Summary:                    app_fax.c: Transmission error for successfully
transmitted faxes
Description: 
Sometimes application SendFAX indicates "app_fax.c:817 transmit:
Transmission error" even the transmission of FAX was successful "app_fax.c:
Fax transmitted successfully". I figured out it happens because res value
in loop is set to 4 (probably because remote party hangs first?).

I am not sure if the problem is bug or just not expected behavior of
SendFAX application. Because in following scenario external application
will not be notified:

exten => s,1,Noop()
exten => s,n,SendFax(${FAXFILE})
exten => s,n,System(/opt/fax/notify.py "${FAXID}" "${FAXSTATUS}"
"${FAXERROR}")

Workaround is to use "h" extension to catch transmitted faxes with any
result.

exten => s,1,Noop()
exten => s,n,SendFax(${FAXFILE})
exten => h,n,System(/opt/fax/notify.py "${FAXID}" "${FAXSTATUS}"
"${FAXERROR}")

Maybe similar option like "g" in Dial application would be nice in SendFAX
application... or at least note in documentation :-)
