Emrah, can you please paste the successful dump of call when you transfer from Polycom. I observe strange bahaviour when FS sends BYE to Yealink to shutdown the dialog and Yealink also kills the dialog with it&#39;s BYE.<br>

Hi all,<br>
<br>
I have tried to play with the refer extension and now have my calls land in the public context when they are transferred…<br>
This is the second extension in my dialplan:<br>
&lt;extension name=&quot;refer&quot;&gt;<br>
 &lt;condition field=&quot;${sip_refer_to}&quot;&gt;<br>
        &lt;expression&gt;&lt;![CDATA[&lt;sip:${destination_number}@${domain_name}&gt;]]&gt;&lt;/expression&gt;<br>
 &lt;/condition&gt;<br>
 &lt;condition field=&quot;${sip_refer_to}&quot;&gt;<br>
        &lt;expression&gt;&lt;![CDATA[&lt;sip:(.*)@(.*)&gt;]]&gt;&lt;/expression&gt;<br>
        &lt;action application=&quot;set&quot; data=&quot;refer_user=$1&quot;/&gt;<br>
        &lt;action application=&quot;set&quot; data=&quot;refer_domain=$2&quot;/&gt;<br>
        &lt;action application=&quot;info&quot;/&gt;<br>
        &lt;action application=&quot;bridge&quot; data=&quot;sofia/${use_profile}/${refer_user}@${domain_name}&quot;/&gt;<br>
 &lt;/condition&gt;<br>
    &lt;/extension&gt;<br>
<br>
Any help would be greatly appreciated.<br>
<br>
All the best,<br>
Emrah<br>

&gt; Hi all,<br>
&gt;<br>
&gt; I seem to be encountering the strangest problems.<br>
&gt; I have been doing some more testing with my transfers and here is a recurring issue.<br>
&gt;<br>
&gt; I have 2 phones behind the same router. 1 Polycom VVX 1500 and 1 Yealink SIP-T38g<br>
&gt; They are both registering on the same FS server which is on a remote public IP.<br>
&gt; The Polycom has extension 20 and the yealink uses 21.<br>
&gt; When I call the Polycom from the Yealink and perform a blind transfer from the Yealink, it fails with: 481 Call Leg/Transaction Does Not Exist.<br>
&gt; If I transfer from the Polycom though, it seems to work.<br>
&gt;<br>
&gt; In resume:<br>
&gt; I cannot transfer from A leg. B leg doesn&#39;t seem to know its way around and looses it. To demonstrate, I transfer B leg from A leg to extension 5000.<br>

&gt;<br>
&gt; I tried Googleing the error code and didn&#39;t find anything particularly related to my issue.<br>
&gt;<br>
&gt; Any hint would be greatly appreciated. To make sure, I downgraded to the stable version.<br>
&gt;<br>
&gt; Thanks a bunch, as always.<br>
&gt; Emrah<br>
