First, the in s,3 you answered the line. If the fax machine doesn't answer on the first ring, it never will, because once asterisk picks up the line, there won't be any more ringing. Second, when s comes to an end, it will listen for a response, and be able to hear and respond to the fax tone. In this case, you hang up before that happens. So the fax extension can't be activated. > > Question is how does asterisk detect the call without answering? > I'm not wanting Asterisk to handle the call if it is a fax if possible??? > > I look forward to your input, > Thank You > > Barry > ___ > --Bandwidth and Colocation provided by Easynews.com -- > > asterisk-users mailing list > To UNSUBSCRIBE or update options visit: >http://lists.digium.com/mailman/listinfo/asterisk-users ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

However, if you can be flexible, many FAX machines have silent answer and includes a feature to ring the hand set if it determines the call is not for FAX. You may be able to find a model that allows ringing of an external phone set.

Your original plan should work if you can get Asterisk/Zaptel to do "silent answer" (in priority 2). Otherwise nothing is going to work. On the other hand, all Brother IntelliFAX support silent answer (something they call intelligent ring or the like). See if your machine has an TAD (telephone answering device) port - and old Brother I used had this. If yes, you can enable silent answer on the FAX, then connect your X100P/Asterisk to this TAD port. FAX machines usually monitors for FAX tone for 2 rings. Some machines also cut off ring to TAD before it determines it the call is not for FAX; if not, simply program your Asterisk to wait for a few seconds before doing anything. This should give you the same functionality. Yuan Liu Or can someone explain what make an incoming goto exten => s,.. and what make it go to exten => fax, How does this logic work??

As other replys have indicated, it's probably not possible, but have you
considered using spandsp & rxfax and have asterisk take the fax and email
it to you?
Crude (but currently working) example here:

RE: [asterisk-users] Dialplan checkup
Hi, As far as I understand, Fax detection works by the fax machine sending a specific tone down the line. Until the phone has been answered, there is no audio path so the receiving end cannot know what type of call it is. The stand-alone fax switch devices that appear from the calling end to work without answering actually answer the call then, if it's not a fax call, generate the ring signal for the phone themselves. The way it works with a Fax machine designed to work with a separate answering machine is either: The fax has an internal 'fax switch' function that generates a ring to the external device, or the fax waits for the answering machine to pick up the line, then 'snoops' the audio for the fax identification tony and takes over the call if it detects it. Either way, you cannot determine if it's a fax call without answering it. If your machine has a 'through' phone outlet for an answering machine (and the fax uses the snooping method of fax detection), you should be able to use this for the Asterisk trunk and as long as the Asterisk box *always* answers at some point, either via someone receiving the call or voicemail / IVR kicking in. Once the call is answered, the fax would be able to detect any tone on the line and take over if required, dropping the line out to the asterisk system.

How does Asterisk know to move from s,2, to either incoming,1, or fax,1,
The only jump I recognize it Goto(internal,incoming,1) which should take
all calls to incoming,1, and not fax,1,

The only jump I recognize it Goto(internal,incoming,1) which should take all
calls to incoming,1, and not fax,1,
In this particular installation (live & running), incoming calls from the
analogue cards end up in [incoming] so I use Goto to get them to
Goto(internal...) There is another incoming call source (an external SIP
account) which also just Goto's the same place.
So what happens then is that when asterisk answers the call, it will
listen for a calling fax machine - just like combined fax/phone machines
do. If it hears a fax tone, then it jumps to fax,1 in the same context,
otherwise it just carries on. It only does this if you have:
faxdetect=incoming ; Fax detection
in /etc/asterisk/zapata.conf
The jump to fax,1 happens "by magic", but I've found that I need 2-3
seconds to let asterisk "listen" to the incoming line for the fax
identifiaction beep. The down-side of this is that callers get 3
seconds of silence before the anouncement is made.
Have a look at this page for more:
http://www.voip-info.org/wiki-Asterisk+fax#SpanDSPSendingandReceivingFaxeswithAster
and then scroll down the the section headed:
Asterisk as a fax/voice switch
OT: is spandsp & rxfax handled by astlinux ?
I don't know - I build systems from scratch myself rather than use
astlinux, trixbox, etc. I had to compile spandsp (0.0.2) and patch-in
rxfax/txfax to asterisk 1.2.13. The instructions for doing this are on the
spandsp site - http://www.soft-switch.org/ not brilliant, but they got me
through (but I have had a great many years experience building &
installing software on Linux and other unix systems though)
But you could always run up a command line with asterisk -r and type in:
show application RxFAX
and see if it's supported... I get:
dsx*CLI> show application RxFAX
-= Info about application 'RxFAX' =-
[Synopsis]
Receive a FAX to a file
[Description]
RxFAX(filename[|caller][|debug]): Receives a FAX from the channel into
the given filename. If the file exists it will be overwritten. The file
should be in TIFF/F format.

Remember you are carrying an encoded analogue signal in digital form, so make sure you do not use a "lossy" codec (ie. G711 only) and while you or I may be quite tolerant of the odd click, and packet drop, an analogue modem signal (Which is what a fax communication is) is not tolerant at all.
