I did everything as you said, but nothing has changed. Activity is empty, no call logging. What do you mean by "custom field has some configuration"? I created and deleted this field several times with default settings.
I wanted to add to the above that when an incoming call comes from a new contact, a lead is created. But if this contact calls again, then nothing changes in the activity, it is empty.
No registration of incoming and outgoing calls.
