missed calls. Yeastar S300


Hello. We use a Yeastar S300 PBX with firmware IP phones Yealink T19P-E2 and Yealink W52H/P. After upgrading the PBX from to, the following stopped working:

  1. During the Call Pickup, on the phone from which it was intercepted, the missed call is not displayed.
  2. During a conversation when the line is busy, it does not appear that someone is trying to make a call or does not show as a missed call.

In the PBX settings and phones, I did not find such an item. Is it possible to fix this?
