Call to UK numbers blocked
I have a UK number from Zadarma, I have connected it to VAPI (added the SIP Trunk Credentials and imported the phone number).
When I tested it calling a Greek number from this phone it worked as expected. (example call ID: bc24e9bd-6423-4e6b-89a0-c68d5c5f7734)
When I made a call to UK numbers it always ends receiving this automated message from user: "These calls are only possible within the country." (example call ID: bf70d462-c62c-4e0f-9021-594cbc98c163)
How can I fix this?
