# Notes on those who base their configuration on this:
#  1) check security issues! (allowed IPs, passwords and ports)
#  2) groups cannot have empty rows inside them!
#  3) read the user guide

# CORE
#
# There is only one core group and it sets all basic settings
# of the bearerbox (and system). You should take extra notes on
# configuration variables like 'store-file' (or 'store-dir'),
# 'admin-allow-ip' and 'access.log'

# SMSC CONNECTIONS
#
# SMSC connections are created in bearerbox and they handle SMSC specific
# protocol and message relying. You need these to actually receive and send
# messages to handset, but can use GSM modems as virtual SMSCs

# SEND-SMS USERS
#
# These users are used when Kannel smsbox sendsms interface is used to

# This is the username and password that RapidSMS uses to deliver SMSes to
# Kannel.  It must also set the 'smsc' variable in the query string, so that
# Kannel knows which SMSC to use to route the message.

# SERVICES
#
# These are 'responses' to sms PULL messages, i.e. messages arriving from
# handsets. The response is based on message content. Only one sms-service is

# even if RapidSMS is offline for some reason.

# configured SMSCs to the appropriate HTTP backend URLs in RapidSMS.
# By setting 'accepted-smsc', we are assured that messages are routed to
# the appropriate backend in RapidSMS.
