Junghanns QuadBri install help

Hi,

I have a Junghanns QuadBri installed and seems to be detected and working correctly using the wcb4xxp driver
All ports are configured as TE

The problem is when I connect an ISDN line - the LED turns green and Dahdi status shows Alarm OK
But when I try to make a call I get “All circuits are busy” cause 27

I have searched the web and tried numerous configs but it doesn’t want to play.
I can accept incoming calls but there is no Audio which would indicate an issue with the driver wcb4xxp?

See config files below and dahdi commands - please ignore that RED alarms there was no ISDN lines plugged in.
I contacted Junghanns but still waiting on response.

Thanks, Joe

Here is CLI from a call

Answered via -users mailing list, I believe. Will move to SOLVED.

Hi Malcolm

Reason 27 was explained but I wouldn’t call is solved

Here is my reply on the Users mailing list


I have a Junghanns QuadBri installed and seems to be detected and
working correctly using the wcb4xxp driver
All ports are configured as TE

The problem is when I connect an ISDN line - the LED turns green and
Dahdi status shows Alarm OK
But when I try to make a call I get “All circuits are busy” cause 27

PRI_CAUSE_DESTINATION_OUT_OF_ORDER 27

The network does not think who you are calling is functional.

Richard


Thanks for that - so its the Telco or ISDN equipment causing the issue?

Here is a pic of the box the ISDN terminates: bit.ly/Af6jp6
(There are 3 of these units)

The boxes seem to draw some power from the connection but also accept a
power via a plug.
Maybe I should just plug them into the main power - What do you think?

The ISDN’s are in use in an old Toshiba PBX so are 100% functional.
I can call the Telco but not sure what I can ask them to do.


Just posting here incase someone has any feedback.

Thanks, Joe

It turned out to be the power to the ISDN boxes - They fail back to single line mode when there is no mains power supply.

Working perfectly now.
