>          Issue Type: Bug
>          Components: Applications/app_fax
>            Reporter: Jan Klepal
>            Severity: Minor

> 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:
> {noformat}
> exten => s,1,Noop()
> exten => s,n,SendFax(${FAXFILE})
> exten => s,n,System(/opt/fax/notify.py "${FAXID}" "${FAXSTATUS}" "${FAXERROR}")
> {noformat}
> Workaround is to use "h" extension to catch transmitted faxes with any result.
> {noformat}
> exten => s,1,Noop()
> exten => s,n,SendFax(${FAXFILE})
> exten => h,n,System(/opt/fax/notify.py "${FAXID}" "${FAXSTATUS}" "${FAXERROR}")
> {noformat}
> Maybe similar option like "g" in Dial application would be nice in SendFAX application... or at least note in documentation :-)
