[Kamailio-Users] ERROR:core:receive_msg: no via found in reply

[Geoffrey Mina]

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.
