Thank you for your answer!
When I apply your config with small differences (with my domains, without DoS Protection module and with TLS) and have SIGSEGV server crash.

I try to debug this issue the next few days.

Anton

Hi Anton,

saw your email to me directly today. Due to working time i am unable to respond.

Here my successful test flexsip.conf file. I work in AJPbiz.com, so you will see word "AJP" in the file, means i uses those section. Hope is helpful to the rest.

# -1 then no max size
# Default value: 0

# Log (on a different log domain) user errors like authentication,
# registration, routing, etc...
# Default value: false
user-errors-logs=true

# Generate a corefile when crashing. Note that by default linux
# will generate coredumps in '/' which is not so convenient. The
# following shell command can be added to /etc/rc.local in order
# to write core dumps a in specific directory, for example /home/cores:
#       echo "/home/cores/core.%e.%t.%p" >/proc/sys/kernel/core_pattern
# Default value: true
dump-corefiles=true

# Automatically respawn flexisip in case of abnormal termination
# (crashes)
# Default value: true
auto-respawn=true

# List of white space separated host names pointing to this machine.
# This is to prevent loops while routing SIP messages.
# Default value: localhost
aliases=localhost

# Servers started by default when no --server option is specified
# on command line. Possible values are 'proxy', 'presence', separated
# by whitespaces.
# Default value: proxy
default-servers=proxy

# List of white space separated SIP uris where the proxy must listen.
# Wildcard (*) can be used to mean 'all local ip addresses'. If
# 'transport' prameter is unspecified, it will listen to both udp
# and tcp. A local address to bind onto can be indicated in the
# 'maddr' parameter, while the domain part of the uris are used
# as public domain or ip address.
# The 'sips' transport definitions accept two optional parameters:
#       - 'tls-certificates-dir' taking for value a path, with the same
# meaning as the 'tls-certificates-dir' property of this section
# and overriding it for this given transport.
#       - 'tls-verify-incoming' taking for value '0' or '1', to indicate
# whether clients connecting are required to present a valid client
# certificate. Default value is 0.
#       - 'tls-verify-outgoing' taking for value '0' or '1', whether
# flexisip should check the peer certificate when it make an outgoing
# TLS connection to another server. Default value is 1.
#       - 'require-peer-certificate' (deprecated) same as tls-verify-incoming
# Specifying a sip uri with transport=tls is not allowed: the 'sips'
# scheme must be used. As requested by SIP RFC, IPv6 address must
# be enclosed within brakets.
# Here are some examples to understand:
# - listen on all local interfaces for udp and tcp, on standard
# port:
#       transports=sip:*
# - listen on all local interfaces for udp,tcp and tls, on standard

# udp, tcp and tls

# - listen on tls localhost with 2 different ports and SSL certificates:
#       transports=sips:localhost:5061;tls-certificates-dir=path_a sips:localhost:5062;tls-certificates-dir=path_b
# - listen on tls localhost with 2 peer certificate requirements:
#       transports=sips:localhost:5061;tls-verify-incoming=0 sips:localhost:5062;tls-verify-incoming=1
# - listen on 192.168.0.29:6060 with tls, but public hostname is

## The MediaRelay module masquerades SDP message so that all RTP

## The purpose of the Transcoder module is to transparently transcode
## from one audio codec to another to make the communication possible
## between clients that do not share the same set of supported codecs.
## Concretely it adds all missing codecs into the INVITEs it receives,
## and adds codecs matching the original INVITE into the 200Ok. Rtp
## ports and addresses are masqueraded so that the streams can be
## processed by the proxy. The transcoding job is done in the background
## by the mediastreamer2 library, as consequence the set of supported
## codecs is exactly the the same as the codec set supported by mediastreamer2,
## including the possible plugins you may installed to extend mediastreamer2.
## WARNING: this module can conflict with the MediaRelay module as
## both are changin the SDP. Make sure to configure them with different
## to-domains or from-domains filter if you want to enable both of
## them.

## Inter domain connections is a set of feature allowing to dynamically
## connect several flexisip servers together in order to manage SIP
## routing at local and global scope. Let's suppose you have two
## SIP network a.example.net and b.example.net run privately and
## independently (no one from a.example.net needs to call someone
## at b.example.net). However, when people from a and b are outside
## of their network, they register to a worldwide available flexisip
## instance running on 'global.example.net'. It is then possible
## to:
## * have calls made within a.example.net routed locally and sent
## to global.example.net in order to reach users inside and outside
## of a's network. Example: address@hidden calls address@hidden.
## If 2 is registered on a.example.net then the call is routed locally.
## On the contrary if 2 is absent and registered, the call is then
## sent to global.example.net and then routed by the global proxy.
## * when global.example.net receives a call from a user not within
## its native network (ex: address@hidden calls address@hidden),
## it can route this call to the proxy that is responsible for managing
## the local domain (a.example.net).
## This system is dynamic, that is the physical IP address of a and
## b network can change (dynamic ip address)
## .This scenario is achieved with two key features:
## * a.example.net sends a REGISTER to global.example.net to indicate
## that it is the responsible for the entire domain a.example.net.
## The global.example.net authenticates this REGISTER thanks to TLS
## client certificate presented by a.example.net.
## * global.example.net is configured to accept this domain registration
## and route all calls it receives directly and estinated to a.example.net
## domain through the connection established by a.example.net during
## the domain registration.

Hi,
We need to deploy flexisip using external freeswitch based registrar.
What modules and parameters should we use to implement this?
Can someone help with a links to similar solutions?
