Re: R6_5_18, DHCP Server with IP Phone not working
Not exactly sure what you mean . Are you saying that the tel will not get a dhcp address ? Can you be a little more detail please ? The NBX tel will boot to dhcp after it attempts to boot to layer 2 then to static ip settings in the phone . If there is a dhcp server online then the dhcp broadcasts sent out via the tel will be answered . I am afraid that thats all the tel does so its up to your dhcp server for the rest .
You can start by visiting our knowledgebase as there are a few docs out there in re to the dhcp scopes with option 184 or visit our data forum for the 5500 as well .

Re: R6_5_18, DHCP Server with IP Phone not working
Assuming you are having trouble with phones gettin addreses from DHCP server...
Had the same problem, I originally had my NBX on VLAN1 and DHCP server on different vlan sitting on my 5500.
After trying just about every form of "port trunk permit", I changed the ip on the NBX to be the same subnet as the DHCP server, and the port config on the 5500 for both devices to ACCESS PORT, PORT ACCESS VLAN(server vlan)
Then on the end point switches, add statement for that VLAN.
Then, be patient. My phones needed to reboot and download NBX image several times at first.
