Hi,
 

I wondering if anyone has experienced this issue?

The first part of the prompt is missed, i.e. not played out, as if the application has started too quickly and before the audio channels have been correctly set up on the PSTN.
So instead of "Welcome to ACME coporation", the caller hears "... to ACME corporation" and does not hear some or all of the word "welcome".
This is a mico app. The VRU leg is played on the local PSTN Gateway (so no RTP Streaming from a distant device).
the issue is occuring on CVP 8.5 on SIP.

The issue does NOT occur for the same application on CVP 7 on H323.

The Gateway is configured with the below

 
ivr prompt streamed none

voice rtp send-receive
 

 
Anyone else have any good ideas to help reduce or elliminate the issue?

The problem is that there's no explicit synchronisation between the media being established and the point at which the VoiceXML plays the first prompt.  Suggest you add a short delay into bootstrap.tcl.  Add "param delay 1000" on the bootstrap service on the gateway.  1000 is the delay in ms.  Adjust at will and see if you get any improvement.   Reload the application after you've added/changed the param to make sure it's picked up -- "call appl voice load bootstrap" assuming that's what you've called it.

Paul, Janine, Bill,
I really appreciate the effort for responding.
Jaine your solution I had already thought of. It would be a pain, but it would work!
However Paul, your response was exactly what i was looking for. I never knew of this paratemter before.
Very very useful. Thank you so much.
