CLI
Local Korean numbers cannot be used as the CLI to send traffic towards South Korea unless you purchase dedicated Korean number from Vonage.
You cannot add a plus sign (+) to CLI.
When calling from overseas, callers should see the international telephony carrier’s prefix and calling number, for example, if US number 14155551212 is calling a South Korean number, CLI added with a prefix shows up as 006 14155551212.
Prefixes for different carriers:
- KT 001
- LGU 002
- SK Telink 006
