BootROM/SIP Application Dependencies
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:
Migration Dependencies
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.
