Fax Detection problems

Asterisk Asterisk Support

Hi
In order to fax detection, I have enabled this option in inbound route and I receive fax without any problem.in addition to, I set one IVR and defined number 3 for fax and 2 for one extension.
The problem is when I get one call for that extension(caller inputed number 2), if I do not response to that call, the extension will ringing and not stop while the caller stop but the related extension is ringing!!!ringing ringing … until I pick up!!
This problem is only for FXS extensions not sip extensions.Sip extensions is hangup without any problem after caller stop calling.

Thanks for any help or guidance

I had a similar issues.

I solved enabling the busydetect=yes option in chan_dahdi.conf

Hi
Unfortunately with adding that line, I still have same problem!!
I put my chan_dahdi.config:[code][trunkgroups]

[channels]
context=from-zaptel
signalling=fxs_ks
rxwink=300 ; Atlas seems to use long (250ms) winks
usecallerid=yes
hidecallerid=no
callwaiting=yes
usecallingpres=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
canpark=yes
cancallforward=yes
callreturn=yes
echocancel=yes
echocancelwhenbridged=no
faxdetect=incoming
;echotraining=800
rxgain=1
txgain=1
callgroup=1
pickupgroup=1
;cidstart=polarity
;cidsignalling=dtmf
callprogress=yes

;Uncomment these lines if you have problems with the disconection of your analog lines
busydetect=yes
busycount=3

immediate=yes

#include dahdi-channels.conf
#include chan_dahdi_additional.conf
[/code]Of course there are another configuration files, dahdi-channels.conf and chan_dahdi_additional.conf, that I put them too:
