Daniel,thank you for the suggestion, I followed the tutorial and got it up and running, however I am still experiencing the same issue, dropped calls after 30 seconds. Furthermore the output of tshark -i eth0 -R sip does not show any errors such as too many hops, everything looks very clean but I still cant get more than 30 seconds out.I have a default config with mysql enabled and nat. rtproxy is running as well.Any help is greatly appreciated.On Mon, Apr 16, 2012 at 1:31 PM, Daniel-Constantin Mierla <miconda@gmail.com> wrote:
Hello,
ngrep trace (I haven't seen any yet in the thread) of such call can help seeing if Record-/Route and Contact headers are properly set and maintained during the call. It might be a broken RR handling in a device or a wrong update of contact address.
On the other hand, in the config, I saw presence being loaded -- if you need that, then start with kamailio 3.2.x, here is a tutorial:
http://www.kamailio.org/wiki/install/3.2.x/git
It comes with a default config file where is very easy to enable nat traversal as well as presence handling -- just read the top of config file and add the appropriate #!define directives.
1.3.x is anyhow way too old...
Cheers,
Daniel

By the way - you can add:modparam("htable", "htable", "forw=>size=8;autoexpire=7200;")modparam("htable", "htable", "mustforw=>size=8;autoexpire=7200;")

Thank you Stoyan
I added the routing config as you suggested but it still drops the call after 30 seconds.
Any other suggestions?
Note: my nathelper module is commented out because I can't get it to work, here is my mod list:

Some time ago, I had similar problem.
This was my solution:if(is_method("INVITE")){ds_select_dst("1","4");$sht(forw=>$ft)=$du;sl_send_reply("100","Trying");route(RELAY);exit();}
if ( is_method("ACK|BYE") ) {if ( t_check_trans() ) {t_relay();exit;} else {if(($sht(forw=>$ft))=~$td){
$du=$sht(forw=>$ft);}else if((($td=="sip.mydomain.com")||($td=="ip.of.my.domain"))&&($si=="ip.of.my.domain")){$du=$sht(forw=>$ft);}t_relay();exit;
I am new to opensips so I am not too familiar with the routing logics, a google search on that error suggests that there is a problem with the route config where its creating a loop exhausting the Max Hops. The way I configured my clients uses my server as a proxy.
Any help is greatly appreciated!

38 seconds sounds pretty close to 30 seconds. Could those 38 seconds be a 30 seconds after the actual answer packet?
If so, you might want to look at ACK and OK packets not arriving correctly because of NAT, wrong IP selection in openser , etc...
A simple tshark might help you out to debug from a higher perspective : tshark -i eth0 -R sip
good luck!
