Can anyone tell me where I would look for open or default access passwords for my telrad digital 400 PBX? Our LD vendor called today and said we had billed over 3K in calls to Guantanamo last month. I don't beleive that they are originating within the building, as they are all through the day and night.
For now I have shut down international calling, but that is not a viable option for the long term as we have offices in Europe.

I think there must be some open access that I don't know about.

The system:
Digital 400 3 t-1's about 40 pots lines, version is PCP DB6.05

VM is also telrad 6.00D USA

Any thoughts on what I have done wrong? Whatever it is I think has been wrong for a long time and someone has just found it.

thanks
