Until now I only had the case with exosip (e.g. my SIPTAPI) which puts 
in the outbound proxy as pre loaded route (enum.at is hosted by ...160 
but exosip does not support SRV thus I have to use a pre loaded route 
with .160 as next hop, although this is main proxy):

INVITE sip:klaus at enum.at SIP/2.0
Via: SIP/2.0/UDP 10.10.0.50:5088;rport;branch=z9hG4bK662862690
Route: <sip:83.136.32.160;lr>
From: <sip:klaus at enum.at>;tag=3909918647
To: <sip:klaus at enum.at>

So, there is only 1 route header, without totag.

If this message is processed by loose_route, loose_route recognizes that 
.160 is itself and thus the loose_route block is not entered but the 
message is processed like any other request without route header 
(openser 1.0.0)
