Hi everyone.
We are trying to configure a system to send faxes using iaxmodem, hylafax and asterisk but we are not able to send faxes. We have the following configuration.
IaxModem service configuration:
CountryCode: 34
AreaCode: 91
FAXNumber: +34.91.987.56908
LongDistancePrefix: 1
InternationalPrefix: 011
DialStringRules: etc/dialrules

RecvFileMode: 0600
LogFileMode: 0600
DeviceMode: 0600
RingsBeforeAnswer: 1
SpeakerVolume: off
GettyArgs: "-h %l dx_%s"
LocalIdentifier: "NothingSetup"
TagLineFont: etc/lutRS18.pcf
TagLineFormat: "From %%l|%c|Page %%P of %%T"
MaxRecvPages: 25
ModemType: Class1 # use this to supply a hint
ModemResetCmds: "ATH1\nAT+VCID=1" # enables CallID display

Class1TMConnectDelay: 400 # counteract quick CONNECT response
CallIDPattern: "NMBR="
CallIDPattern: "NAME="
CallIDPattern: "ANID="
CallIDPattern: "NDID="
The modem has this configuration:
device /dev/ttyIAX0
owner uucp:uucp
mode 660
port 4570
refresh 60
server 127.0.0.1
peername iaxmodem
secret password
codec alaw
In /etc/asterisk/iax.conf
[general]
bindport=4569

type=friend
secret=password
port=4570
host=dynamic
context=fax-out
disallow=all
allow=alaw

In chan_dahd.conf, we have:
[general]

overlapdial = yes
switchtype = euroisdn
signalling = bri_cpe_ptmp
channel => 1-2
context = default
group = 63

echocancel=yes
echocancelwhenbridged=yes
group=1
callgroup=1
pickupgroup=1
busydetect=yes
busycount=10
faxdetect=both
In extensions.conf file we have the following rules for fax-out
[fax-out]
exten => _X.,1,Dial(dahdi/1/${EXTEN},,r)
exten => _X.,n,Hangup()
The services are running without any problem.
asterisk
hylafax
iaxmodem
faxgetty
When we try to send a fax with this sentence "sendfax -n -d 91XXXXXXX /var/spool/fax/test.pdf" we get the following error.

If we try the previous sentence with +34 (prefix of Spain), the error change and these are the files:

We don´t know if we are missing or mistaking something in any configuration file or any other issue.
Please, send help!!!
Thank you very much in advance.
This (NO CARRIER) means that the modem was unable to detect any fax receiver on the channel after the call was placed even though the call was answered. In other words, either you're not calling to a fax receiver or the call is not getting through for some reason. Bottom line: the issue is either with the number dialed or with your Asterisk configuration.
The "hangup request, cause 102" is a clue. That means "RECOVERY_ON_TIMER_EXPIRE". So something is, indeed, wrong with your Asterisk dialplan or configuration or with your telco service provider.
Probably the best course of action would be to work with your telco for assistance.
