I have noticed an issue with outgoing international calls from my Sunrise number. When I call mobile numbers in Greece, the people I call do not see my real phone number. Instead, they see random or incorrect numbers on their screens.
This problem happens every time I call Greece, but not when I call numbers within Switzerland.
Could you please check if the Caller Line Identification (CLI) is being transmitted correctly for international calls? It seems that the CLI passthrough may not be working properly.
I would appreciate it if you could make sure that my correct number is displayed to recipients in Greece.
