Subject: [Asterisk-Dev] Re: Answering Machine detection<br>
<br>
Hi,<br>
Thanks to Matt and Steve for replying to my post :-) . Steve, I would <br>
really<br>
like to know more about your code like how it exactly works and how<br>
resource<br>
(cpu and memory) intensive it is.<br>
<br>
Matt, following are the details you asked for:<br>
I want my system to detect atleast 80% of the answering machines and <br>
that<br>
too within 1-3 seconds, just like dialogic boards.<br>
Otherwise there won't be much reason to replace the existing predictive<br>
dialer system with Asterisk.<br>
We're going to have 24 to 48 lines initially and it'll definitely be T1. <br>
We've not yet finalised which cards (Digium, Sangoma or if possible<br>
Dialogic) to use.<br>
Also, we'll be writing our own Predictive dialer application which will<br>
talk<br>
to Asterisk using its Manger API interface. <br>
<br>
I would be really grateful if you could guide me on the above and also<br>
throw<br>
some light on the following:<br>
- Does Asterisk support the Dialogic D/480JCT-2T1 board (That's what our<br>
current system is using) ? <br>
- Which is the best T1 card for use with Asterisk?<br>
<br>
