Hello,
Trying to set up res_fax_spandsp. Based on
https://wiki.asterisk.org/wiki/display/AST/T.38+Fax+Gateway I wrote this in

same => n,Set(FAXOPT(gateway)=yes)
same => n,Dial(DAHDI/3) ----->FXS port to fax machine
same => n,Hangup()
Call flow Im trying to pull out is as follows:

ReceiveFAX issue.
I am testing out inbound faxing using res_fax and res_fax_spandsp.so
My system answers the call but then sets there on the ReseiveFax line then
comes back with an error that it exceeded the maximum retries.
How would I go about debugging this? Below is my very simple dialplan code
I am using, and the fax show version gives the following as well.

res_fax
I am working on some fax tools for some of my users. I am reading the
https://wiki.asterisk.org docs for faxing.
Is see Application_SendFax and Application_SendeFax has one been
discondinued? Any feed back on using the res_fax module would be
apperciated. Any examples or other.
Thanks
Bryant

FAX CNG detected but no fax extension
Hello,
I have a question regarding incoming fax to local file (on the Asterisk server).
While the fax is received properly (I have the tiff file generated as expected) I get the warning 'FAX CNG detected but no fax extension' on the consol.
If the fax is received ok then what 'fax extension' does it expect and what should I do there?

AMI status events with res_fax_spandsp.so
Is anyone else using the AMI with res_fax_spandsp.so for real-time status?
I am working on migrating a FAX application from res_fax_digium.so to res_fax_spandsp.so. I have noticed that the spandsp module generates far fewer AMI status events than the Digium module and the generated events contain less information. For example when sending a fax there is no longer an event for every page. There

Receiving faxes with spandsp question
Hello!
I?m trying to add fax functionality to my asterisk installation. Right now I?m focusing on receiving faxes. This is not explained in a book, but I assume that I can use same context, add ?fax? extension and if someone calls to send fax - it will autodetect. Right?
Per book, I made following setup additions:
1. In sip.conf [general] I added:
;FAX stuff
faxdetect=yes
t38pt_udptl=yes

Anyone have a reliable T.38 Solution
Aloha,
We are looking to roll a solution that will have the following network layout:
ISDN-PRI <--> Asterisk <--> T.38 <--> ATA <--> Fax
Does version 1.8 with the Digium fax driver have this capability? I
like 1.8 because it is a long term support version.
What ATA's are people using?
Any working solutions would be great!
Aloha,

We are using res_fax_digium with a Sangoma PRI card on asterisk 1.8.13
The docs at http://docs.digium.com/FAX/fax_for_asterisk_admin_manual.pdf indicate v34 is supported, but when I enable it I get the message "res_fax_digium.c:1624 dgm_fax_new: V.34 not supported, will be ignored." Is v34 only supported with SpanDSP?
Also, the res_fax.conf.sample does not indicate v34 as a valid

we're trying to setup a fax gateway from PRI to SIP. Our test setup
consists of two asterisk 10 machines connected over PRI and a third one
which is acting as a fax endpoint over SIP.

Problem compiling res_fax_spandsp.c on Debian server.
Hi everyone.
We have an Asterisk server running Debian Squeeze, with Asterisk
v1.8.13.1 (basically, the Debian Stable version for Squeeze, but with
some minor source code changes specific to our site). We're trying to
upgrade to 11.13.1 (The Debian Stable version for Jessie), but I've run
into a snag when compiling res_fax_spandsp (and yes, we really need that

ReceiveFAX G.711 + Realtime
Hello,
We're trying to receive G.711 (aLaw) faxes on the asterisk and convert
them to tif. With T.38, we have several issues, so we are trying to use
G.711, since the gateway is located in the same LAN, so there's no
bandwidth/packet-lose issue.
We also use on the same Asterisk Real-Time process for the extensions.conf
My question:
Is the following syntax for disabling T.38 support

Fax throughput - Asterisk 1.6.1.9
Hello,
We are trying to send faxes by T.38 protocol to a remote SIP proxy from
a local extension. The local extension sends the INVITE, Asterisk sends
the call to the Proxy the call is connected with a regular audio codec.
After a few seconds the remote proxy sends an INVITE with UDPTL and the
Asterisk sends it to the local extension and it's accepted, but (here
the problem starts) just

Sending faxes with T.38 problem. Fax for Asterisk (no SpanDSP) - 1.6.1.1
I am testing Fax for Asterisk. But, I meet a problem. I try to Send a Fax (.tiff) from the first
asterisk (Asterisk1) to the second asterisk (Asterisk2). Asterisk1 initiates an INVITE with audio G.711. Asterisk2
accepts this INVITE. Immediately, Asterisk2 sends an re-INVITE with T.38 to Asterisk1. But, Asterisk1 responds with
"488 not acceptable here". I double check t38pt_udptl = yes in
