The issue of the negative timestamps may be fixed, but there is still 
something serious broken with IAX2 timestamp generation since the new time 
manipulation function patch went in.

Check this log of an outgoing IAX2 call.  CVS-HEAD 05-07-20.

This totally breaks the jitter buffer on the receiving system.  
Conversely, doesn't have an audible effect if you aren't using the buffer.

This is bug number 4747.
