# Network configuration

# optional parameter: media_ip=<ip_address>|<device>
# 
# - this informs SEMS about the IP address or interface that 
#   SEMS uses to send and receive media.  If not set, defaults 
#   to first non-loopback interface.
#
# Examples: 
#  media_ip=10.0.0.34
#  media_ip=eth0

# optional parameter: sip_ip=<ip_address>
#
# - this informs SEMS about the SIP IP where its SIP stack is 
#   bound to or should be bound to. This also sets 
#   the value used for contact header in outgoing calls and 
#   registrations. If not set, defaults to first non-loopback
#   interface.
#
# Example:
#  sip_ip=10.0.0.34
#

# optional parameter: public_ip=<ip_address>
# 
# - when running SEMS behind certain simple NAT configurations,
#   you can use this parameter to inform SEMS of its public IP
#   address. If this parameter is set, SEMS will write this value
#   into SDP bodies.
#   If this parameter is not set, the local IP address is used.
#   N.B., there is no support for port translation; the local 
#   RTP port is advertised in SDP in either case.
#   
# Example:
#  public_ip=75.101.219.48
#  
  
# optional parameter: sip_port=<port_number>
#
# - this informs SEMS about the port where its SIP stack is 
#   bound to or should be bound to. SEMS needs this information
#   to correctly set the contact header in outgoing calls 
#   and registrations. Should be set to equal the 'port' 
#   configuration option in ser_sems.cfg.
#  
#   default: 5060
#
sip_port=5080

# optional parameter: outbound_proxy=uri
#
# - this sets an outbound proxy for calls and registrations initiated 
#   by SEMS. This does not apply to requests in a dialog that 
#   is initiated by someone else and incoming to SEMS.
#   If this is not set (default setting), then for dialogs 
#   initiated by SEMS the r-uri is resolved and the request 
#   is sent there directly.
#   This is resolved by the SIP stack with DNS if a name is given.
#   Warning: If the value set here can not be resolved, no 
#            requests will be sent out at all!
#  
#   default: empty
#
# Example:
#   outbound_proxy=sip:proxy.mydomain.net

# optional parameter: force_outbound_proxy={yes|no}
#
# - forces SEMS to send any request to the outbound proxy in any
#   situation. This option will only have an effect if the 
#   outbound_proxy option has been set.
#
#   default: no
#
# Example:
#   force_outbound_proxy=yes

# optional parameter: rtp_low_port=<port>
#
# - sets lowest for RTP used port
rtp_low_port=10000

# optional parameter: rtp_high_port=<port>
#
# - sets highest for RTP used port 
rtp_high_port=60000

# Additional IFs (optional): 
#   additional_interface = <list of interfaces>
#
# For each additional interface, a set of parameters
# suffixed with the interface name should be defined.
#
# Please note that for each additional interface,
# 'sip_ip' is mandatory. The other
# parameters are optional.
# 
# Example:
#  additional_interfaces=intern,extern
#  
#  sip_ip_intern=192.168.0.5
#  sip_port_intern=5060
#  media_ip_intern=192.168.10.5
#  rtp_low_port_intern=2000
#  rtp_high_port_intern=5000
#
#  sip_ip_extern=213.192.59.73
#  sip_port_extern=5060
#  media_ip_extern=213.192.59.73
#  rtp_low_port_extern=2000
#  rtp_high_port_extern=5000
#  public_ip_extern=213.192.35.73

# modules and application configuration
#
# Configuration of plugin (module) loading:
# - if load_plugins is set, only those are loaded.

#   directory are loaded, except those which are listed 
#   in exclude_plugins.
#

# optional parameter: plugin_path=<path>
# 
# - sets the path to the plug-ins' binaries
# - may be absolute or relative to CWD
plugin_path=${SEMS_EXEC_PREFIX}/${SEMS_LIBDIR}/sems/plug-in/

# optional parameter: load_plugins=<modules list>
# 
# semicolon-separated list of modules to load.

# optional parameter: application
# 
# This controls which application is to be executed if there 
# is no explicit application requested from the SIP stack 
# (i.e. unixsockctrl and second parameter of t_write_unix).
#
# This can be one of 
#    $(ruri.user)       - user part of ruri is taken as application,
#                         e.g. sip:announcement@host
#    $(ruri.param)      - uri parameter "app", e.g. 
#                         sip:joe@host.net;app=announcement
#    $(apphdr)          - the value of the P-App-Name header is used
#
#    $(mapping)         - regex=>application mapping is read from
#                         app_mapping.conf (see app_mapping.conf)
#    <application name> - application name configured here, e.g.
#                         application=announcement

# application = $(ruri.user)
# application = $(ruri.param)

plugin_config_path=${SEMS_CFG_PREFIX}/etc/sems/etc/

# optional parameter: exclude_payloads=<payload list>
#
# semicolon-separated list of payloads to exclude from loading
# ('blacklist'). 
# 
# For example, to only use low bandwidth codecs:
#  exclude_payloads=PCMU;PCMA;G726-40;G726-32;G721;L16
# or, to use only codecs which are not CPU-intensive:
#  exclude_payloads=iLBC;speex;
# only use G711 (exclude everything else):
#  exclude_payloads=iLBC;speex;G726-40;G726-32;G721;G726-24;G726-16;GSM;L16

# tuning

# optional parameter: session_processor_threads=<num_value>
#

#   Defaults to 10
#
# session_processor_threads=50

# optional parameter: media_processor_threads=<num_value>

# Example:
#  session_limit="1000;503;Server overload"

# optional parameter: options_session_limit=<limit>;<err code>;<err reason>

#
# codec_order=iLBC,GSM

# optional parameter: ignore_rtpxheaders={yes|no}

# default: internal
#
# dtmf_detector=spandsp

# optional parameter: unhandled_reply_loglevel={error|warn|info|debug|no}
# 
# the default application logic implemented in the applications is to stop 
# the session right after sending BYE, without waiting for a reply. this
