# This file allows you to alter the configuration of the Asterisk
# init.d script. Normally you should leave the file as-is.
#
# RUNASTERISK: If set to anything other that 'yes', the asterisk init.d script
#              will not run. The default is 'yes'.
#RUNASTERISK=no
#
#
# AST_REALTIME: if set to anything other than "no", asterisk will run in 
#               real-time priority (pass '-p' to asterisk). un-rem the 
#               following line to disable asterisk from running in real-time 
#               priority. The default is 'yes'.
#AST_REALTIME=no
#
# PARAMS: extra parameters to pass to asterisk: generate cores in 
#         case of crash, and be more verbose. -F guarantees that Asterisk 
#         will still run daemonized.
#
#         Instead of adding switches here, consider editing 
#         /etc/asterisk/asterisk.conf
