Hello,<br>
<br>
what should be happen, is the following:<br>
<br>
- invite from controller to first parameter (caller of desired call)<br>
- after 200ok comes from 'caller', kamailio sends REFER to it
pointing to the second parameter (callee of desired call) and then
BYE, getting out of the initial call<br>
- after getting the REFER, caller should send a new INVITE to callee<br>
<br>
You can run with debug=3 to see what happens. In kamailio config is
nothing special needed, just allow traffic from kamailio to go back
to kamailio.<br>
<br>
Cheers,<br>
Daniel<br>
