Hello,
I've taken over a network with an IWATSU system that has all of the handsets statically/manually programmed. I'm re-architecting our network and will be changing addresses. Instead of reprogramming 200+ phones manually, I was hoping these phones will work via DHCP. Unfortunately, my phone vendor does not seem to have gotten DHCP to work correctly and has since been programming everything manually. Could someone help with giving me some hints or point me to documentations that may assist?

Currently our phones are on a separate circuit, while data is also on their own. In the new network, i'm hoping to go from wall plate to phone, to PC. Using VLAN tagging and DHCP options should work. I've gotten DHCP to work with our data network, but when a phone is plugged in it doesn't seem to be passing on to the correct VLAN. I've tried using vendor class IWATSUIP and predefined an option of 132 (dot1q VLAN ID according to IANA) with my VLAN's hex.

Thanks in advance.
