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"/[1]>   </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.
