Hi Klaus, This is a nat trick. Based on the received/rport params of the answer to this OPTIONS, linphone gets a chance to put a correct contact address in the 200 Ok answer. Which will allow further requests to be received. Of course when the proxy is nat-aware (in this case, inserts a record-route, like sip.linphone.org) this is useless.
