Answering Machine detection is very CPU intensive in Asterisk and will
very much limit your capacity per server if you implement it. This is
because unlike expensive Dialogic boards, Digium cards do not have an
array of on-board DSPs to handle the signal processing needed to
accomplish good Answering Machine detection.<br>
<br>
What percentage of Answering Machine detection are you trying to achieve?<br>
<br>
How much delay time is acceptable to you? Dialogic systems range from
1-3 seconds of delay while they process the signal to determine whether
it thinks there is a person on the other end.<br>
<br>
How many Lines do you think you are going to be able to have dialing outbound with Answering Machine detection active?<br>
<br>
What kind of lines(trunks) will you be using this with? (T1/E1s, SIP, IAX...)<br>
<br>
What predictive dialing software are you planning on using on Asterisk?<br>

<div><font face="Arial" size="2">Can anyone help me Answering machine detection
using Asterisk. I have already tried the <strong>"Background"</strong>
application but I want something more reliable -- like the PAMD supported by
Dialogic boards. Is PAMD supported on Digium or Sangoma hardware? If yes , how
can it be used through Asterisk?</font></div>
<div><font face="Arial" size="2">We want to implement a Predictive Dialer based on
Asterisk PBX so its really important to have a very accurate Answering Machine
detection system.</font></div>
