Deciphering the Resulting Status Codes in RightFax

RightFax shows a status message for each fax in Faxutil and Webutil. To learn more about why a fax transmission may have failed, the fax history includes status codes that offer concise information. This Knowledge Base article helps to decipher these Resulting status codes.

Often, with failed faxes, information on the failure can be found in the transmission record for the fax.

Resulting Status Codes

RightFax shows the line status and the fax status for T.30 (PSTN) and T.38 (FOIP) fax transmissions. These status messages can be useful in analyzing fax errors and in helping to determine the nature of a failure (to assist with issue resolution).

However, these status messages, in conjunction with troubleshooting the telephony integration, can be useful in determining the nature of failures. As the success or failure of a fax transmission is entirely dependent on the telephony transport being used, these status messages can help to determine the underlying deficiency in end-to-end communication and can be used effectively to isolate an issue when combined with further troubleshooting and error reporting in the telephony network itself.

Interpreting the Resulting Status Codes

The fax history shows a Resulting fax status code. Both the first and second sets of numbers are gathered by the Brooktrout API to report on the call progress (reflected in the first set of numbers before the semi-colon) and the fax progress (reflected in the second set of numbers after the semi-colon).

A failure to send a fax using the server computer’s telephony integration can be generally classified into one of these two categories.

Call Setup Failures

Call setup failures occur when a call cannot be successfully placed to a dialed number. The first set of numbers can be helpful in determining call setup failures. This is especially true with Analog, Analog DID, BRI, and T1 integrations. For FoIP (either TR1034 ethernet enabled fax boards or SR140 “Boardless” fax boards), the Wireshark Network capture utility is considerably more useful for troubleshooting call setup errors.

First Set of Numbers – Call Progress Status

The first set of numbers represents the RightFax call status and the call line status. The first number is typically zero (“0”) and means that the call was placed. The second number can be found in Table 1 below.

Second Set of Numbers – Fax Progress Status

(This is generally where transmission failures are reflected.)

Transmission errors occur when a call is successfully placed from the fax server to the end point fax device (or from an end point sending device to the fax server), but the overall quality of the connection between the two end points is insufficient to convey the fax data effectively to or from the remote device.

The second set of numbers in the Resulting status code reflects the outcome of the fax transmission. This information does not yield any data about why a fax failed (that is, it does not indicate the specific reason why the communication between the two end points was unsuccessful). However, it does show what happened at the time that the fax failed.

For example, a Resulting status code of “0/339; 4/75” indicates that a DCN message was received from the remote device (a DCN is the signal sent from a t.30 device that states “I’m disconnecting”). This information indicates that the remote side terminated the call, but it does not indicate specifically why the remote side terminated the call. Therefore, since this information does not explain why the remote device terminated the call, it is more useful for identifying a behavior pattern, rather than for explaining the failure of an isolated fax call.
