VVX phones generally not responsive



I have been having issues with Polycom phones, basically since the VVX came out.  The phones do not seem to be responsive, in the sense that the phone seems to hesitate when pressing keys.


I have tried many different brand of phones, and while for many reasons I prefer the Polycom brand, all of those other phone brands are perfectly responsive, like old PSTN phones - press a key, get an instant reaction. Only the Polycom feels like it's too busy to respond to my key presses, as if it had some sort of complex background process going on.


This is true whether I have 5 BLF or 50, but it feels worst when there are many.


This is annoying but tolerable to office workers, but receptionists are going out of their minds. 


This has been true on 5.2, 5.3 and not 5.5.2.  5.5.2 feels better, but it`s not quite what I feel it should be.


Is there any best practice in terms of configuration to get responsive phones? What settings could impact this? Given the size of Polycom provisioned config files, I've got a hunch that there is some setting somewhere that I just need to find, but I haven`t found it yet.


As I wrote, all other phones in the same environnement are perfectly responsive so I don`t think it`s network related. My "test phone" RAM is 33% used, and the CPU hovers around 20% utilization.
