Hello,

if my SIP client tries to connect ... a server error occured (see below). Could you please help me to figure out the reason?
Kamailio is installed on an amazon instance with an elastic IP (52.208.249.214, hostname: synth.ddns.net).

Thanks
Hermann

2) My logfile /var/log/kamailio/kamailio.log is empty though

/etc/rsyslog.d/kamailio.conf exists with the entry:

local0.* -/var/log/kamailio/kamailio.log

And in /etc/kamailio/kamailio.conf:
log_facility=LOG_LOCAL0

Why is the logfile empty?

Thanks Herman
