You shouldn't need to install the whole device pack update, just the 
cmterm-88xx-sip.10-2-2-16.cop.sgn file.  That's all we did when we 
needed support for the 8831 conf phones.  You don't need to install the 
whole cmterm-devicepack file to get support for one phone, that just 
makes it more convenient to get all of them upgraded at once.
