  Hi,


  do noop(${AMDCAUSE}) after  exten => 1,1,AMD() , run some test calls and find out why the call was detected as Answering Machine and adjust amd.conf accordingly. if I recall correctly, you can also see the AMD flow in Asterisk in verbose mode.


  I'd suspect low silence_threshold . I usually set it 384, but it's very dependent on carrier.

    Hi,
    I have IVR and when I press 1, asterisk calls my mobile phone.
    If my mobile phone is offline, asterisk transfers to asterisk voicemail.
    I'd like asterisk detects my mobile voicemail and if my mobile voicemail answers, asterisk transfers to asterisk voicemail.
    For that, I used AMD.
    So I have problems ! Asterisk detects answering machine everytime!
    How do I do please ?
