Hello all, I know this is done and I think I figured out how to do it but I don't want to reinvent the wheel so here goes. I am looking for a program that will sit on the PBX. This program will intercept DHCP reply packets destined for phones, inject "option 66" into the packet and release it back onto the network. Some of you might be wondering why I want a program like this. Simple. Lazy clients. They don't want to mess with their network infrastructure to assist us with automated deployment of SIP devices. They also don't want 50-100 devices connecting to an off site server downloading 20-40MB of firmware on a reboot. The PBX is not hard coded with an IP address. It's DHCP. They were willing to allow the PBX on the network and assign it a static DHCP address. Is what I am looking for not possible? Does someone have a sensible solution that doesn't involve dropping the client (yes someone suggested that)? Thanks in advance for any help you can give. DigiLord
