Thanks for helping out Hugh (and obviously Daniel)

I have made some progress by adding the modparam ("msilo", "outbound_proxy", "sip:my.domain.com:5061;transport=tls").
Now indeed the stored message gets delivered when a UAC registers.

But I just noticed that it was also filling up msilo db with "user xxx is offline!" messages, instead of sending that msg to the initial UAC sending the msg.
This likely means I'm doing something wrong with the routing, as it feels like it's in an endless loop. I think Daniel earlier suggested adding if(src_ip != myself) t_on_failure("FAIL_MESSAGE") to another poster that was having trouble with the exact same routing config, but I'm not sure exactly where to insert it.

Can someone experienced with the routing syntax point out my - likely obvious - mistake?

Cheers,
Peter

Hi,

We did have a working msilo implementation a while back, but we don’t use it any more, so I can only look back at the config files (which are a lot more complicated than yours).

 

We added the a modparam modparam("msilo", "outbound_proxy", "sip:MY_REAL_IP:MY_SIP_PORT;transport=tcp")

which will make it arrive on the local machine on the given socket (instead of localhost) to be processed, but that probably isn’t your problem.

 

Is it possible that Kamailio is trying to establish a new connection, instead of reusing the existing connection to the client? That would be visible as TCP SYNs in a trace and would cause a 408 after the timeout. We are using a separate outbound enabled edge proxy so this isn’t a problem for us.

 

Regards,

Hugh

I guess no one really knows why it isn't working either.

The only option I have left seems to be to try and update to the 4.2 nightly and hope that whatever's wrong is a bug with 4.1.4 and not a simple mistake in my routing syntax or logic.

 

Daniel, is 4.2 nightly debian package stable enough for a production system? Would you recommend I upgrade?

 

Thanks

Can anyone help please? I was supposed to have this server up and running hours ago and I can't think of anything to do next to help debug this.

 

Thanks

I removed the localhost listeners on TCP and UDP, and, as I suspected, Kamailio doesn't seem to like that.

Why isn't kamailio sending the message back through the TLS socket?

And here's the full routing block. I copied it from someone else on the list that was troubleshooting msilo a while back.

Also, I can confirm the message never gets delivered because it remains in msilo DB and kamailio logs shows it trying and trying.

Thanks for your help Daniel.

 

OK I ngrepped port 5060 and indeed the message tries to get delivered. However it never arrives at the client (1010 in this case).

I have added localhost listeners for UDP and TCP, even though all clients register through TLS only (could this be the root of the problem?). I added localhost listeners because I was getting the no socket found error message.

Hello,

can you watch the sip traffic on the network to see if the sip messages is sent out? You can use ngrep, like:

ngrep -d any -qt -W byline "sip" port 5060

Cheers,
Daniel

Hi,

 

This is most likely a stupid mistake on my route config, but msilo correctly stores messages for offline users, but when they come back online, the message never arrives.

 

Looking through the debug logs indeed there is an error, with status 408, which suggests kamaiio can't find a route to the user that just logged. Before I spend hours looking through all the routing blocks, perhaps someone more exprienced in kamailio can see the problem right away and offer a solution?

 

Thanks
