<div class="moz-cite-prefix">When user is registered everything is

not that smart. Found the place in code which detects an outgoing

<br>
Have a problem with a multihomed proxy which doesn't select
outgoing <br>
interface correctly. Found similar topics where people
discussed usage <br>
of force_send_socket() when they want to force opensips to
use some <br>
interface.<br>
<br>
As far as I understood "mhomed=1" is the option which forces
opensips to <br>
select a proper outgoing interface in multihomed
environment. This <br>
options really works, but unfortunately only for UDP. When
opensips has <br>
multiple TCP / TLS / BIN interfaces, opensips just takes the
first from <br>
the list which is not always correct and fails to establish
an outgoing <br>
connection.<br>
<br>
Since I have a module that detects an outgoing interface I
can use this <br>
info with $fs to force correct socket for SIP. Unfortunately
this trick <br>
doesn't work for BIN and it's not possible to setup a
multihomed <br>
opensips with clustering neighbors in both internal and
external networks.<br>
<br>
Is there any workaround for BIN?<br>
