To ensure transparency and assist you in managing your expectations, we’ve detailed some country-specific limitations regarding the use of caller identification (CLI). Please review the following information carefully before making international calls.


  • Issue : International calls to Estonia using Estonian Skype number Caller Line Identifications (CLIs, also known as FIX numbers) may be blocked by our telecommunication partners.

  • Recommendation : We recommend checking back for future updates on this issue.


  • Issue : Calls to Norway may not go through if a Norwegian mobile CLI is used. This is due to specific regulations and technical limitations within the Norwegian telecommunications infrastructure.

  • Recommendation : Please consider using an alternative number or method for contacting recipients in Norway to ensure connectivity.

Australia (Telstra)

  • Issue : Starting February 19, Telstra will begin blocking any calls received at interconnection Points of Interconnect (POIs) that carry Telstra-held mobile CLIs. This measure is part of Telstra’s ongoing efforts to ensure compliance with Australian telecommunications standards.

  • Recommendation : If you are using a Telstra-held mobile CLI, you may need to explore alternative caller identification options to continue making calls to and from Australia effectively.
