[asterisk-users] dahdi channels busy/congested
Dear all,
i have a problem with a system running
- Ubuntu 10.04 ( all updates done )
- ii asterisk 1:1.8.5.0-1digium1~lucid Open
Source Private Branch Exchange (PBX)
- ii asterisk-dahdi 1:1.8.5.0-1digium1~lucid DAHDI
devices support for the Asterisk PBX
I also use freepbx 2.9 for the configuration.
Hardware is a Dell R410 and a Digium Wildcard
wcte12xp+ d161:8000 Wildcard TE121
The status is as follows,
- all drivers are loaded and the E1 card shows a GREEN LED and no alarms
- asterisk is up
- the provider is Bharti Airtel in India
- the configuration was copied from my PBX in germany and slightly modified,
that is a asterisk 1.4 though

Any hints or ideas for me ?

So I'm not quite sure. My best guess is that there is some issue with how the package was created (especially given the old version of DAHDI reported with then 1.8 branch of Asterisk). Is there any DAHDI related output in 'dmesg'? What is the output of "pri show channels" on the asterisk command line? Are you able to install from source? -- Shaun Ruffell Digium, Inc. | Linux Kernel Developer 445 Jan Davis Drive NW - Huntsville, AL 35806 - USA Check us out at: www.digium.com & www.asterisk.org
