I have a question... I have environment that has a Voice VLAN already DHCP scope is configured with option 66 pointing to TFTP server e.g: 10.28.2.20 and Avaya phone are running. We need to put cisco phone on the same vlan. So i configured DHCP scope with option 150 pointing to TFTP server e.g. 10.14.10.25 on the same voice vlan. Most of my cisco phones are working.. Couple of Cisco phone are picking OPTION 66 which points to wrong TFTP leading to registration error.. My question is can I force Cisco phones 7841, 7811 phone to always use option 150. Please let me know
