what is the callflow of the extension you are calling with sipp? start by making the target extension just answer and play back a file till you have it working and expand it from there.
you can comment out the manage-presence option in your sip profile to make the sip a lot less resource intensive. here are the ulimits I set for load testing ulimit -c unlimited ulimit -d unlimited ulimit -f unlimited ulimit -i unlimited ulimit -n 999999 ulimit -q unlimited ulimit -u unlimited ulimit -v unlimited ulimit -x unlimited ulimit -s 244 ulimit -l unlimited On Tue, Jul 8, 2008 at 1:51 PM, Patrick Grondin <[EMAIL PROTECTED]> wrote: > Hi, > > > > I am currently doing some characterization testing to figure out the > limitations of my freeswitch server.
