Odd, I'm not aware of any current issues with Digium's cards or drivers which would leave it in an alarm state that wasn't attributable to an intermittent cabling issue. I've seen a loss of voltage between the tip and ring (assuming you're talking about FXO ports) due to cabling issues that would leave the card in alarm. If it's something marginal you could sometimes play with the battery threshold. I had seen some issues with the newer analog cards and stuck alarm states that were addressed in r7517 "voicebus: send 'idle' buffers when the transmit descriptor underruns" [1] which was first released in dahdi-linux 2.3.0. [1] http://svnview.digium.com/svn/dahdi?view=revision&revision=7517 If you still have the cards with which this problem occurred often, are able to reproduce it with the dahdi-linux 2.6.1, I would be interested in determining what the problem is. If you are interested and able as well, shoot me an email off-list. -- 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 -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
