Hello,
I am seeing the following message repeatedly in my log file. I am
guessing I have a server or servers misbehaving. Where might I be
able to check for this error condition and log appropriately? I have
attached my current configuration file for reference.
Thanks!

Perhaps I should clarify what I am looking for a bit. I am guessing
based on the log "no via found in reply" that I would need to check
for this condition in my onreply_route[1] block.
Based on my knowledge of SIP, all reply responses are REQUIRED to have
a VIA header to ensure the response traverses the same path as the
request... correct?
Would the following effectively deal with this condition, or would
sending a 500 error in response to a reply cause problems down stream?
onreply_route[1]{
if(!is_present_hf("Via")){
sl_reply_error("500","No Via found in response.");
}
}
Thanks for anyone's assistance.

Tried adding that log into my onreply_route[1] block, but it didn't
work. I can't seem to figure out I can possibly capture the SIP
message which is generating this error. Any help would be much
appreciated.

How often do you get this error?
IIRC, last time when I got this type of error it was related to a
missing Via header into a SIP reply.
Can you capture/sniff the traffic and check if all the received
replies are sane (via header is present)?
Another idea would be to capture the bogus message into the error_route:
http://www.kamailio.net/dokuwiki/doku.php/core-cookbook:1.5.x#error_route
and then print the message via $mb:
http://www.kamailio.net/dokuwiki/doku.php/pseudovariables:1.5.x#sip_message…
I haven't checked the code to see if this type of error will end up in
the error_route, but is it worth a try.
If it's not caught, please open a bug, because it should be.

Ovidiu Sas

Ovidiu,
Thank you for your pointer. I could capture all the SIP traffic, but
it would be a LOT of data to sift through. This machine processes
hundreds of thousands of calls per day. I have tried the error_route
handler to see if it shows up there... fingers crossed. I was unaware
of that handler before now.
Thanks for the info!

Hello Geoffrey,
With tcpdump, you can capture data in buffers and rotate the buffers
and keep only the latest 2-3 buffers (check the man page).
As soon as the error arise, you stop the traffic and your bogus
message should be in your last buffer.
Just an idea ...
Also, if your cps is not very high, you can print the callid of each
request/reply, and when the error arise, you can correlate it with the
callid.
Regards,
Ovidiu Sas

Ovidiu,
Thanks for your continued input. I currently have the error_route
block configured with some logging. I am hoping this will be
sufficient to capture the condition. The error hasn't happened today,
traffic has been very light as it is Eastern and Passover, and I
suppose people have better things to do than be on the phone :)
If I get the log message and nothing from error_route, I will
definitely do a tcpdump of the SIP port and try to correlate the
timing.
thanks!
Geoff

Hello Geoffrey,
With tcpdump, you can capture data in buffers and rotate the buffers
and keep only the latest 2-3 buffers (check the man page).
As soon as the error arise, you stop the traffic and your bogus
message should be in your last buffer.
Just an idea ...
Also, if your cps is not very high, you can print the callid of each
request/reply, and when the error arise, you can correlate it with the
callid.
Regards,
Ovidiu Sas

Ovidiu,
Thank you for your pointer. I could capture all the SIP traffic, but
it would be a LOT of data to sift through. This machine processes
hundreds of thousands of calls per day. I have tried the error_route
handler to see if it shows up there... fingers crossed. I was unaware
of that handler before now.
Thanks for the info!

How often do you get this error?
IIRC, last time when I got this type of error it was related to a
missing Via header into a SIP reply.
Can you capture/sniff the traffic and check if all the received
replies are sane (via header is present)?
Another idea would be to capture the bogus message into the error_route:
http://www.kamailio.net/dokuwiki/doku.php/core-cookbook:1.5.x#error_route
and then print the message via $mb:
http://www.kamailio.net/dokuwiki/doku.php/pseudovariables:1.5.x#sip_message…
I haven't checked the code to see if this type of error will end up in
the error_route, but is it worth a try.
If it's not caught, please open a bug, because it should be.
Regards,
Ovidiu Sas

Tried adding that log into my onreply_route[1]
block, but it didn't
work. I can't seem to figure out I can possibly capture the SIP
message which is generating this error. Any help would be much
appreciated.
