Does DHCP option take precedence over options 176 and 242?

Hi, I am working with our voice engineers to implement Avaya IP phones at a new site. We have created the necessary DHCP scope options 176 and 242 (with TFTP server specified) for both the data and voice VLANs. However, when the phone boots, it seems to be trying to contact the TFTP server specified in option 066 instead. This option 066 is used during the workstation bootup process. My question is, could this option 066 have taken precedence over option 176 and 242?

Option 176
MCIPADD=12.235.120.150,MCIPPORT=1719,TFTPSRVR=12.2 35.120.217,L2Q=1,L2QVLAN=0000,VLANTEST=30

Option 242
MCIPADD=12.235.120.150,MCIPPORT=1719,TLSSRVR=12.23 5.120.217,HTTPSRVR=12.235.120.217,HTTPDIR=SIN,L2Q= 1,L2QVLAN=0000,VLANTEST=30

We are using Avaya 9650 phones.

I have to explain a little bit on the L2QVLAN=0000 portion. The DHCP is controlled by another team and the team mentioned that they have a script which will pick up the 3rd octet from the IP address subnet and put that value in the VLAN so our VLAN ID will have 3 numbers which matches the subnet's 3rd octet.
