Current problem:

Working with Sofia-SIP.

I've previously had problems because my app is running on the same machine doing the NATing, which caused great confusion with port mapping. I'm not sure how I solved that, or if the current problem is related or not.

The problem is that my app (UA) doesn't get a "callstate ready" when answering a call. I do get a callstate completed.

Could be SDP-related.

I think this app worked when I last worked on it, in August 2007.

Will continue tracking this down next time I have time.
