Hi guys,I'm looking to add voip phones to our current network and was wondering how best to configure it given the current setup. Currently, it's a flat network 192.168.1.1 /24 with our 48 port switch on eth1 port of ubiquiti edgerouter 4. The switch has multiple desktops (~10) connecting to some win servers (setup as a terminal server). The voip phones would be added at each station sitting behind the ip phones on the same line. In order to power the phones, a second poe switch will be added as well. 1) Firstly, should I be plugging one switch into another daisy chain style so the phones can see the SBC controller I've setup on the win server? In doing so, all uplink data will be running through a single shared 1GB line which is not great but it's only 10 users with no heavy data activity. 2) If not, I would have to plug it into the unused eth2 port of edgerouter and it will be sitting on a different subnet all together. Would it be bad to have the phones look for the SBC on a different subnet if I keep the win server on the original switch? My subnets can communicate as I have no firewall rules between them. 3) It's probably overkill, but if I wanted to setup VLANs and QoS on the second poe switch how would it work as the desktops are sitting behind the ip phones? It's an aruba 1930 and I've read people having the "ports untagged for standard data, and then also tagged for the voice VLAN. This way if they use the passthrough port on the phones for their desktop/laptop, they get an address on the data VLAN. The phones are configured with the VLAN Tag info and pick up an IP from the voice controllers in the office". I don't have a good grasp on VLANs and how that works, does it sound correct? “Voice” on the VLAN automatically applies the QoS so that would be setup automatically I suppose. 4) If going the VLAN route, how would I be dealing with smaller down stream switches (5 port) to be used where more then one jack is needed? Would they have to use the same VLAN tagging found in the main poe switch in order to work properly?Thanks for any insight and sorry if my wording is confusing
