Hi Bj?rn, I am not sure I understand your problem correctly, but look into Sipek's code and check whether pjsua_call_xfer_replaces is called with PJSUA_XFER_NO_REQUIRE_REPLACES flag. For more info see http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2009-June/007759.html and https://issues.asterisk.org/view.php?id=14350 Vali Bjoern Meier napsal(a): > Hi, > > I'm using the Sipek SDK to write an application for a blinded > co-worker.
