Outgoing Phone Calls not in log.nsf

Hello, my Domino Server don’t write the outgoing phone calls immetiatly to the log.nsf. It takes two days or more. If I restart the server most of the documents appear.

After that the documents have different create and change dates and times. The create date and time ist the same like the time of the phone call and the change date and time is the date and time of restart.

Thanks for yout help.
