I ran CCS trace one of our switches and noticed the following line
10:31:21 RI62 DAS 1A CRM/CIM ;9;*AA*LINE OUT OF SERVICE#
I checked the state of the trunk and it reports idle or busy with a call in progress. Has anyone seen this and can explain why it should do this, I haven't seen it before. Other trunks on this card show the same message but all trunks continue to take calls.
The system is MS2009 F-UK-00 edition SX.Q23.2.5
