Hi Olle,<br>
<br>
I haven't had any time for the last few months to work on
outbound. So there is some module boiler plate and a set of notes
(attached) at the moment and not much more.<br>
<br>
I have a requirement for outbound myself for early next year, so
will be picking it up again soon, but there is little to no chance
of it making it into Kamailio 3.4.<br>
<br>
One thing that would speed up the development of outbound is if
someone else (who knows about the internals of the registrar and
usrloc modules) took on the tasks relating to those. These are
basically:
<ul>
<li>Handle multiple registrations with same instance ID but
difference reg-id (may already be supported) </li>
</ul>
</blockquote>
this should be supported, there is no unique key on instance only
and reg-id is saved -- in the worst case, the required changes are
very small.<br>
<br>
<blockquote

type="cite">
<ul>
<li>Have registrar populate an AVP array (specified as a
modparam), ordered by reg-id, when a lookup() is performed -
similar to dispatcher (but don't break parallel and serial
forking) - set $du to first contact in the AVP array. </li>
</ul>
</blockquote>
<br>
This one can be also easily added, we have t_load_contacts() which
serializes the contact records based on Q value. It has to be
extended to work on reg-id:<br>

<ul>
<li>New API (lookup_next_dest()) in registrar that allow you to
work through the set in order if a 430 is returned (API needs
to remove failed contacts from the location table) - again,
similar to dispatcher
</li>
</ul>
</blockquote>
<br>
There is t_next_contacts(), working on the set of avps built by
t_load_contacts() -- again, it need some enhancements, but probably
not hard work.<br>
<br>
Perhaps I can help on the above points, even do them myself, but I
can't give any timelines for the moment.<br>
<br>

And for being able to use outbound for NAT traversal on a single
server (so no Edge proxies):
<ul>
<li>Make registrar able to detect that the top Path-URI for the
contact is actually an interface on the local server, and if
it has an ;ob parameter and a flow token, set $du based on
that.
</li>
</ul>
</blockquote>
<br>
Address in firth path will be used to set $du anyhow, not sure what
the flow token implies, but might be just done from config.<br>
<br>
Cheers,<br>

This would allow me to focus on the Edge server behaviour, which
involves changes to path, rr, a new outbound module, and some
configuration examples (for edge and proxy/registrar).<br>

<pre>Peter,
What's the current status of the outbound support? Which branch is it?
Can we do anything to help to get this into the coming release?
