Hi Henning,

Yes, the gateway is totally off-line so no response comes back.  I do
have failure_route in the config.  This is related to another active
post from me "Carrierroute failover domain not working" so I'm sure
this is a redundant post, but your input is appreciated.

The pastebin has my kamailio.cfg, the kamailio debug trace and the
error received by sipp and the ngrep capture.
