Dahdi busydetect does not work

General Help
1

Hi,

I’ve installed AsteriskNOW with Asterisk version 1.6.2.23 with FreePBX version 2.10.1.4. I’m using dahdi with OpenVox A1200P card for 4 analog lines (I have past successful experience with that).

Everything works fine: I can dial out and in. Seven internal extensions are connected and fully operational. However, there is one major problem and that is the “busy” signal is not being detected! It causes, of course, many problems (trunks stay open, rendering the system with no free lines, voicemails are becoming enormous, etc.)

As I have experience with that, I’ve set in chan_dahdi.conf:
busydetect=yes
busycount=3

but, it looks like the system ignores this.

I’ve restarted the services, then rebooted the entire server, then disabled the Dahdi config module in FreePBX. Nothing helped!

Can anyone help me with that?

busydetect is your last resort when all other disconnect options with your telco are unavailable or you are stuck with “ground start” FXO’s.

If they can’t or won’t provide “disconnect supervision” (battery disconnect usually for 500 ms. ), you could try

hanguponpolarityswitch=yes

as some locales use that methodology instead.

Without

busypattern=500,500 ;in milliseconds

any repeated pattern of tone and no tone repeated busycount times will hangup your hardware (well, at least it WILL hangup legitimate Digium hardware :wink: ), busypattern allows more selectivity and fewer false hangups caused by forklift trucks backing up. You can measure indirectly the tone cadence sent by the Telco by using dahdi_monitor to send the audio stream to a file.

p.s. As many might point out your choice of AsteriskNow and Asterisk 1.6 is probably not the wisest ones to make, I suggest youi start over with a more functional and modern distribution. As you are here, try the Schmooze/FreePBX one linked to from this very page.

Thanks for the tip, but did not make any difference. I did what you suggested, while keeping only the
hanguponpolarityswitch=yes

without the previous settings, but it did not change the outcome.

I suspect that the chan_dahdi.conf is not being parsed by the system for some reason. I understand your point, but still, even if busydetect was a bad choice it should have been performed, like the hanguponpolarityswitch=yes.

Any other thought of how I can resolve this?

You can verify settings by doing a ‘dahdi show channel xx’ where xx is the output of the ‘dahdi show channels’ command.

Who is the provider (are these ilec lines from a cable company perhaps).

Are you using the Openvox DAHDI drivers? Does it have an exclusive irq, check via lspci command at Linux shell.

Here are the settings of channel 1. I got same responses for the other channels.

As for your other questions:
The provide is Bezeq (The Israeli leading provider). Lines are analog. Don’t know if they are ilec, but it is not a cable company).

Card is OpenVox A1200P. I had an identical configuration with the previous machine (I am just upgrading it now), and there the busydetect worked perfectly.

lcpci -vvv output is here:

sorry, I missed the essence of your question above. Checked the IRQs:

lspci -vvv | grep IRQ
Interrupt: pin A routed to IRQ 10
Interrupt: pin A routed to IRQ 58
Interrupt: pin A routed to IRQ 225
Interrupt: pin B routed to IRQ 233
Interrupt: pin C routed to IRQ 217

Interrupt: pin A routed to IRQ 225
Interrupt: pin A routed to IRQ 217
Interrupt: pin B routed to IRQ 233
Interrupt: pin B routed to IRQ 233
Interrupt: pin A routed to IRQ 50
Interrupt: pin A routed to IRQ 177

the last one belongs to the a1200p.

Do you have your localization set?

Please post contents of all files in /etc and /etc/asterisk that contains the string dahdi in the filename.

Restart Asterisk with amportal restart then grep /var/log/asterisk/full for the string dahdi occurring at the time of restart.

Ok, you set the busydetect however it is redeclared to no later on in the /etc/asterisk/chan_dahdi_additional.conf file.

I would remove all the includes from /etc/asterisk/chan_dahdi.conf except the dahdi-channels.conf

Once you do this the options you set in chan_dahdi.conf will have effect.

You do not need to restart asterisk, reboot or any other foolishness, simply execute the command ‘dahdi reload’ from the asterisk cli.

That solved this. Thank you very much.
