This read-only integer reports the total count of fax calls handled by this port, complementing totalFaxUsage's time figure. Admins divide totalFaxUsage by faxcount to get average fax session length, useful for distinguishing normal fax transmissions from repeatedly failing/retrying fax attempts. For example, a rising faxcount with disproportionately low average duration per call could indicate fax transmissions repeatedly failing to complete and retrying.
