For those
who use ISDN I suggest implementing the current modification to improve alarm
logging
//
Dialogic/drivers.cpp Improvement in alarm
logging.
// Now we
can tell in the log witch T1/E1 as experienced an alarm like bad
clocking
//This error indicate a problem in the Dialogic layer it should a least be
reported

slog(Slog::levelError) <<

// this needs fixing, we should
find the right span involved
// This is the fixed version

for(span = 1;
span <= getSpanCount(); span++)
{
isdn = getSpan(span);

sr_getevtdev())
