Has any one any experience with Infoblox DHCP server for avaya J1xx phones, we have done a packet capture and can see the request for option 242 in the DHCP Discover but on the DHCP offer back form Infoblox we never see the option 242 in the DHCP offer. Option 242 is setup in Infoblox is there anything that needs to be specifically set to get this working? Upto now all deployed phones have been TDM so have never needed the DHCP but starting to roll out IP now. As the phone never gets off the data VLAN the option 242 is just L2QVLAN=xxx but obviously phone never moves to Voice VLAN as it never receives the option.
