Did you purchase g.729 licenses for this system? If not then you won't be able to transcode g.729 and the incompatible destination error will keep popping up if you're not in proxy media mode.

Where is the 407 coming from? If it's coming from your provider then they want you to auth calls, which means you need to make sure your gateway has the correct username and password information.

I’m using the external sip profile to route calls from a voice gateway router to an internal PBX.

 

In separate xml files in the sofia/external directory, I have the following:

 

<include>

    <gateway name="Server-1">

      <param name="username" value="gateway"/>

      <param name="password" value="gateway"/>

      <param name="realm" value=" X.X.X.X "/>

      <param name="proxy" value=" X.X.X.X "/>

      <param name="register" value="false"/>

      <param name="context" value="public"/>

    </gateway>

</include>

 

<include>

    <gateway name="Server-2">

      <param name="username" value="gateway"/>

      <param name="password" value="gateway"/>

      <param name="realm" value="X.X.X.X"/>

      <param name="proxy" value="X.X.X.X"/>

      <param name="register" value="false"/>

      <param name="context" value="public"/>

    </gateway>

</include>

 

<include>

    <gateway name="Voice Gateway">

      <param name="username" value="gateway"/>

      <param name="password" value="gateway"/>

      <param name="realm" value="X.X.X.X"/>

      <param name="proxy" value="X.X.X.X"/>

      <param name="register" value="false"/>

      <param name="context" value="public"/>

    </gateway>

</include>

 

In the dial plan/public directory, I have the following (different xml files):

 

<extension name="PBX">

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

       <action application="bridge" data="sofia/gateway/Server-1/$1"/>

       <action application="bridge" data="sofia/gateway/Server-2/$1"/>

   </condition>

</extension>

 

<extension name="PSTN">

   <condition field="destination_number" expression="^(\d{10})$">

       <action application="bridge" data="sofia/gateway/Voice Gateway/$1"/>

   </condition>

</extension>

 

In the sip profiles/eternal.xml file, I have the following major settings:

 

  <settings>

    <param name="inbound-proxy-media" value="false"/>

    <param name="disable-transcoding" value="false"/>

    <param name="inbound-late-negotiation" value="true"/>

    <param name="user-agent-string" value="My Company Name"/>

    <param name="disable-register" value="true"/>

    <param name="inbound-codec-negotiation" value="generous"/>

    <param name="inbound-codec-prefs" value="G729,PCMU"

    <param name="outbound-codec-prefs" value="G729,PCMU"/>

    <param name="media-option" value="resume-media-on-hold"/>

    <param name="stun-enabled" value="false"/>

    <param name="debug" value="0"/>

    <param name="sip-trace" value="no"/>

    <param name="rfc2833-pt" value="101"/>

    <param name="sip-port" value="5080"/>

    <param name="rtp-ip" value="X.X.X.X"/>

    <param name="sip-ip" value="X.X.X.X"/>

    <param name="dialplan" value="XML"/>

    <param name="context" value="public"/>

    <param name="dtmf-duration" value="2000"/>

    <param name="rtp-timer-name" value="soft"/>

    <param name="rtp-timeout-sec" value="300"/>

    <param name="rtp-hold-timeout-sec" value="1800"/>

  </settings>

</profile>

 

Currently, I’m experiencing two issues.

 

1.       Inbound calls work as long as I’m using “inbound-proxy-media”. When I disable that setting and force transcoding, the phone rings but immediately hangs up when I pick up the receiver. I see an “Incompatible Destination” message on the console.

2.       Outbound calls don’t work at all. On the console, I see “407 Proxy Authentication Required”. If I’m using the external profile, how could it require authentication?

 

Any ideas?

 

Thanks,

 

Ken Fulmer
