Could someone enlighten me as to what could cause this error?

Housekeeping asks: Is the problem still there in recent CVS?

I've been trying to get a hold of Duane and he did call me back, but then I left for LA before I could call back.  I don't think any recent changes will have affected this issue, and I will have to call him back when I get back to HSV.

This warning appeared when ast_rtp_offered_from_local was introduced into the code (rtp.c 1.84 -> 1.85).

I hope debug output below will help you to identify the problem:
