Hi Amanda, be sure the devices are symmetric from RTP point of view - otherwise the traversal will not work. Also note that first you need incoming RTP (from client to RTPproxy) in order to be able to send RTP behind the nat. regards, bogdan Amanda Mattiuz wrote:

Hello! I'm using rtpproxy to handle NAT, but right now I have problems of unreacheable host... I believe client's firewalls are blocking UDP traffic coming from the proxy ... I tried to change port range and nothing seem to make it work... I was wondering if any of you kows something that may fix it....

HI Use ethereal, or ngrep if not install Download it and install on the Clients side and server side ( for Ethereal) and Ngrep in Server, So that U can see the SDP section in ngrep and in Ethereal u can both rtp packets and SDP messages, I seen the urs Debugs of the OpenSER it doesn't show the properly.

Humm... Imay be using an old version of Ethereal, because it does not explicit show RTP or SDP packets. I will run tests and post the RTP/SDP capture, thanks a lot for the help! Just one thing, yesterday I run nmap to check the ports on both clients and in both of them I saw that ALL UDP PORTS are blocked/filtered by firewall/router/proxy.... do you think this may be the problem? I checked the client source code and I seems to be synmetric..... On 4/5/07, raviprakash sunkara <sunkara.raviprakash.feb14(a)gmail.com> wrote:

Hello all!! Here it goes my SDP capture....

Sorry, I forgot to post the SDP message from the client that originates the INVITE. Here it goes: Content-Type: application/sdp v=0 o=sip:amanda@195.176.182.183 0 0 IN IP4 84.72.112.122 c=IN IP4 127.0.0.1 <http://195.176.182.183/> t=0 0 m=audio 2100 RTP/AVP 0 a=PCMU/8000 I notice from here that the audio ports described here and in the server SDP message are different. Could this be an issue?? Amanda On 4/14/07, Amanda Mattiuz <amattiuz(a)gmail.com> wrote:

Just another question (for today at least.... ;-) ) : Does anybody have a client that works with RTPproxy and Openser that I can use?? Maybe the problem is in my client, I don't know.... so It would be nice if I could try with anotehr client that I know that works...

Hi Mattiuz , Please follow the step bu steps in SDP section when invites and 200 Ok Responsing from UAC and UAS ie.. in fixed_nated_sdp( flag) test one by one from 1 to 12 flag, Because of Some Fire will blocks the SDP messages of mail in Contact -header ... and other o and c and also m option in Sdp message body.
