We have two different approches to testing nat in the rtpproxy and mediaproxy configs that introduced the error. We are discussing how to resolve this before notifying people about this issue.
Try: 192. onreply_route[1] { 193. 194. if (isflagset(6) && status=~"(180)|(183)|2[0-9][0-9]") { 195. if (!search("^Content-Length:\ 0")) { 196. force_rtp_proxy(); 197. }; 198. } else if (nat_uac_test("1")) { 199. fix_nated_contact(); 200. }; 201. } fix_nated_contact() should go in between line 194 and 195.
