freeswitch配置既能打電話又能語音識別問題（並個unimrcp傳自定義參數）

雙腿識別，通過訂閱事件獲取識別結果
為了能實現雙腿識別，這里通過Lua腳本使用freeswitch.Session來實現，call.lue放在freeswitch的script目錄下

-- call.lua

session:answer();

local caller_number = argv[1];     --主叫號碼
local called_number = argv[2];     --被叫號碼

local dest = "{ignore_early_media=false,bridge_early_media=true,origination_caller_id_number=caller,origination_caller_id_name=8888,call_timeout=120}user/"..called_number.."";
session2 = freeswitch.Session(dest);
-- hello為語法文件名稱
session:execute("detect_speech", "unimrcp {sid=5657}hello default")
session2:execute("detect_speech", "unimrcp {sid=5657}hello default")
freeswitch.bridge(session, session2);

 

注：其中{sid=*}表示要傳給mrcp的參數，即GENERIC_HEADER_VENDOR_SPECIFIC_PARAMS  參考地址：unimrcp-recognize-headers

配置撥號計划
