I guess it will not work with PSTN lines since the control is transferred to the Exchange. I am not too sure, I am just sharing my thoughts....<br><br><div class="gmail_quote">On Fri, Nov 19, 2010 at 9:28 PM, Giorgio Incantalupo <span dir="ltr">&lt;<a href="mailto:gincantalupo@fgasoftware.com">gincantalupo@fgasoftware.com</a>&gt;</span> wrote:<br>

<br>
I tried it but it seems like my telco is overwriting the value I set as<br>
callerid.<br>
Maybe it is possible with Voip providers only.<br>

&gt;         Subject: [asterisk-users] callerid not forwarded when<br>
&gt;         transferring call from<br>
&gt;         ISDN line to mobile phone via Asterisk<br>
&gt;<br>
&gt;         Hi all,<br>
&gt;<br>
&gt;         I&#39;ve got 4 actors on my stage:<br>
&gt;         Alice calling from outside<br>
&gt;         Bob transferring incoming calls to Charlie<br>
&gt;         Charlie who has a mobile phone<br>
&gt;<br>
&gt;         My PBX which is connected to my ISDN line.<br>
&gt;<br>
&gt;         I want Charlie to see Alice&#39;s Callerid after Bob has<br>
&gt;         transferred the<br>
&gt;         call as if Charlie is receiving the call from  Alice,<br>
&gt;         transparently.<br>
&gt;<br>
&gt;         Tried to set the callerid but Charlie sees my telco line<br>
&gt;         number, not the<br>
&gt;         callerid of Alice.<br>
&gt;<br>
&gt;         How can I do this?<br>
&gt;<br>
&gt;         Thank you.<br>
&gt;<br>
&gt;         Giorgio<br>
&gt;<br>
&gt;<br>
&gt;         --<br>
&gt;         We know that Alice and Charlie are both on external trunks.<br>
&gt;          We DON&#39;T know<br>
&gt;         what flavor of Asterisk you are using, but it probably doesn&#39;t<br>
&gt;         matter your<br>
&gt;         call is going like this<br>
&gt;         ID #1 --&gt; asterisk --&gt; destination.<br>
&gt;         If destination were internal, ID#1 would remain intact, but<br>
&gt;         since you are<br>
&gt;         opening a new trunk to forward the call, you lose ID#2 and<br>
&gt;         replace it with<br>
&gt;         your Telco ID.  You could &quot;spoof&quot; this depending on your asterisk<br>
&gt;         version/telco arrangement, but by default, things are as you<br>
&gt;         described.<br>
