<p class="MsoNormal"><span style="color:#1F497D">This customer Jason is referring to has their audio files setup with no lead-in silence (0ms). I’ve seen vague references that 100-500ms is a good best practice. Does anyone have any definitive references or
experience as to what the Best Practice for lead in silence should be? <o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">BTW packet capture (and rtp playout with wireshark) on the CUBE proved the audio was being sent to the carrier but is being truncated in the Carrier Network.<o:p></o:p></span></p>

<p class="MsoNormal">Customer is running UCCE with a VXML gateway that has a CUBE in front of it.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The VXML prompts start to play before the CUBE sets up the audio, so once the audio comes in the end user has missed the first 1-2 words. Normally I tell the customer to start record the prompts with a 2 second delay before speaking.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any ideas why the CUBE/VXML audio isn’t cutting thru fast enough? Debug ccsip messages on cube/vxml. They are using Early Offer as well.<o:p></o:p></p>
