My case:
After restart (and some other time too) on an asterisk server I get these
warnings every 10s on span 1. Another time (I did not see that at the same
time together) every 35s on span 2. Both lines are to the same telco
operator. No warnings on span 3 or 4, lines to older PBX (asterisk server
is in NT mode for span 3 and 4).

After a call is placed on the line to telco operator (the line that
generates warnings, the direction of the call does not matter) warnings
stop and all is OK. It may be after hours. There is no alarm all the time.

heruan, so I think these warnings are not necessarily the cause of your
RED alarm.

To be sure: did you test span=2,0,0,ccs,ami for NT mode?
