[Asterisk-Users] dropped calls from queue

[Tony Buser]

We're having a strange problem with our receptionist.  She runs an xpro 
softphone and we're using a queue to handle incoming calls.  It seems 
nearly all of the calls that come in through the queue get dropped.  At 
first we thought it might have been human error (clicking the wrong 
button in xpro or something) or that the person waiting in the queue 
just gave up and hungup, however it seems to happen when the following 
gets logged:

Apr  7 14:53:35 WARNING[60424217]: File 10 does not exist in any format
Apr  7 14:53:35 WARNING[60424217]: Unable to open 10 (format G729A): No 
such file or directory
Apr  7 14:53:35 WARNING[60424217]: Agent on SIP/hrutter-c6fa hungup on 
the customer.  They're going to be pissed.

Anyone have any idea what could be causing this?  We do force using g729 
and to the best of my knowledge we have more then enough licenses when 
this happens.  We're running cvs as of around March 23rd, I guess I 
should update that?
