all the VoIP phones into a single vlan or splits them in separate vlans for each building? Am using a software based PBX system (Asterisk).
This is really more of a 'it depends' thing. Keep in mind that any more configuration you do will add to your management overhead. One advantage of putting them all in a separate subnet/VLAN is that you might be able to do better QoS or anything on them.
