Asterisk status code

Overview

Asterisk code 정리.

Originate result

원문은 이곳<ref>https://wiki.asterisk.org/wiki/display/AST/Hangup+Cause+Mappings</ref>에서 확인할 수 있다.

Originate 를 하게 되면(cli: Dial()) Originate 에 대한 결과를 받아오게 된다. 성공, 혹은 실패. 그리고 실패에 대해서는 왜 실패했는지에 대한 사유가 있다.

Channel status

Asterisk 에서 관리되는 모든 채널들은 다음 중 하나의 상태를 가진다.

• 상태 코드 정의

0부터 시작한다. <source lang=c> /*!

* \brief ast_channel states
*
* \note Bits 0-15 of state are reserved for the state (up/down) of the line
*       Bits 16-32 of state are reserved for flags
*/

   AST_STATE_DOWN,             /*!< Channel is down and available */
   AST_STATE_RESERVED,         /*!< Channel is down, but reserved */
   AST_STATE_OFFHOOK,          /*!< Channel is off hook */
   AST_STATE_DIALING,          /*!< Digits (or equivalent) have been dialed */

Device status

Asterisk 에서 관리되는 모든 디바이스(Device)들은 다음 중 하나의 상태를 가진다.

• 상태 코드 정의

0부터 시작한다. <source lang=c> /*! \brief Device States

*  \note The order of these states may not change because they are included
*        in Asterisk events which may be transmitted across the network to
*        other servers.
*/
