We have an old Cisco 2620 XM router with the wrong version of firmware to create ISL links.  We are installing an Avaya IP Office VOIP system which has to use its own DHCP Server.  Is there a way on my routers DHCP server to exclude the Avaya phones, possibly by MAC address so that I can have 2 dhcp servers on one subnet
