Jeremy,
"Is it running?" was a very sensible question, especially since I said I was
running from the command line. I'm actually using a second terminal to monitor the
host while the first one is running kamailio in the foreground.
I like to work from the command line until the config is right, then I'll run the
service.
Thanks for the tip on ss, but it also reports nothing listening on 55060 (or 5060).
Without the grep, netstat shows me other processes listening for TCP (on different ports).
Other evidence is that a connection attempt fails.
'disable_tcp=yes' is NOT active. When it is (I checked) Kamailio doesn't
report that it's listening on TCP.
Dave.

obsoleted by ss
Try
netstat -a -n | grep 5060
Also check if your kamialio.cfg file has "disable_tcp=yes" Comment it
out if it does.
P.S. I only asked about whether it was still running because it can
easily die on startup if the scripts detect some error like the control
files still exists. I just checked now on my system which I installed
using 'official' RPMs for Centos 6. The 'service kamailio restart'
command appears to work but fails quietly for the following reason
Apr 12 14:55:40 sentinel /usr/sbin/kamailio[7501]: ERROR: ctl [ctl.c:379]: ERROR: ctl:
could not delete unix socket /tmp/kamailio_ctl: Operation not permitted (1)
