I am not 100% when this feature was exactly introduced but please see below as a workaround:
Automatic Caller ID Scrolling on SoundPoint IP 321, 331, and 335 Phones
As of Polycom® UC Software 3.3.0, when the SoundPoint IP 321, 331, and 335 phones receive incoming calls, the caller ID will automatically scroll from left to right. Auto-scrolling stops once the call is connected, but you can use the left and right arrow keys to scroll manually.
If you wish to restore the original "old" functionality please highlight this to the relevant team via raising this as a Feature Request => here <=
