The UK is the clearest case. Since 29 January 2025, Ofcom expects providers to block calls arriving from outside the UK that present a UK number as the Presentation Number, with a narrow set of exceptions. In July 2026 it published a decision extending the approach to UK mobile numbers.
If you service or collect from a hub abroad, that changes what a caller ID is. Set one in a softphone and the call can be blocked outright, or delivered with the number withheld. Neither reaches the customer.
The fix is structural rather than clever: originate the call in the country whose number you present, on numbers held in your own account, through a provider licensed in that market.
- Numbers you hold, not numbers you assert
- In-country origination on local media gateways, rather than looping back through a regional hub
- Licensed local voice in selected markets, delivered under a national carrier’s license
- One account across countries, instead of a separate local contract in each
