I have upgraded snom 300 & 320 to version 7 (7.1.30 ), after upgrades I no longer see call history - missed calls, received calls and dial calls. Afer an incoming or outgoing calls when I go into the call history to review it display "no data available". I further upgrades to 7.1.33 and the results are the same - still no missed calls, received calls and dial calls data
