Asterisk hangup code

Overview

Asterisk hangup code 내용 정리.

Basic

Hangup cause 코드 정리. Asterisk 는 Hangup code로 ITU-T Q.931 을 준수한다. Q.931과 SIP 코드와 매핑을 하기위해서는 RFC 3398 을 참조하면 된다.

/*! \name Causes for disconnection (from Q.850/Q.931)

Retry

Dialing 시도가 실패할 경우, 리턴 코드에 맞춰 재시도를 해야 할 경우가 있다. 임의로 만든 Retry table. 아직은 사용하지 말 것.
