A few weeks ago, we installed a UC540 system for a customer with the SPA 509 ip phones. The customer has 3 Analog lines connecting to the FXO ports to connect to the PSTN. Caller-ID is enabled on the ports. When a call comes in from the PSTN, the phones display the correct Caller-ID (name and number) and time of the call. But when the phone user checks the Missed Calls, Placed Calls list on the IP Phone, The date is off by exactly 6 days ahead. The hour and minutes are correct, by the date is not. Yesterday (8/24/2010) I made test calls, and the date under the Placed Calls list had the date as 8/30/2010.
The clock is correct on the router, time displays properly on the phones. The voice call history on the UC500 shows the correct date and time.
Is this a Software bug on the phone loads or IOS?
Anybody run across this?
