Hi Bogdan, Thx for the reply and appreciate your help. I've turn on the debug to level 9. Below are the log:
Nov 20 10:19:31 OpenSIPS2 /usr/local/sbin/opensips[1912]: DBG: ==============START==============, si=y.y.y.y Nov 20 10:19:31 OpenSIPS2 /usr/local/sbin/opensips[1912]: DBG:core:parse_headers: flags=ffffffffffffffff Nov 20 10:19:31 OpenSIPS2 /usr/local/sbin/opensips[1912]: DBG:nathelper:check_content_type: type <application/sdp> found valid Nov 20 10:19:31 OpenSIPS2 /usr/local/sbin/opensips[1912]: DBG: ==============END==============, si=y.y.y.y I've printed out the $si variable before and after the fix_nated_sdp. Both IP are the same which depicts A party external IP. A -> Proxy -> B, is the INVITE packet flow from A party to B party in a P2P scenario. I've attach the screenshot of the diagram which I'm trying to explain in my previous email. I guess the plain text email screw all the text position. BTW, I'm still using Opensips 1.4.5 for our lab. ------------------------------------------------------------------- Regards, Lawrence Na Chong Guan ------------------------------------------------------------------- > From: Bogdan-Andrei Iancu <[email protected]> > Reply-To: OpenSIPS users mailling list <[email protected]> > Date: Thu, 19 Nov 2009 19:38:51 +0200 > To: OpenSIPS users mailling list <[email protected]> > Subject: Re: [OpenSIPS-Users] Fix_nated_sdp > > > Hi Lawrence, > > Are you sure you SIP request is not spiralling on the proxy: A - > Proxy > -> Proxy -> B ?? simply print the $si variable from script (via xlog) > just before the fix_nated_sdp(). > > Regards, > Bogdan > > Lawrence Na (my-...@vyke) wrote: >> Hi All, >> >> I¹ve got a problem with fix_nated_sdp, whenever I call the method in >> the request route it doesn¹t seems to take effect.
