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! Geoff

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.

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. Geoff

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! Geoff
