•Minimum length of phone number indication an external call - this is the main configuration setting to determine if a call is internal or external

•Activate the Desktop Notification window for outgoing calls to get each call signaled

•The configuration option: Don't show internal calls must be unchecked to trace the call in the Desktop Notification window

•If the internal number is e.g. signaled with 12 but the number stored in the database is 07342/7383-12, see in Prefix for Internal Numbers how to add the company number and area code
