extending call history on a C600

[Guest sikittle]

hey

previously i've used the HKEY_CU\ControlPanel\Phone\CallHistoryMax setting to extend the number of entries in the call history.

On my C500 I set this to 5000 or something and had a list of calls for an entire year.

On my C600, the registry contained this key, but changing the value in there doesn't make any difference. It seems to be storing about a month of calls, which is approx 400 or so.

Does anyone know if there is a flag or another setting I need to use to get this to work?

Thanks
