I just realized that 3.1 executes main routing block when broken SIP message

OK, that can be fixed very easy. Iirc, in some cases you don't get the
sip message in the config if it is really broken, but I am not sure if
error_route was executed for that case anyhow.

Daniel, I think this could be implemented without re-introduction of
error_route,
it will not be re-introduced for sure, we have now a different core
framework which care reuse event_route mechanism.
In the past the error route was executed when the error was discovered,
so it several places of the code, and I am not sure that the core can
continue up to config execution of something is really broken.
I will have it in mind when I get some spare time.

what about core parameter route_on_error=yes/no (default no)? If
route on error is enabled, then sanity module will do the trick:
route{
if(!sanity_check("1159")) {
xlog("L_INFO","Bad message from $proto:$si:$sp\n$mb\n");
break;
}
....
It will be up to script writer what to do in main routing block if
message parsing fails.

It would be nice to get error_route back. The route was trivial in my
cfg file:
error_route {
xlog("L_INFO","Bad message from $proto:$si:$sp\n$mb\n");
drop();
}

I've found one more feature missed in 3.1 - error_route is eliminated
and sanity module added. But if received SIP message is malformed and
can't be parsed, routing script is not executed and I have no way to
log the message to kamailio log. I did it in error_route before.
This logging is important to me to support customers. SIP ALG in
routers often breaks Via line :-(
Since I developed error_route, I remember that it handled just sporadic
cases, but I can add an event_route to pass the buffer and some hints
to configuration file in case the initial parsing fails and the message
is dropped before getting to config file.
It is good to know that someone use such case, introduction of sanity
was clearly mentioned and so far there was no complain.

seems was lost in transition to 3.0, I will check to see what can be
