asterisk users - Sep 2009 - Voice Playback cutting first word or so of audio file

When I call inbound with a cell phone (via SIP PSTN trunk) some of my  
prompts the first word is cut off.  I'm assuming the prompt is needing  
to be transcoded on the fly and it's not getting transcoded fast  
enough.  I did a file convert to create gsm versions (currently they  
are referenced in my dial plan with no extension


Seem to have same problem.  How do I determine which file it's  
playing, for one and what is the likely cause of my issue?  Note: If I  
call from a landline, this problem doesn't exist.  I'm assuming there  
is some way to determine if resources are being expended to transcode.

You need to add a Wait(1) after the Answer()

I've always added a wait(1) as the first line in those plans with the 
problem and it goes away. I think it's that the prompt starts before 
the call is finished being set up.

Actually, it might fix it but I did that for a completely different 
reason having to do with caller ID on a PSTN line.
