[asterisk-users] setting up AMD

[Michael Collins]

Hmm... not too sure what's up with this one.  I've only used AMD with
Zap channels, so I don't know if there are any hidden gotchas with using
SIP.

 

Has anyone else used app_amd with SIP calls?

now I have amd.conf set to this:
initial_silence = 3700
greeting = 2500
after_greeting_silence = 1200
total_analysis_time = 6000
min_word_length = 100
between_words_silence = 50
maximum_number_of_words = 4 
silence_threshold = 860


The resulting log is this:

I'm trying get this working.  I've looked through the list, and can't
see how to get AMD to print out more.  I have it call and say Hello like
I normally would.  I've tried to say more and less doesn't seem to
matter.  After I hangup it does recognize hangup.  Here's logging during
an attempt where I make outbound call and answer, but then hangup after
1-2 seconds:

The amd.conf:
[amd]
initial_silence            = 3500
greeting                   = 1500 
after_greeting_silence     = 300
total_analysis_time        = 5000
min_word_length            = 120
between_words_silence      = 50
maximum_number_of_words    = 5
silence_threshold          = 256

In extensions.conf
[outboundmsg1]
exten => s,1,NoCDR
exten => s,n,AMD
exten => s,n,GotoIf($[${AMDSTATUS}=AMD_PERSON]?humn:mach)
exten => s,n(mach),WaitForSilence(2500)
exten => s,n,Playback(outboundmsgs/msg1) 
exten => s,n,Hangup
exten => s,n(humn),WaitForSilence(500)
exten => s,n,Playback(outboundmsgs/msg1)
exten => s,n,Hangup

Peter,

It looks like your initial silence setting might be having trouble.  The
amd.conf file has a value of 3500 but the log file is showing 8000.  Try
changing the amd.conf to something like 3000 and issue a "reload" at the
CLI. Make another test call and see if the trace still shows 8000 for
the initial silence.  I think having an initial silence value that is
longer than the total analysis time might be causing the undesired
behavior.

 

Let us know what happens when you try to modify the initial silence
value.
