| I have customers with 30 to 40 IP phones on an internal network. They seem to work great.. One of the things you may want to look at when deciding on the IP systems is whether or not you can do VLAN tagging on the IP phone. If you can do VLAN tagging then it is safe to say you can use your Computer and phone on the same cable and still keep the voice and data segmented from each other. If it doesnt do VLAN tagging then you can still run the phones and the computers on the same cable but you lose VLAN managability and I think you will lose some of the QOS. You may also want to make sure the network switches you are using that support Gigabit also can support 100baseT mostly because most IP phones cannot run on Gigabit yet. I have some customers that are running two different networks completely, one for voice and one for data. It is more cost to doing it this way but there are no finger pointing when something is not working. |
