Hello @christoph-v
Below log is from S-CSCF. For some reason S-CSCF is forwarding the packets to
HSS(hss.net1.test:5065) and not to AS. When I run netcat(nc -vv -u -l 5065) on
HSS, I am able to see SIP packets.
Not sure why ims_isc module is sending the packets to HSS. HSS host name is
present only on Bind configuration and scscf.xml file. So I am assuming that
S-CSCF is picking <Defaultroute> parameter from scscf.xml.
