Playing around with WSS support:       if (nat_uac_test(64)) {           force_rport();       ......         if (!add_contact_alias()) {             xinfo("Error aliasing contact <$ct>\n");             sl_send_reply("400", "Bad Request");             exit;            } set_contact_alias() throws this error on ACK without Contact, add_contact_alias() doesn't (and thats OK). Is this the expected behavior? __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions * sr-users(a)lists.kamailio.org Important: keep the mailing list in the recipients, do not reply only to the sender!
