[OpenSIPS-Users] Typo in message header and how to catch it

[Răzvan Crainea]

Hi Cindy!

for TCP: the error seems to occur while reading the message. Are you 
sure the error route is not called for this type?
for UDP: Are you passing any flags to the sipmsg_validate() function? 
Have you tried using the 's' flag [1]?
