#
# $Id$
#
# This a very basic config file w/ aliases and a named route but
# w/o authentication, accounting, database, multi-domain support etc.
# Please refer to sip-router.cfg for a more complete example
#
# Direct your questions about this file to: <sr-users@lists.kamailio.org>.

# For more information about the various parameters, functions and statements

#------------ Features -----------------------------------------------
# Several extra features can be enabled by adding #!define WITH_<FEATURE>
# statements to the config file, or by starting sr/ser with -A WITH_<FEATURE>.
# E.g.: ser -f /etc/ser/sip-router-basic.cfg -A WITH_TLS

# run in debug mode:
##!define WITH_DEBUG

# enable tls support:
##!define WITH_TLS

# started from compile directory (not installed)
##!define LOCAL_TEST_RUN
