Hi,
Read the linked web page with a growing sense of disbelief. In Australia, the UK and other ETSI ISDN countries, you can send whatever CID you like to the network, but if the CID is not registered to that PRI by the Carrier, it is rejected by the carrier and stripped off the call. This makes the kind of call spoofing described virtually impossible to do.
Similarly with "Blocked CID calls". If this is arranged with the carrier, the CLI is removed from the PRI data stream by the carrier and there in nothing that can be done at the receiving end to display it.
Intersting on how different markets have different standards on these issues.
