Hello Patrick,

then maybe the first place to start would be my 
'/etc/opensips/opensips.cfg', which I've generated with 'osipsconfig' 
and edited just a bit:

#
# $Id$
#
# OpenSIPS residential configuration script
#     by OpenSIPS Solutions <team at opensips-solutions.com>
#
# This script was generated via "make menuconfig", from
#   the "Residential" scenario.
# You can enable / disable more features / functionalities by
#   re-generating the scenario with different options.#
#
# Please refer to the Core CookBook at:
#      http://www.opensips.org/Resources/DocsCookbooks
# for a explanation of possible statements, functions and parameters.
