[Freeswitch-users] Setting Up an Sip Trunk without Authentication

[Dave]

Yes, I am only testing inbound.  When I call from our office phone (not connected to FreeSWITCH, it's on a trunk from broadvox)  I Get a busy signal and at that moment FreeSWITCH shows...
"SIP auth challenge (INVITE) on sofia profile 'internal' for [myphone at theirIP] from their IP.

If I call from my cell phone I get the Operator Message "your call did not go through" and at that moment the same thing shows in FreeSWITCH
"SIP auth challenge (INVITE) on sofia profile 'internal' for [myphone at theirIP] from their IP.

    Under "domains" in acl.conf.xml I added  

       <node type="allow" value="xxx.xxx.xxx.xxx"/>

  The correct syntax is:
  <node type="allow" cidr="xxx.xxx.xxx.xxx/32"/>

    x's are the IP address it's just a single address not a CIDR.


    And I created the file velocity_did.xml with the following code..

    <include>
      <extension name="velocity_did">

        <condition field="destination_number" expression="^(2064001950)$">

          <action application="set" data="domain_name=$${domain}"/>
          <action application="answer"/>

       <action application="lua" data="cme_ivr.lua channel_name"/>
     
     </condition>
      </extension>

    </include>

    I still just get the "SIP auth challenge (INVITE) on sofia profile 'internal' for [myphone at theirIP] from their IP, but nothing more.

  Wait - can you explain *exactly* what you're doing for testing? Are you trying to dial out via Velocity and back in to your DID? If so then you have 2 completely different things you need to set up. The instructions I gave were only for inbound DID, so use a cell phone or something to test that.


  For outbound it seems like they are sending you an auth challenge, which means they need to give you a username and password as well as a host/ip. You need to create a gateway, preferably in your external profile. Just be sure to set the "register" param to false since they are not expecting you to register with them.

    Do I need to change the line ..

    <action application="set" data="domain_name=$${domain}"/>

    to the IP address? If so what syntax?

    They have no Domain Name.

    Thanks again for your help.

      Dave, 


      If you are simply handling incoming calls then you will need to do two things:


      Add Velocity's IP addr to the domains section of acl.conf.xml
      Add an extension to the public context (conf/dialplan/public.xml)


      Allowing a call into FS via an ACL will send it into the "public" context; from there you need to transfer it to the default context or just send it straight to your Lua script.


      Also, I don't believe you need to use a "bridge" app based on the description you gave. Bridge is used to create a new outbound call leg (B leg) and connect it to the inbound call leg (A leg). If you just are handling a call with an IVR then there is no B leg needed, thus no need to bridge.


      Welcome to FreeSWITCH, btw! :) I can highly recommend the FS book (the "bridge" book, ironically) as it discusses some of these basic concepts that will make your FS experience a whole lot more pleasant.

        Hi,

        I am new to FreeSWITCH and need to set up FreeSWITCH to receive calls through a Velocity Networks SIP trunk. They say I should not authenticate with Username and Password. Rather, I connect directly to the their IP address.

        I put

        <extension name="velocity">
              <condition field="destination_number" expression="^2064001950$">
                <action application="bridge" data="sofia/external/$ {destination_number}@their_ip_address"/>
                <action application="lua" data="cme_ivr.lua channel_name"/>
             </condition>
        </extension>

        in the default.xml under Dialplan

        When I Dial the DID from a Phone (not one connected to the FreeSWITCH server) I get the "SIP auth challenge (INVITE) on sofia profile 'internal' for [myphone at theirIP] from their IP, but nothing more.

        What I hope to do is take the incoming call from 2064001950 and route it to the Lua IVR script above.

        I Appreciate any help you may offer.

        Dave Goodwin
