[Asterisk-Users] Fax handled on E&M T1 DEBUG messages
Hello, I updated my test Asterisk box to CVS 01/12/2004 today and have seen the fax detected messages coming for every call that comes in over my E&M T1[B8ZS ESF]. This isn't a problem from a functionality standpoint(I have no fax devices), but I see these two lines show up in the DEBUG logs about every second of a live incoming call: Jan 12 11:32:18 DEBUG[229390]: DTMF digit: f on Zap/1-1 Jan 12 11:32:18 DEBUG[229390]: Fax already handled I have tried uncommenting OLD_DSP_ROUTINES in dsp.c and recompiling, restarting, but then the E&M lines are useless(the lines are there and are loaded, but no inbound/outbound calls go through) Any ideas? Thanks, MATT--- ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [Asterisk-Users] Fax Handled
On analog ports you need to Answer
Ringing
Wait,2
and then do something .
That should detect faxes.

Re: [Asterisk-Users] Fax Handled
Try adding:
exten => fax,1,Dial(blah)
Where Blah is the zap or SIP port your fax machine is connected to.

RE: [Asterisk-Users] Fax Handled
For PRI->*->fax over FXS It's as simple as having the fax extension the the incoming context associated with the PRI channels.

The last time I looked at the code, fax would only be detected if they
came in on a Zap channel. So if the fax was coming in on a SIP channel
then it would not work.

My extensions.conf are very simple. I have just one context for my trunk
connection, and the two sip endpoits.
extensions.conf
===
[globals]
TRUNK=Zap/g1
[sip]
exten => _0.,1,Dial(${TRUNK}/${EXTEN})
exten => _9.,1,Dial(${TRUNK}/${EXTEN})
exten => 710,1,Dial(SIP/client1)

I'm using G.711alaw.
My extensions.conf:
===
[globals]
TRUNK=Zap/g1
[sip]
exten => s,1,Background(demo-moreinfo)
exten => fax,1,Dial(${TRUNK}/${EXTEN})
exten => _0.,1,Dial(${TRUNK}/${EXTEN})
exten => _9.,1,Dial(${TRUNK}/${EXTEN})
Is this correct?

The CNG tones are sent by the sending fax machine, not the receiving
fax machine. Those tones are sent from the moment that the fax
machines dials and continues until either a timeout or the receiving
fax machine sends its synchronization tone.
How is your fax machine connected to the Asterisk machine?

Could please detail how can I do this configuration?
I dial from the fax machine and then, only press the "start" button, when the
destination fax machine answer me and send the fax tone. So, how could asterisk dial
trought the fax exten if the fax tone are sent only when the call is completed?

If your SIP link is over a long line, or that has much in the way of variable latency, then this will just have to be expected behavior. The problems listed above are not unique to asterisk but the VoIP traffic trying to carry modem call. You would be better off using a network fax gateway that accepts the image to be faxed for you.

Hello, Is there any configuration in zapata.conf for fax detection (or transmission)? When I try to send a fax trought asterisk, the line 'Fax Handled:' is always set to "no". The scenario is: [ata186]---sip---[asterisk]---e1 E&M---[pstn] Fax sometimes goes without problem and sometimes the fax machine can't send the fax.

Okay, that's the problem. Asterisk does not detect faxes while
executing the Dial() application. You need to Background() a simple
greeting (or just 2-3 seconds of silence) before executing the Dial()
application, then provide a fax extension for Asterisk to jump to upon
detecting the CNG tones.

Re: [Asterisk-Users] "Fax Handled: no" config
I doubt it's a signal loss problem. It's a simple circuit, connected through our local Meridian, so it's fax-to-Meridian [A] Meridian internal [D] Meridian to Channel Bank [A] Channel Bank to Asterisk [D] And I know that the fax works okay; it's a production unit that gets used every day. As for the conf's, I've tried several things. Here's my best guess so far: from zapata.conf: context => incomingfax channel => 47 and from extensions.conf: [incomingfax] exten => s,1,Answer exten => s,2,Wait,18 exten => s,3,Goto,incomingmain|s|1 ; roll to main exten => fax,Dial,Zap/3 Fax calls are answered, then * waits 18 seconds (while the fax machine is beeping) then * rolls the call to incomingmain|s|1.

I know there was discussion at one point of signal loss through multiple d/a and a/d conversions what speed does it connect at through the extension ?

Re: [Asterisk-Users] "Fax Handled: no" config
It's dynamically changed to "Yes" when the fax gets detected on this channel. regards Martin On Wed, 12 Mar 2003, Darrell Eldridge wrote: > I still haven't been able to get fax detection going, > but I came across something: when I execute "zap show > channel 47" one of the parameters shown is "Fax > Handled: no".

Re: [Asterisk-Users] "Fax Handled: no" config
Fax handled will be set to yes when zaptel detects the fax CNG tones on the line. At that point it will try to switch the call to the fax extension James On Wed, 12 Mar 2003, Darrell Eldridge wrote: > I still haven't been able to get fax detection going, > but I came across something: when I execute "zap show > channel 47" one of the parameters shown is "Fax > Handled: no".

[Asterisk-Users] "Fax Handled: no" config
I still haven't been able to get fax detection going, but I came across something: when I execute "zap show channel 47" one of the parameters shown is "Fax Handled: no". I assume that's a reflection of something in zapata.conf, but I don't find anything there. Should it read "...yes" in order for Asterisk to detect the fax tones? If so, what's the syntax for setting it to yes? __ Do you Yahoo!? Yahoo!
