probably if the UA's are on the same network, when you send the package the package is going with the external ip on the SDP , when the call is stablished probably you router is not allowing to open the second lag because the UA's are trying to stablish from inside using the outside ip addressl, so when you go through rtpproxy this not happen both sides use the opensips (rtpproxy) ip address to sdp.
If my logic is not correct please somebody let me know. 2013/10/4 Rodrigo Ferreira <[email protected]> > Forcing the traffic through RTPPROXY worked, but why isnt working the > nat_uac_test? > > Kinda weird > > > > Atenciosamente. > Eng.° Rodrigo Ferreira > ITIL v3 Certified > > <http://br.linkedin.com/pub/rodrigo-ferreira/31/757/901> > > > 2013/10/4 Mike Tesliuk <[email protected]> > >> well, probably you softphone/ip phone, is using some kind of stun or >> other kind of nat features, so, nothing come to be detected, this can >> happen, so, if you will be ever using nat, you can force the rtpproxy >> without nat detection, this will solve your problem, if you read the >> documentation ( >> http://www.opensips.org/html/docs/modules/1.9.x/nathelper.html#id292854) you >> can see that this test are made over rfc1918 or different ip address >> from via and signalling >> >> The problem is probably the fact that when the call is stablished, the >> media cannot traverse, you have the correct ip information on sdp but the >> router does not permit the session to be opened, so, do a test forcing the >> use of rtpproxy without the nat detection, just force all trafic throught >> rtpproxy >> >> >> 2013/10/4 Rodrigo Ferreira <[email protected]> >> >>> I did that Mike .. >>> >>> my "nat_uac_client" isnt passing in any verification ... >>> >>> I did this .. >>> >>> if ( nat_uac_test("1") ) xlog("UAC TEST = 1"); >>> >>> if ( nat_uac_test("2") ) xlog("UAC TEST = 2"); >>> >>> if ( nat_uac_test("4") ) xlog("UAC TEST = 4"); >>> >>> if ( nat_uac_test("8") ) xlog("UAC TEST = 8"); >>> >>> if ( nat_uac_test("16") ) xlog("UAC TEST = 16"); >>> >>> if ( nat_uac_test("32") ) xlog("UAC TEST = 32"); >>> >>> if ( nat_uac_test("64") ) xlog("UAC TEST = 64"); >>> >>> in the beginning of the script, to see what is happening to my NAT, and >>> i got nothing. >>> >>> >>> >>> Atenciosamente. >>> Eng.° Rodrigo Ferreira >>> ITIL v3 Certified >>> >>> <http://br.linkedin.com/pub/rodrigo-ferreira/31/757/901> >>> >>> >>> 2013/10/4 Mike Tesliuk <[email protected]> >>> >>>> That howto is just a sample (with a lot of comments) to better >>>> understand of nat configuration (over my understand offcourse), so, you can >>>> check and compare with your configuration to identify about something >>>> missing >>>> >>>> >>>> >>>> >>>> 2013/10/4 Rodrigo Ferreira <[email protected]> >>>> >>>>> Yes I did Mike, >>>>> >>>>> and my SIP messages are ok. >>>>> >>>>> I will take a look at your tutorial. >>>>> >>>>> tks >>>>> >>>>> >>>>> >>>>> Atenciosamente. >>>>> Eng.° Rodrigo Ferreira >>>>> ITIL v3 Certified >>>>> >>>>> <http://br.linkedin.com/pub/rodrigo-ferreira/31/757/901> >>>>> >>>>> >>>>> 2013/10/3 Mike Tesliuk <[email protected]> >>>>> >>>>>> Did you try to made some debug rodrigo ?
