Hi,

Thanks for the link. I looked at that page but couldn't see how it
helped with my specific issue, unfortunately, though I admit I'm fairly
new to asterisk so I don't fully understand what's going on.

In our application it's the dialled number that decides whether to jump
to the recvfax priority, hence all numeric extensions starting with zero
being allowed.

This is what I've got in extensions.conf for receiving faxes (as a test
I added a few specific extensions "f" and "fax" to the end of the
recvfax context but those lines never get executed):

[recvfax]
exten => _0.,1,SET(__channel2=${UNIQUEID})
exten => _0.,2,AGI(service_nts_nextgen|answered|${channel1}|${channel2}|7)
exten => _0.,3,Set(INIT_EXTEN=${EXTEN})
exten => _0.,4,Set(__FAXFILE=/var/spool/asterisk/fax/${STRFTIME(${EPOCH},,%Y%m%d%H%M%S)}-${CALLERID(num)}-${INIT_EXTEN})
exten => _0.,5,SET(CALLERID(name)=${FAXFILE})
exten => _0.,6,Dial(IAX2/iaxmodem0/${INIT_EXTEN})
exten => _0.,7,Dial(IAX2/iaxmodem1/${INIT_EXTEN})
exten => _0.,8,Dial(IAX2/iaxmodem2/${INIT_EXTEN})
exten => _0.,106,NoOp("test2")
exten => h,1,System('/var/lib/asterisk/agi-bin/fax2email.pl --source-file "${FAXFILE}.tif" --format "${fax2email_format}" --paper-size "${fax2email_paper_size}" --email-to "${fax2email_to_addr}" --email-from "${fax2email_from_addr}" --email-from-name "$
{fax2email_from_name}" --cli "${fax2email_cli}" --dni "${fax2email_dni}"')
exten => h,2,deadAGI(service_nts_nextgen|completed|${channel1}|ANSWER|${UNIQUEID}|0)

exten => fax,1,NoOp(fax extension)
exten => fax,2,Hangup

exten => f,1,NoOp(f extension)
exten => f,2,Hangup


This is what I get in the asterisk log (I've just extracted what I
thought was the relevant bit to keep this email short):

[Jan 25 16:42:31] VERBOSE[3493] logger.c:     -- Channel 0/28, span 2 got hangup request, cause 16


When my friend sends a fax that works, I don't get the "Detected digit
'f'" line in the log. Not sure whether that suggest anything?
