ITL-24D-1 IP Phone on SL1100

[RMS_Tech]

I've got an SL1100 at version 7 and need to add an IP phone. The problem is, they are hard to find and very expensive for some reason. I see in MB 15-26 there is an option for phone type of "ITL-12/24 Button without 8LK Unit". I have several ITL-12D-1 phones that came from an SV8100 system but I cannot get them to work on the SL1100. Once the phone can see the PBX on the network, the phone screen shows "Not Support" no matter what I do.
On the phone, I've set the 1st server address to the SL1100 and the SIP port to 5080 and upgraded the Firmware on the phone to version 5.0.7.0.
On the PBX, I have an available IP Terminal License (3 actually) and have allocated ports in the IP Phones List. I've tried Plug & Play, Automatic, and Manual registration types in 10-46.
Are these phones compatible with the SL1100? If so, any advice on how to get them to work would be much appreciated.

They will not work. UX/SV series have their own phones. SL1100 has been discontinued for quite some time. SL2100 IP phones might be an option but you would need to check.

Those phones are not compatible on the SL1100.
