<div>Hi,</div>
<div>Thank for the quick response.</div>
<div> </div>
<div>The issue occur only when the Alice is a PSTN client.</div>
<div>My ITSP says that they only supporting one call transfer (very strange). They can not explain why etc...</div>
<div> </div>
<div>PSTN client: Alice<br>MGW/MGC(ITSP): Cisco/SER</div>
<div>Our sip server: SIPX</div>

<div class="h5">> Hi,<br>> Have following issue:<br>><br>> Alice calling Bob.<br>> Bob make call transfer to Charlie (works fine)<br>> Charlie transfer Alice to David. (the call break)<br>><br>> Why is not possible to transfer the call more than one time?<br>
> Is it any parameters?<br>><br>> My ITSP use SER together with Cisco MGW.<br><br></div></div>Niklas, nothing in SIP protocol neither in SER/Kamailio makes your<br>scenario to fail. It must be a problem in your custom setup. Try<br>
identifying the problem capturing SIP traces.<br>Also take into account that a proxy doesn't participate at all in the<br>process of a "call transfer". It's just a transparent mechanism for a<br>proxy.<br>
