Hello,<br>
<br>
the r-uri in the bad ACK is pointing to the proxy, as I understood
from the headers. It should point to callee IP address.<br>
<br>
Look at he 200ok for INVITE to see the Contact address -- some
device involved in the call does not implement properly loose
routing or the contact address is improperly updated somewhere.<br>
<br>
Cheers,<br>

<div>The background: I'm just trying to implement a simple load
balancer with one source and multiple destinations using the
call load balancer (ALG10) in dispatcher. kamailio version 3.2.0</div>
<div>The symptoms: I have a simple script working in one test
environment (csipsimple -> kamailaio -> Twinkle) but can't
get it to work in another (Dialogic HMP 3.0 -> kamailio ->
Dialogic HMP 3.0)</div>
<div>
The details: I've done a debug trace (below) in both
environments and can't see the problem. For some reason the ACK
is destroyed before it is forwarded even though the log says
"[forward.c:601]: Sending:#012ACK..."</div>
<div><br>
</div>
<div>Any help would be much appreciated!</div>
