Sure. I followed the instructions here:

However, there was one important fact missing. By default the presence 
feature is turned off in the Polycom's (at least that was the case with 
my Polycom 501's). It needs to be turned on before any of the other 
settings take effect. To turn it on you can edit sip.cfg. Look near the 
end for the <feature> section. Feature 1 is presence, changed 
feature.1.enabled from "0" to "1". This is also covered in section 
4.6.1.23 of the Polycom admin manual.
