<p class=MsoNormal>I am running into a situation where the nathelper module is
causing openser/kamailio to crash. The crash occurs when opensbc sends
and invite to openser with an extra CR in the message body. I already
contacted the opensbc folks about this. I just wanted you all to be aware
that this could cause serious service interruptions.<o:p></o:p></p>
