When neitther bypass media nor proxy media is set, FS still is in the media path. The difference between &#39;normal&#39; and &#39;proxy&#39; is that FS doesn&#39;t do anything with the media, just passes it straight through.<br>
<br>You seem to be thinking that bypass media is the default - it isn&#39;t.<br><br>-Steve<br><br><br><br><div class="gmail_quote">On 2 August 2010 09:40, Nyamul Hassan <span dir="ltr">&lt;<a href="mailto:mnhassan@usa.net">mnhassan@usa.net</a>&gt;</span> wrote:<br>

In proxy media mode FS will pass media straight through without any processing. It won&#39;t do any transcoding or any SDP modifcation, so it can&#39;t transcode PCMU &lt;-&gt; G729 and absolute_codec_string will be ignored - it&#39;ll just pass the codec settings straight through from the A leg to the B leg.<br>

        I&#39;m not sure it&#39;s bug or not ?<br>
I try to test codec  negotate. with 3 FS box<br>
FS1 send PCMA to FS2 and FS2 send G729 to FS3<br>
<br>
FS1 -----&gt; [PCMU] ----&gt; FS2 ------&gt; [G729] -------&gt; FS3 (10.20.2.49)<br>
My dialplan<br>
&lt;action application=&quot;bridge&quot;<br>
data=&quot;{absolute_codec_string=&#39;G729&#39;}sofia/internal/<a href="http://2222@10.20.2.49:5080" target="_blank">2222@10.20.2.49:5080</a>&quot;/&gt;<br>
It&#39;s work fine<br>
When i try<br>
&lt;action application=&quot;set&quot; data=&quot;proxy_media=true&quot;/&gt;<br>
&lt;action application=&quot;bridge&quot;<br>
data=&quot;{absolute_codec_string=&#39;G729&#39;}sofia/internal/<a href="http://2222@10.20.2.49:5080" target="_blank">2222@10.20.2.49:5080</a>&quot;/&gt;<br>
Call fail. because FS2 ignore absolute_codec_string=&#39;G729&#39; and send<br>
only  PCMU  (I think by pass from FS1)<br>
<br>
It&#39;s bug or not ?<br>
