Olle,

	I see.  One of my scenarios uses a bash script to generate calls like so:

if [ ! $1 ]
then
echo "Usage:

$0 account calls delay

"
exit 1
fi

for i in `seq 1 $2`
do
echo "Channel: Local/$1 at call
MaxRetries: 1
RetryTime: 60
WaitTime: 30
Context: loadtest
Extension: $1
Priority: 1" > /tmp/scratch/$i.call && mv \
/tmp/scratch/*.call /tmp/scratch/spool/
sleep $3
done

	I'll find the related Asterisk config portions, but it allows me to 
test the number of calls (with a limit) as well as "calls per second". 
It doesn't have perfect resolution, but it has been accurate enough for 
my tests.

	/tmp/scratch is mounted as tmpfs, and /var/spool/asterisk/outgoing is 
symlinked to "/tmp/scratch/spool".

	I also try to record the audio stream to /tmp/scratch with Monitor or 
Record.  I have been able to get Record to work, but Monitor only writes 
out 160 bytes before stopping (while the RTP continues to flow).  Oh 
well, another issue, another thread.
