# Show who is calling me.

# It was far too slow using NFS with
# 	tail -f /host/isdn/var/log/isdnd.log | grep -i "call from"
# the answerphone had cut in after 4 rings before it showed who was calling.
# So I've fallen back to running the tail process direct on the gate host.

tail -F /var/log/isdnd.log | grep -i "call from"

# The following commands all hung, so possibly I might hack grep to flush
# a line at a time.
# | cat
# | sed -e s/......................//
# | grep -v "to my_number"
# grep -v is as I want to see only humans, not callers to my data line
