[asterisk-biz] Better Answering Machine Detection Methods?

[Dave Batchelor]

We've been using the standard Answering Machine Detection for our 
outbound calling with mediocre success.  We seem to run into quite a few 
problems where people answering the phone and saying hello and the 
system being quite delayed before playing the greeting to them. 

Is anyone aware of a better more advanced way to do AMD.  I was 
wondering if it is possible to have it setup to do AMD multiple ways, 
for example:

Since people expect our calls, and recognize the caller ID, is it 
possible if we have the greeting play right away if nothing is said on 
the phone..
or
If someone picks up and says hello, to play shortly after..
or
Leave the message on the answering machine if it goes to one.

Any help would be greatly appreciated as we're trying to find a better 
way to do this.  We get alot of people complaining about nothing 
playing, but then again probably 50% don't say anything when the call 
comes in.

Thanks in advance,
Dave
