It is really frustrating to not have incoming CLI from International numbers.
On my mobile handset I receive international CLI, but not my BT Wireline, even though CLI is enabled. All it shows is "International" so I do not know if the call is a customer, or less important call.
The only comment I have had from BT and have seen in this forum is "CLIs from International calls will only be provided on 64kbp/s data calls where BT has Commercial agreements with the corresponding country" and "CLIs are not provided on International speech calls".
This is not an issue of individuals withholding numbers, the information is in the network (otherwise I would not see it on my mobile) it's just not presented to my handset. Furthermore those I call see the CLI from myself. Please support this message if you wish to see it provided... otherwise I'll just go into a corner and keep quiet!
