P315 and PBXAct: missed calls not shown

Dear all,
I’m experiencing a problem in our PBXAct installation (restapps module latest version 16.0.36.31)

In our P315 phones we cannot list latest missed calls.
When a call is missed, in the phone the icon appears, but when we go into missed calls list, there aren’t latest missed calls but only old missed calls starting from yesterday.
Same when reviewing the entire call history, only the laatest outgoing and answered calls are present, not the missed calls.

Moreover, I believe that missed calls that went to voicemail are not listed, but I need to make some tests to confirm this.

Is it a problem of the latest version(s) of restapps? Or we are missing something in configuration?

Thanks in advance.
Lorenzo
