# This example includes a basic configuration for the SmartNode  #
# 49XX/ISDN in combination with a Cisco Call Manager with        #
# authentication and registration                                #
# This example can be used for other SmartNodes too. The only    #
# thing which needs to be adjusted, are the ports and interfaces #
# as far as required.                                            #
