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?
