[asterisk-users] Sangoma Card Issue

[Eric Wieling]

I switched to using Sangoma cards around 2003 or 2004 at my previous employer. My current employer was using Digium cards up to 2008 and had the issue.   We have no interest in switching back to Digium.  

I did not mean to imply that we had issues with current Digium cards, but re-reading my original message, I can see how I might have given that impression.

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.

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.
