We have just completed development of our own version of AMD which is
much better. It plays back the audio while simultaneously doing the
analysis which removes the dead silence at the beginning of the call. However we use a combination of AMD and carrier detection for leaving messages on cell phone VMs. It's not perfect but will be a big improvement over your current method. I'll send you the details in a separate email shortly.<br><br><div>Alan<br>www.group2call.com<br></div><br><br>--- On <b>Tue, 6/24/08, Dave Batchelor <i><dave@greenroomcreations.com></i></b> wrote:<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;">From: Dave Batchelor <dave@greenroomcreations.com><br>Subject: [asterisk-biz] AMD Tweaking<br>To: "Commercial and Business-Oriented Asterisk Discussion" <asterisk-biz@lists.digium.com><br>Date: Tuesday, June 24, 2008, 10:49 AM<br><br><pre>Out of curiosity, has anyone made enhancements or modifications to the <br>AMD portion of their Asterisk setup? We currently run a service that <br>places calls for
businesses and are running into issues where when their <br>users answer the phone, they may have to wait 8, 10, 20 seconds before <br>the<br> message begins to play, also we're running into the problem where <br>the voicemail of some major cell carriers like alltell and sprint arent <br>being detected and are being handled as a live answer.<br><br>It obviously varies from phone to phone and we realize there's no way to <br>get it 100% for everyone. Perhaps the best way to handle it is to have <br>a rapid detect version and a more accurate detect version and give each <br>business the choice. We were wondering what the best settings for such <br>a setup would be. Currently, we run AMD with the following: <br>3500|1500|300|5000|120|50|5|256 followed by a waitforsilence with the <br>following: 2000|1.<br><br>While we know it isn't going to work perfectly we want to at least get <br>it working correctly so it leaves messages on all major cell phone
<br>providers. If there is a company who is very knowledgeable in AMD we'd <br>be very interested in paying you to help us create the best<br> possible <br>solution.<br><br>We are open to any suggestions or advice on this one as we've tried <br>tweaking the values and all that seems to accomplish is an improvement <br>on one phone and a backstep on another.
