# ----------- global configuration parameters ------------------------
# These are standard parameters for SER
#
# INTERNET HOST AND PORT
#
# The port parameter specifies which TCP/UDP port SER should run. The
# default is 5060 according to RFC 3261.
#
#port=5060
#
# The listen parameter specifies which interface / IP address SER runs.
# By default, SER listens on all interfaces. One can restrict SER to run on
# IP address (e.g. 192.168.1.1), hostname (e.g. sip.some.domain) or
# interface name (e.g. eth0). Multiple entries are accepted by specifying
# more than one. (e.g. listen="eth0" "192.168.1.1" "sip.some.domain")
# Protocol and port number are accepted as well (e.g. tcp:*:5066)
#
listen=eth0

# DEBUG and LOG
#
# The debug parameter specifies the debugging level.
#
#debug=4
#
# The log_facility parameter specifies which syslog facility log message
# is sent to. Default is to send to LOG_DAEMON. See man (8) syslog.conf
# for details
#
log_facility=LOG_LOCAL6
#
# The log_stderr parameter instruct SER to send debugging information
# to stderr instand of syslog. When set to yes and fork is set to no, SER
# will be running in the foreground and messages send to stderr. Default
# is to send to syslog.
#
#log_stderror=no

# DNS related parameters
#check_via=no	# (cmd. line: -v)
#dns=no           # (cmd. line: -r)
#rev_dns=no      # (cmd. line: -R)
#reply_to_via

# SERVER RELATED parameters
#
# The fork parameter, if set to yes, put SER into daemon mode. Otherwise,
# SER will be running in the foreground. Default is yes.
#
#fork=yes
#
# The children parameter specifies how many copies of SER processes should
# be start for each supported protocol and interface. Default is 8 copies
# per interface for both TCP and UDP.
#
children=2
#
sip_warning=no
#server_signature=no
user=ser
group=apache
#chroot="/var/ser"
#wdir="/"
#mhomed=no
#advertised_address="sip.some.domain"
#advertised_port=5060
#syn_branch=no
#disable_core=no
#open_fd_limit=1024

# FIFO related parameters
#
# The fifo_dir parameter specifies the directory where temporary file from
# fifo_reply will be created. This has no relationship to the fifo parameter.
fifo_dir="/tmp/"
#
# The fifo parameter specifies the FIFO file for external program (e.g. serctl)
# to communicat with SER server. Default is /tmp/ser_fifo.
#
fifo="/var/run/ser/ser_fifo"
#
# The fifo_mode parameter specifies the UNIX file mask of the FIFO file.
# Default is the file mask of the running user.
#
fifo_mode=0660
#fifo_db_url=<no idea on this>
avp_db_url="mysql://ser:heslo@localhost/ser"


# UNIX Socket related parameters
unix_sock="/var/run/ser/ser_sock"

# TCP related parameters.
