Author: mikej Date: Tue Dec 16 16:20:22 2008 New Revision: 10829 Log: Fri Nov 21 04:52:55 CST 2008 Pekka Pessi <first.last@nokia.com> * nua: try to cope if a re-INVITE nor its ACK contain SDP Some SIP user-agents use INVITE without SDP offer to refresh session. By default, NUA sends an offer in 200 OK to such an INVITE and expects an answer back in ACK. Now nua tries to recover from such a Offer/Answer protocol error. Also, if NUTAG_REFRESH_WITHOUT_SDP(1) tag is used, and if the re-INVITE was received without SDP, no SDP offer is sent in 200 OK. Thanks for Anthony Minessale for reporting the problem.
