If so, how? kamailio cannot bridge a call like freeswitch does, because kamailio doesn't handle media stream. The only option that you can do in kamailio to connect two phones is to rely on REFER for doing a call transfer. See dialog module and dlg bridge feature from there, maybe it is enough for what you want to achieve.
