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?
