This patch has been extensively tested and proven to be very stable for receiving of Faxes. We have bulk tested this patch sending various amounts of Faxes with different pages ranging from 2 to 30 pages at random. We have also stressed the 3CX Fax Server sending 1 large fax of 120 pages that took 21 minutes to transfer and it was received and processed with success. Stress tests included sending 1000 faxes with random pages over a period of 7-8 hours (depending on the fax pages sent) sending approximately 2 faxes every minute from different fax machines.Memory usage was constant between 30-40 MB. CPU usage during bulk test was between 0-3%
