[asterisk-users] Answer Machine Detection

[Matheus Rossato]

Hi all,

    i'm trying to make AMD, Answer Machine Detection, to work on my 
outbound context but i can't get it to work, just on inbound context 
like whe i use the application Answer before AMD, but i need to make AMD 
to do the detection on an outbound predictive dialer integration. Follow 
are the inbound and outbound examples. My current environment is 
Asterisk 1.4beta3 and a Digum TE105P with ISDN E1. Have any one managed 
to do answer machine detection already?

[outbound]
exten => _x.,1,AMD
exten => _x.,2,Dial(SIP/${EXTEN}@10.1.1.203,,tT)
exten => _x.,3,Wait(2)
exten => _x.,4,Set(RECORDEDFILE=${CALLERID(num)}.wav)
exten => _x.,5,Record(${RECORDEDFILE},,,skip)
exten => _x.,6,Hangup

[inbound]

exten => _x.,1,Answer
exten => _x.,2,AMD
exten => _x.,3,Wait(2)
exten => _x.,4,Set(RECORDEDFILE=${CALLERID(num)}.wav)
exten => _x.,5,Record(${RECORDEDFILE},,,skip)
exten => _x.,6,Hangup
