Temporary issue detected with Phone feature

The temporary issue has been resolved, and the service is now fully operational. We apologize for any inconvenience this may have caused.

- Incident Time: October 23, 2026 10:40 ~ 17:50 (KST) (approximately 7 hours 10 minutes)
- Affected Scope: In phone consultations received through SKB lines (including 070 numbers issued by SKB), agents heard the customer's voice cutting out. Call connections and lines from other carriers were not affected.
- Cause: A network issue on the carrier (SKB) side caused customer audio to arrive delayed and out of order, resulting in parts of the customer's voice being lost.
- Resolution: We applied an emergency measure so that delayed audio would not be lost. After SKB completed its recovery at 17:50, the temporary measure was reverted to its original state.

We will continue to strengthen monitoring to prevent similar issues from occurring again.

Temporary issue has been detected with Phone feature. We are currently investigating the cause and will provide updates shortly. We apologize for any inconvenience this may cause.

- Affected Scope: Phone calls on channels using SKB 070 numbers
- Cause: An issue on the carrier's (SKB) side is causing customer voices to cut out during calls
- Resolution: We will apply the measures available on our side by this evening. Even after these measures, customer voices may be heard with a slight delay. A full resolution will be completed once SKB resolves the issue on their end.
