I don't recall any change to this part for 4.2 and I am using
dlg_bridge with 4.1 (no time to upgrade that box yet) -- but
apparently there is a bug building the REFER. There were few changes
on how From/To are built locally, but they are ok.<br>
<br>
I am traveling at Astricon, but with first occasion I will check it.<br>
<br>
Cheers,<br>

<div style="word-wrap: break-word; -webkit-nbsp-mode: space;

reply Daniel. I have enabled debug=3 and put in a few more
xlog lines. I can see the REFER coming in on local
interface 127.0.0.1. I am now trying to narrow down the
issue in the kamailio.cfg.
<div><br>
</div>
<div>My conclusions so far are:</div>
<div>1) The REFER packet has a problem which causes it to
fail sanity_check()</div>
<div>2) sanity_check returns 0=exit rather than -1 = error.</div>

<div>I have 2 snom phones registered to the kamailio
server over NAT and can make calls between them.</div>

script stops there. </div>

<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>
