I'm hoping someone can help with an issue that has arisen with my bt6510 handset. Up until 3 weeks ago the phone would show a list of who had called and the time using the calls list function. But now when you go to calls list all the numbers in the list are 000000000000 with a time of 0.00am.
The manual only says you must subscribe to a caller display service for this feature but sheds no further light on the issue. Our package with the network provider has not changed for months so I don't believe that can be the problem and when incoming calls come in the details are shown on the handset.
Can anyone shed any light on this issue please.
Solved! Go to Solution.
Have you tried turning off the power to the base unit for about a minute?
If its just one handset causing the problem, then take out the batteries for a couple of minutes as well.
Who provides your phone service?
Excellent 😀
Sometimes the communications between the base and handsets gets corrupted, so a power cycle resets it.
