Thanks for the references to examples. I've been through them, gotten
rid of force_rtp_proxy() since it's considered depreciated - but still
get the same error:
/usr/local/sbin/kamailio[31035]: ERROR:nathelper:force_rtp_proxy:
incorrect port 0 in reply from rtp proxy
I do this in my main route
1. A force_rport() for everything
2. Check if it is likely NAT all with nat_uac_test("19"), and if true...
3. If it is anything but a REGISTER, fix_nated_contact()
4. If it is an INVITE, do rtpproxy_offer() - and an
unforce_rtp_proxy() if it is BYE
5. If there is no to tag, do add_rr_param(";nat=yet")
In the onreply_route[1] this is done:
A. xdbg("incoming reply\n") ...and I have no clue what this is for(!)
B. If it 183 or 200, rtpproxy_answer() is called
...and that is it, but still the "incorrect port 0 in reply from rtp proxy".
Any ideas?

I've been looking around for documentation to
understand rtp proxy
with Kamailio better, but with no luck (or I might be quite
thick-headed!).
Anyone know of example configurations with rtp proxy and Kamailio, so
I can start seeing what is wrong with my config (below)?
Thanks!

Sorry, I didn't understand that. Is it good
or bad that it is
asymmetrical? And if not, what should it be? As far as I understand
from my config, it first checks if NAT is set, and if so, it goes to
force_rtp_proxy if it's INVITE and unforce_rtp_proxy if it's a BYE. Is
that not correct?
