Description: 
Reopen of issue 10441

Since upgrading to 1.4.17 from 1.2 I get this with one of my clients 100%
of the time.  I have a RTP debug saved of a transaction.

Please email me for full log.

I had to send the RTP traffic to an 1.2 Asterisk box and then forward it on
from there.  Then I have no issues.  The client is running voipswitch.  

Currently it causes issues with voice quality.  The audio quality is very
poor.

When I route through 1.2 instead of 1.4 it cleans up and sounds fine. 
Also the cli error messages disappear.

I can do any traces you would like.  tcpdump etc.
