# This example includes a basic configuration for the SmartNode  #
# SN5XXX in combination with two Cisco Call Manager on the LAN     #
# side and a SIP trunk to a VoIP provider on the WAN side.         #
# 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.                                             #
