FXO Line Not Detecting Busy Tone

[carlostico]

I have a FXO module installed in a Pika V2.0

Sometimes after a call, even if both parties hangup the call never ends, and the DAHDI channel remains busy until I soft hangup it or restart Asterisk manually

Sometimes just calling a number and getting a busy tone call doesnt end and reminds busy too.

How to tell Asterisk to hangup as it hears a busy tone or detects silence in both directions ?

Hello:

Same problem here, apparently the phone company provides remote disconnect supervision but nothing ,so tried to edit the DAHDI files without success. Any other alternative ? , what files to edit or how to implement this feature, its a must in our systems.

Greetings.

Try the changes below to allow the FXO ports to use tone detection as a source of disconnect supervision. This changes to loop start signaling and enables fast busy detection.

In '/etc/dahdi/system.conf':

# Span 1: FXS/1 "Pika FXS Board 1"
fxoks=1
echocanceller=WARP,1

# Span 2: FXO/2 "Pika FXO Board 2"
fxsls=2
echocanceller=WARP,2
fxsls=3
echocanceller=WARP,3
fxsls=4
echocanceller=WARP,4
fxsls=5
echocanceller=WARP,5



In '/etc/asterisk/dahdi-channels.conf:

; Span 1: FXS/1 "Pika FXS Board 1"
; Skip channel=1(FXS) -- freepbx option.

; Span 2: FXO/2 "Pika FXO Board 2" (MASTER) ;;; line="2 FXO/2/0"
signalling=fxs_ls
busydetect=yes
busycount=6
;busypattern=500,500
callerid=asreceived
group=0
context=from-pstn
channel => 2
callerid=
group=
context=default
...
<repeated for all FXO channels>

You may also need to uncomment and modify the 'busypattern' field for your specific country to match the fast busy cadence. Default is 500, 500.

Hi , tried your suggestions but still not working ...... is there any other setting to change ?

Could you collect a recording of the line? To do this:


a) At the Linux prompt through SSH enter the command below. This will stall the current SSh session.
dahdi_monitor 2 -r receive.pcm -t transmit.pcm
b) Next place a call through the Warp's first FXO port
c) When done press <Ctrl-c> to exit the monitor application over SSh
d) Then please retrieve the resulting *.pcm files from the Warp using scp. These files will be located in the same directory that the dahdi_monitor command was executed.

Correction - actually it is better to set the following parameters:


busydetect=yes
busycount=6
;busypattern=500,500


in /etc/asterisk/chan_dahdi.conf instead of /etc/asterisk/dahdi-channels.conf (which is included by chan_dahdi.conf). This is because dahdi-channels.conf file can be modified by the system.

Thanks

Try:

busypattern=200,200

[carlostico]

Try:

busypattern=200,200

Hi Mark i measure that audio a while ago and got the exact busy pattern too 200,200 but not success, for some reason the pika just doesn't distinct that
Have other pbx running same setup with no problems at all.......

Thanks
