It sounds like the same problem that many of us have seen over the last several months. Digium support has been trying to identify the root cause and has been very quiet in terms of comments, etc. Replacing the little fxo/fxs module has apparently corrected the problem in some cases, but its fairly obvious the tdm card still has a problem that has not yet been diagnosed/fixed. Dropping/restarting the drivers is the only known fix (bypass) thus far. If you look back over the previous posts relative to tdm problems, you'll see lots of comments about ups's, power supplies, pstn lines, etc, etc. The majority of these have indicated the problem takes a fair amount of time (eg, days or weeks) before recurring, suggesting the problem might be related to a memory leak, temperature, or some other cause that involves 'time'. Shutting down an * system to install a ups, etc, disturbs just about everything associated with the intermitant problem. Jumping to a conclusion that a ups (etc) fixed a problem is essentially ignoring all of the other disruptions that happened during the ups install. _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
