Fax Error Message: Answer detected probable human
Fax Expert Reply: A human picked up the fax line or interrupted the fax call and it did not go through on final fax retry. Most likely someone picked up at the other end or the number may no longer be in service as a fax number. If you find that this same error happens and it works to send a fax to this recipient by using another type of telco service, you can contact Support to provide the sent fax detail (your fax number, the fax number you sent to (including country code if applicable), and the date/time sent. Then support team can escalate to eFax developer team to test further and provide more feedback back to you.
