The old Linphone 3 sent notifications via Dbus, but apparently that
code was scrapped.

Watching/querying call-history.db won't work because incoming calls
get committed to it only after the call has terminated.

What works somewhat is running Linphone like this and parsing its
output and execute programs based on that:

    stdbuf -o L linphone \
      | grep --line-buffered -e '"Add call:"' \
      | stdbuf -o L cut -d'"' -f6- \
      | sed --unbuffered 's@\(\\"\)\(.*\)\(\\"\).*@\2@' \
      | xargs -d '\n' -n1 printf '%s\n'

You can then call a shellscript from xargs that performs the lookup.
The regex for the sed command may need fine-tuning.

Regards.
