hi, I was wondering if in clients in a nat environment need to be in the dmz or need to have ports forwarded for kamailio to be used to connect the clients? I have setup kamailio with the nat settings but am still only getting one way audio. chances are it has not been setup correctly but just checking. If i try to connect the two clients from the same network i can get zrtp and 2 way communication working correctly. if one of the clients is on a different network the call initiates and answers but zrtp and 2way audio does not work. kamailio 3.3 running on ec2 ttyl,Dave
Hello,
what are you using for rtp relay? Sending here the sip trace of such call (e.g., ngrep) would help to spot if the signaling is updated correctly for nat traversal.
Cheers, Daniel

Hello,
what are you using for rtp relay? Sending here the sip trace of such call (e.g., ngrep) would help to spot if the signaling is updated correctly for nat traversal.
Cheers,
Daniel

hi,
I was wondering if in clients in a nat environment need to be in the dmz or need to have ports forwarded for kamailio to be used to connect the clients? I have setup kamailio with the nat settings but am still only getting one way audio. chances are it has not been setup correctly but just checking.
If i try to connect the two clients from the same network i can get zrtp and 2 way communication working correctly. if one of the clients is on a different network the call initiates and answers but zrtp and 2way audio does not work.
kamailio 3.3 running on ec2

Hello,
the sdp does not show that rtpproxy was engaged. Check your config, you can use debugger module with cfgtrace on to see what actions are executed.
Also, probably you have to advertise the public ip address of your ec2 instance -- see second parameter for rtpproxy module functions.

Hi Daniel, I do have the second param set to the public ip of the ec2 instance. Thanks for that. :) I also tried the debugger but that didn't show me anything specific but there were some errors in the output. I'm a little green on this subject so it might be out of my reach to put this together. I did see some notes about the zrtp hash so at least I know that the endpionts are trying to negotiate. And I know that it is a one way audio thing so it is probably nat related. Am going to do some more reading over the next few days to see if I missed something in the config. I used this document to configure the nat traversal:http://nil.uniza.sk/sip/nat-fw/configuring-nat-traversal-using-kamailio-31-a... Is it still relevant with version 3.3? thanks for your help!! ttyl,Dave Date: Tue, 11 Sep 2012 08:24:33 +0200 From: miconda@gmail.com To: jdavidthomson@hotmail.com CC: sr-users@lists.sip-router.org Subject: Re: [SR-Users] using kamailio with clients in a nat environment
