I have 4 digit extensions on my Panasonic KXTD500, but only 3 are coming through.
There was a bug in earlier releases of the Panasonic KXTD500 plugin.
You can download a corrected plugin from our website at:

You can also contact us at support@datatex.co.za
and we will e-mail you the corrected plugin.
As a last resort, you can change the configuration to accept 4 digit extensions,
by clicking on "Options -> FilePaths -> Configure" and change the length of the
extension field to 4.
