<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;"><DIV>After the second attempt that Kamailio sends a call towards an ip address and gets a negative sip response say 503, kamailio will block that ip route for approx 4 minutes and sends 401 unauthorized immediately to the sip client. That ip route can be a gateway which is sending a negative reponse for certain destinations only and this may be due to a problem which is beyond the gateway itself; so I want to avoid blocking the complete route automatically.</DIV>
<DIV> </DIV>
<DIV>It appears that, in version 1.5 the route gets blocked for a longer period.</DIV>
<DIV> </DIV>
<DIV>Appreciate any help.</DIV>
<DIV> </DIV>
<DIV>Thanks,</DIV>
