Hi,
thanks for a reply. Command "ngrep -d any -t -W byline port 8448" prints
#####
when CGRateS and telnet connect (TCP handshakes) and stays quiet during the
rest of the test. When I type something into telnet, I can see incoming
packets:
T 2016/08/22 09:18:21.115922 192.168.30.1:46378 -> 192.168.30.29:8448 [AP]
efelin.
Unfortunetely I am no closer to resolving my issue.
Netstat shows:
root at cgrates:/usr/share/cgrates/tutorials/kamevapi/cgrates/etc/init.d#
netstat -tlpnueea | grep kamailio
