Avaya 9608 Handset with LLDP on Cisco 3750 Switch

We have recently had many problems with relying on DHCP to pass Phone settings to our 9608 deskphones. I was able to enable LLDP on my 3750 switch and that resolved much of the problem. My deskphones  are now able to discover and join the voice vlan.   My issue is this. I see no way to pass the MCIPADD and HTTPSSRVR parameters to the phone from LLDP, even though I've found Avaya documentation that says it can be done. Without being able to pass those, the phone will have to have them programmed in manually. These options were previously passed to the phone with DHCP option 242.  I expect the 1st question you will ask is why don't I just go back to DHCP and you'd be right to ask it. To make a long story short, we are having a bunch of ACK errors on the phones and it is a problem with how they pull addresses from the DHCP server. To this point, nobody has been able to solve that problem; not even our Avaya  vendor, so I'm just trying to come up with another solution that does not require me to statically assign IP addresses on all my phones.
