How to connect FreeSwitch to FreeSwitch?

3
votes

i have a problem with FreeSwitch. I tried for hours to connect a FreeSwitch server on my system with a FreeSwitch server on another system. However, what i want is to call with user "abc@myip" the user "123@buddysIp". What i tried is to add a new "list" item to the acl.conf.xml

<list name="buddy" default="deny">
      <node type="allow" cidr="hisip/32"/>
  </list>

also i tried to add an extension in the conf/dialplan/default directory

<include>
<extension name="outbound_calls">
    <condition field="destination_number" expression="^(.*)$">
        <action application="bridge" data="sofia/gateway/buddy/$1"/>
    </condition>
</extension>

and his gateway which is stored in conf/sip_profiles/buddy.xml and looks like this

<include>
<gateway name="buddy">
    <param name="realm" value="hisip"/>
    <param name="username" value="myuser"/>
    <param name="password" value="mypw"/>
</gateway>

I hope somebody can help me. Maybe i forgot something. We are in the same network. Please tell me if you need more informations, thanks.

Here are my call log:

It works know. I created a gateway in sip_profiles/external/mygateway.xml looks like 

<include>
    <gateway name="buddygateway">
        <param name="proxy" value="buddyip"/>
        <param name="register" value="false"/>
        <param name="caller-id-in-from" value="true"/> <!--Most gateways seem to want this-->
    </gateway>
</include>

and created an outbound extension in dialplan/default/outbound_calls.xml looks like this:

<include>
    <extension name="outbound_calls">
        <condition field="destination_number" expression="^BUDDYPREFIX(\d*)$">
            <action application="bridge" data="sofia/gateway/buddygateway/$1"/>
        </condition>
    </extension>
</include>

so every number i call now starts with BUDDYPREFIX calls the number on the remote server.

Thanks for the answers :) Hope this will help somebody.

you can send the call to "external" SIP profile (port 5080), then it won't be authenticated. Then you need the dialplan rules in the public context to process such calls. Alternatively, you can create a new profile and attach it to a different UDP port, or even to a specific Ethernet port by explicitly specifying the bind IP address.

In the piece of log that you provided, it looks like the call is landed on port 51155. Is there a special SIP profile attached to that port? If so, probably you need to disable authentication on that profile.

But in general, you need to order a couple of hours of consultancy, so that a specialist explains you how things work. I can do that if needed too.
