A strange thing is happening to one of the ISDN PRI Line. This problem is not happening on the other ISDN PRI line.
This router has 2 ISDNs - PRI 30 channels from Carrier 1 and 20 Channels from carrier 2.
I have done a test during my investigation.
When I turn on the ISDN - PRI line from Carrier 2, it automatically dials itself to many different countries. When I turn it Off, things are fine.
I have shut the PRI- ISDN from Carrier 2 now to prevent massive phone bill, so the users will have to depend on Carrier 1's ISDN PRI for the time being. I have checked all of the configuration.
In addition to show tech, I have posted another file called Investigation Monitoring with some debug outputs.
0011 is the International Country Code to dial out of Australia to any other country.
Open the Investigation Monitoring with wordpad.
