Not withstanding the hardware backward compatibility mandate, there have 

been times throughout the life of the SoundPoint IP / SoundStation IP phones 

where certain dependencies on specific bootROM and application versions 

have been necessitated.
This table summarizes some the major dependences that you are likely to 

encounter:

In addition to the bootROM and application dependencies, there are certain 

restrictions with regard to upgrading or downgrading from one bootROM 

release to another bootROM release. These restrictions are typically caused by 

the addition of features that change the way bootROM provisioning is done, 

so the older version become incompatible.
