one of our customers has a standalone CCM 6.1.2 server that logs exactly every 20 minutes a TspError message with an empty 'Name of Device'-field in syslog.
The messages look like this:
ccm: 50348: Dec 10 10:19:41.632 UTC : %CCM_CALLMANAGER-CALLMANAGER-3-TspError: Error in TSP. Port IsoEthPort:0 Port DSL:0 Name of Device: Cluster ID:StandAloneCluster Node ID:CCM-OF-CUSTOMER
I have had other similar syslog-messages that appeared more frequently but with an SEPxxxx as 'Name of Device' value. They where caused by a phone that permanently tried to register but was not in database and no autoreg enabled. That problem was easy to troubleshoot and solve. But with the message above I do not know where the problem comes from as there is no reference to the device.
Does anybody have an idea how to find the cause of the problem?
There are no Skinny-ATAs in the network and CPU usage is normal, but there are SIP-ATAs (used for T.38 Fax) registered as 'Third Party SIP Device'. Maybe the cause of the error message is a (second port of a) SIP-ATA that tries to register every 20 minutes. This could explain why the 'Name of Device' field in the error messages is empty.
