We are migrating an application from a platform that had enhanced call analysis builtin(Voice and Answering Machine Detection). We used the Voice Detection to determine when play information to the callee about the inbound caller. Waiting an arbitrary amount of time after the call is answered solves the problem in most cases, but we had complaints that the information was played too fast or not fast enough after the call was answered. Waiting for Voice Activity seems to satisfy those complaints. - Duane From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Michael Collins Sent: Thursday, July 14, 2011 7:34 PM To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] VAD Detection on Outbound Call So you don't want to start the prompt at 500ms after you hear the answer, but instead, until you hear some voice activity? Just curious - what problem does that solve? -MC On Thu, Jul 14, 2011 at 3:29 PM, Duane Gilbert <Duane.Gilbert@patlive.com> wrote: Is there a way either using the Dialplan or Lua script to detect when Voice Activity(VAD) is present on an outbound call? I am using the group_confirm_key/group_confirm_file variables to prompt the user after the outbound call is answered, but it would be nice to not start the prompt until after Voice Activity is detected on the line. - Duane _______________________________________________ Join us at ClueCon 2011, Aug 9-11, Chicago http://www.cluecon.com 877-7-4ACLUE FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org
