So, is the Polycom firmware matrix wrong about this phone/firmware compatibility, or am I missing something? The bootrom has also been upgraded to the latest without any problems.

Without knowing what version of the SIP application is already on the 
phones it is hard to say. But it sounds as if your phones are loaded 
with SIP 3.2.x or lower. To upgrade beyond 3.2.x you will need to put 
the 4.4 version of the BootROM on your provisioning server. With SIP 4.0 
and later (and I believe 3.3 as well) the "BootROM" (now called the 
updater) is included in the sip.ld file itself. The 4.4 version of the 
BootROM updates the phone to look for the new updater inside the sip.ld 
file. It should ONLY be used to upgrade phones from SIP 3.2 or lower to 
SIP 3.3 or higher.

Hope this helps.
