Thank You Reda,

Here is the entire trace of the 30 second call with ngrep, please let me know if this helps:

Hi,

This is what I wrote on another thread for the same problem.

---------
Well, 30 seconds seems to be the timeout of your SIP client: I suspect your client sends a 200OK but doesn't receive the ACK for it, and hence times out 30 seconds after and terminates the call. You can run ngrep to trace the call and see where the ACK is routed, and if it is routed to the correct address, if anything is not correct in its header. Personally, I run wireshark over an X11 tunnel for the GUI which helps a lot. If you provide ngrep trace, we may help you better.

I had the exact same problem once, but don't remember what the reason was.. maybe incorrect loose routing section or incorrect record-route or incorrect address in contact header of 200OK..

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.

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

I am using nathelper and rtpproxy.
We had no serious problems with those modules.
My idea was to overwrite wrong addresses in ACK and BYE packages, because they kept reentering kamailo, instead of being forwarded where they have to go.

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;

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!

Greetings list,

I am experiencing a strange behavior with openser 1.3.2 running on ubuntu 10. I have a basic configuration (see bellow) and i am using Linphone for iPad as my client. I have 2 users registered and I am able to place calls no problem. The problem is that the calls (audio or A/V) drop after 38 seconds exactly, this behavior is pretty consistent, 38 seconds is all I can get. There is no firewall in front of the clients.

Here is my configuration, ip addresses changed to protect the innocent:


You can see the logs of the call here (the majority):


Am I missing something or is there anything that needs to be changed in the routing/configuration to achieve basic functionality?

Thank you in advance!
