There has been some development going on (and some maintenance)
relative to iax, rtp, jitterbuffer, etc. Maybe something did or didn't
get moved into stable impacting this.

My next step would be to implement cvs-head to see if that corrects
the problem. Don't know of any other way to ID the issue other then
that.
