DISA的用法

wxgchinaunix

谁能解释下DISA怎么个用法,
我装的是trixbox1.2.3
买了一个x100p卡,电话打进来进入ivr,输入7,进入DISA,
下面是呼叫过程,
    -- Executing BackGround("Zap/1-1", "custom/HuanYing" in new stack
    -- Playing 'custom/HuanYing' (language 'en')
  == CDR updated on Zap/1-1
    -- Executing Goto("Zap/1-1", "disa|1|1" in new stack
    -- Goto (disa,1,1)
    -- Executing Set("Zap/1-1", "TIMEOUT(digit)=5" in new stack
    -- Digit timeout set to 5
    -- Executing Set("Zap/1-1", "TIMEOUT(response)=10" in new stack
    -- Response timeout set to 10
    -- Executing Playback("Zap/1-1", "enter-password" in new stack
    -- Playing 'enter-password' (language 'en')
    -- Executing DISA("Zap/1-1", "/etc/asterisk/disa-1.conf|from-internal" in new stack
  == Spawn extension (disa, 1, 4) exited non-zero on 'Zap/1-1'
    -- Hungup 'Zap/1-1'

提示输入密码后进入-- Executing DISA("Zap/1-1", "/etc/asterisk/disa-1.conf|from-internal" in new stack就没反映了,等着就是Hungup了,不知DISA是怎么用的,
