Callers Log on Taurus sets M3903 and M3904 not updating
CLS must be CNDA and CPND must be configured
The M3903 model stores the last 10 incoming calls and the last 5 outgoing calls. The M3904 stores the last 100 incoming calls and the last 20 outgoing calls.
With a CLS of CNDD no calls will be stored.
The CPND data block must also be configured in LD95, or the sets will register outgoing calls but no incoming.
