<div>Hi everyone!</div>
<div>&nbsp;</div>
<div>I am probably missing something very&nbsp;basic, but I have problems&nbsp;with simple file record and playback in gsm&nbsp;file&nbsp;format.</div>
<div>&nbsp;</div>
<div>I have just installed 1.0 release system and I changed only default dialplan with following two extensions:</div>
<div>&nbsp;</div>
<div>&lt;extension name=&quot;gsm_record&quot;&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;condition field=&quot;destination_number&quot; expression=&quot;^9991$&quot;&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;action application=&quot;answer&quot;/&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;action application=&quot;record&quot; data=&quot;/tmp/rec.gsm&quot;/&gt;<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/condition&gt;<br>&nbsp;&nbsp;&nbsp; &lt;/extension&gt;</div>
<div>&nbsp;&nbsp;&nbsp; &lt;extension name=&quot;gsm_playback&quot;&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;condition field=&quot;destination_number&quot; expression=&quot;^9992$&quot;&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;action application=&quot;answer&quot;/&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;action application=&quot;playback&quot; data=&quot;/tmp/rec.gsm&quot;/&gt;<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/condition&gt;<br>&nbsp;&nbsp;&nbsp; &lt;/extension&gt;</div>
<div>&nbsp;</div>
<div>
<div>When I place call to&nbsp;9991extension I see INFO message about opening /tmp/rec.gsm, no error messages and when I hangup I can see that file /tmp/rec.gsm exists. However when I try to play this file using 9992 extension the only thing I can hear is noise. </div>

<div>&nbsp;</div>
<div>When I just change name to&nbsp;/tmp/rec.wav in both extensions everything is working fine. </div>
<div>&nbsp;</div></div>
<div>What am&nbsp;I missing?</div>
<div>&nbsp;</div>
<div>Many regards,</div>
