Try to move all of the traffic to another one wct4xpp card, and try to put this card with shared interrupts temporarily out of the box. Also: might be a good idea to disable software echo canceling. Note: i've have got very similar issues some years ago, but it was (that was suggested by Digium) a reason of using a clone card, not orginal Digium's. -------------- next part -------------- An HTML attachment was scrubbed...
