Siemens Highpath 3000

Hi, I have a Siemens Highpath 3550 Series pabx and getting error message B 20-17 !int. charg buf ovflw (system calls hang every few days over night - few calls after office hours) and the issue is clear after the pabx is power restarted. Any ideas what to check and where the fault may be. Thanks!

Charging buffer overflow is probably because there is call charging configured but the external connection to the call charging computer is disconnected

Thanks very much, I will check the connections.
