Hello world,

I have two freeswitch servers that I want to interconnect. Each one of them has their own sip domain and we want to enable sip communications between them. All the PC can ping together.

Client #1 ------- Freeswitch #1 --(gateway)--- Freeswitch #2 ------ Client# 2.

We have configured a sip gateway on Freeswitch #1 server with the configuration below:

C:\Program Files\FreeSWITCH\conf\sip_profiles\external\gw.xml

<include>
  <gateway name="gw">                                              
  <param name="username" value="3000"/>
  <param name="realm" value="192.168.2.10"/>
  <param name="from-domain" value="192.168.2.10"/>
  <param name="password" value="2009"/>
  <param name="expire-seconds" value="3600"/>
  <param name="register-transport" value="udp"/>
  <param name="retry-seconds" value="30"/>
  <param name="ping" value="25"/>
  </gateway>
</include>

C:\Program Files\FreeSWITCH\conf\dialplan\default\01_example.com.xml

<include>

<extension name="gw">
  <!--<condition field="${toll_allow}" expression="gw"/>  -->
  <condition field="destination_number" expression="^(30[0-2][0-9])$">
    <action application="bridge" data="sofia/gateway/gw/$1@192.168.2.10"/>
  </condition>
</extension>

</include>

In the Freeswitch #2 server, we have configured the 3000 extension:

C:\Program Files\FreeSWITCH\conf\directory\default\3000.xml

<include>
  <user id="3000" mailbox="3000">
    <params>
      <param name="password" value="1234"/>
      <param name="vm-password" value="1000"/>
    </params>
    <variables>
      <variable name="toll_allow" value="domestic,international,local"/>
      <variable name="accountcode" value="3000"/>
      <variable name="user_context" value="default"/>
      <variable name="effective_caller_id_name" value="Extension 3000"/>
      <variable name="effective_caller_id_number" value="3000"/>
      <variable name="outbound_caller_id_name" value="$${outbound_caller_name}"/>
      <variable name="outbound_caller_id_number" value="$${outbound_caller_id}"/>
      <variable name="callgroup" value="techsupport"/>
    </variables>
  </user>
</include>

We have our gateway working.

>>sofia status gateway gw

But we can't do a call between client#1 and client#2.

With Wireshark, we have seen two sip error frame : "407 Proxy authentication required" and "502 bad gateway".

What I must do to make calls between the two sip domains ?

Best regards.
