try to add an alias statement containing the domain your server is responsible for....i recall it gave some trouble if I don't put it and only set TLS...
alias=10.202.200.132
Hope it solves it, samuel.
2006/7/25, Stephen Paterson Stephen.Paterson@aculab.com:
Well, the failed parsing is something of a red herring - it has exposed a bug in my ACK which only manifests on receipt of a non-200 response.
I've worked out how to enable lots more logging and looking at it, openser seems to run through several iterations of something or other and by the time it's finished the INVITE contains 6 Record-Route headers (all identical), 7 Via headers (all identical but the original) and 6 identical P-hint headers. It then is over 2048 bytes and the 513 is sent. Does anyone know why it's complaining about big messages for transports other than UDP?
When I remove the message too big check from the config I start getting a 483 - too many hops. Looking at the logs it shows openser stuck in a loop adding Via, Record-Route & P-hint headers. All the while it is decrementing Max-Forwards so it does eventually break out of this loop.
It looks like openser is forwarding the INVITE to itself. This should terminate with loop detected after one iteration but it carries on for 70 until Max-Forwards = 0. I can't work out why it would be doing this.
Any thoughts?
Cheers
Steve
P.S. Cesc. To put your mind at rest, the contact header is configurable to have a user part. I'm just lazy :)

No problem in terminating to yourself ... but i mentioned the loop not just because that. In the log you sent, you mention ...

so ... if the same message at the beggining of your main route is repeated 10 times, it means that you get 10 times the same message ... or you pasted the same xlog 10 times along your config file?
I would add this also at the beginning ... xlog("received message [[$mb]]\n\n");
print the received message ... you may discover the "loop" ...
Cesc PS - your application sends a contact without user part ... you may want to improve that ... On 7/25/06, Stephen Paterson Stephen.Paterson@aculab.com wrote:
It's not really a loop in the sense of 'loop detected' - both ends of
the 'loop' terminate the messaging. So I register my UA with the proxy ( steve@blah) and call steve@blah from the same UA - just makes it easier to test while in development. You need a UA that can handle multiple calls of course. That isn't the problem though. If openser thinks this is a loop detected it is wrong. A loop detection is where a request has been routed back to a proxy that previously forwarded the request thereby creating a situation where the request will be forwarded indefinitely. There is nothing wrong with terminating a call on the same equipment that originated the call.

You have a loop ... don't you? From and To are the same ... ok ... contact isn't (but it is missing the user part) ... but the request uri is yourself again ... what are the IPs of the UAs and Proxies involved? You mention that u had your "own" application? i think you are doing something wrong there ... which triggers some error in openser ...

This look to me like the URI is correct on receipt but is somehow lost
during the parsing.
Would the developer's forum be a more appropriate place for this? It
looks like a bug. I've also had a suggestion from Cesc that openser is possibly not yet that stable when it comes to the sips scheme (I guess it was implemented using transport=tls).
Cheers

Hi Daniel,
If I add this line (xlog("received request uri is [$ru]\n");) to the
beginning of route (shown below) openser won't start complaining about a bad config file, is there a typo maybe? A shame as it would be nice to see that in the log - I'm finding it difficult to be confident that what we are sending is correct as it is encrypted! I didn't notice before but I am also receiving a 513 as the final response but the check in the following bit of code is before loose_route (the message is also only a little over 1KB).
Is this the config snippet you meant?
route{ # log("received request uri is [$ru]\n"); -- openser will not
start with this line uncommented
it must be xlog("...") instead of log("...").
And you must load xlog module to have the function available in
script.
You can print the incoming message to the syslog via:
xlog("received message [[$mb]]\n\n");
Watch the logs to see what you receive from the net.
Cheers, Daniel

I guess you mean in the config file but just in case, I have not
altered the source so it should be exactly as is in openser-1.1.0-tls.src.tar.gz.

Seeing the error messages stack I see that the error occurs first
during
the loose_route() processing. Did some other method changed the
r-uri
before? Maybe the config file will help to see what could be wrong -
the
snippet from main route till loose_route() should do it.
To be sure that the r-uri as it comes from upstream is valid or not,
add
the following at the beginning of the main route block:
xlog("received request uri is [$ru]\n");
The xlog function parses the r-uri to be sure it is valid.
Cheers, Daniel

Hi all,
I've just started using OpenSER to test our SIP implementation and have encountered a problem with TLS early on. I can register with
the
server without any problem but my calls fail. The logging from the server shows:

This would suggest that my (for example) From header contains a
URI
of: sip:! Not overly useful you might say. Now, the same INVITE without encryption works fine with OpenSER (using either TCP or
UDP)
and a serialisation of the INVITE immediately before encryption (shown below) shows the correct URIs in all the right places.

For the moment I am pretty much assuming that this is a problem
with
our implementation as it is still under development but I can't
work
out what. 2 questions:
- Does anyone have any general thoughts as to what might be going
wrong? 2. Is it possible to get more logging from OpenSER that might shed some light?
