DP: 客製內建的 on demand recording (*1)

停用內建的 on demand recording

如果有使用 FreePBX，停用此功能必須使用 Web UI 操作
FreePBX Admin > Feature Codes

In-Call Asterisk Toggle Call Recording: Disabled

沒有安裝 FreePBX 時
編輯/etc/asterisk/features.conf

...
[featuremap]
;automon=*1 ;將這行註解

確定 Dial Command 沒有 wW 參數
FreePBX Admin > General Settings > Dialing Options

Asterisk Dial command options:
Asterisk Outbound Dial command options:

檢查設定

#asterisk -rx "features show"

Builtin Feature           Default Current

新增一個 Macro 來啟動/關閉錄音

以系統有安裝 FreePBX 為例
編輯 /etc/asterisk/extensions_custom.conf

...
...
; Recording a call manually while on the call
[macro-switch-callmonitor]
exten => s,1,set(rfile=${STRFTIME(${EPOCH},,%Y%m%d-%H%M%S)}-${CALLERID(num))
exten => s,n,Set(record=$["${record}"=""|"${record}"="0"]) ; toggle the record flag
exten => s,n,Gotoif(${record}?101)
exten => s,n,StopMixMonitor()
exten => s,101,MixMonitor(${rfile}.wav,,) 

編輯 /etc/asterisk/features_applicationmap_custom.conf

callmonitor => *1,caller,Macro,switch-callmonitor
或者
callmonitor => *1,self/both,Macro,switch-callmonitor 

編輯 /etc/asterisk/globals_custom.conf

DYNAMIC_FEATURES=callmonitor

TIPs：

修改 globals_custom 可以讓內外線都能啟用這功能。

要限制外線或內線，才能啟用此功能時，必須在 outbound 或 inbound 的 context 內加上
Set(DYNAMIC_FEATURES=callmonitor)

補強一：從資料庫 CDR 取出 from & to 作為錄音檔的命名規則

macro-myautomon：

[macro-myautomon]
exten => s,1,Set(DYNAMIC_FEATURES=myautomon)
exten => s,n,Set(MONITOR_FILENAME=${STRFTIME(${EPOCH},,%Y%m%d-%H%M%S)}-${CALLERID(num))
exten => s,n,Wait(1)
exten => s,n,MixMonitor(${MONITOR_FILENAME}.wav,b,mv  /var/spool/asterisk/monitor/^{MONITOR_FILENAME}.wav /var/spool/asterisk/monitor/`/usr/bin/mysql -u root -p<db_pass> -N -B -D <db_name> -e "SELECT calldate,'From:',src,'To:',dst,'' FROM cdr WHERE uniqueid = ^{UNIQUEID}"|sed -s s'/\s/_/ g'`.wav

錄音檔輸出格式為：

-rw------- 1 asterisk asterisk  161644 May 17 17:54 2012-05-17_17:53:57_From:_101_To:_011800677522_.wav
-rw------- 1 asterisk asterisk  118764 May 17 17:51 2012-05-17_17:51:16_From:_101_To:_011800677522_.wav
