I know a company that based on db_flatstore, they have a module that
instead of writing the db records to a local file, they are pushed
via network to other applications.<br>
<br>
The second approach is better for our project point of view, it is a
feature I would like to see in trunk -- this has the advantage of
being able to use kamailio to receive the duplicates. But overall
both are ok, so finally it is up to what is more convenient for you.<br>

<p class="MsoNormal">Hello,<br>
<br>
probably it was forgotten to export the internal API bind
function. I just committed the fix on GIT master branch (devel
version):<br>
<br>
<a moz-do-not-send="true"
href="http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=db188fbcf4d752a2afab2e298a2f081f836d7e92">http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=db188fbcf4d752a2afab2e298a2f081f836d7e92</a><br>
<br>
I couldn't test it for now, so if you can give it a try and
report whether it is working ok or not, then I can backport
the fix to 3.1.<br>
<br>
Thanks,<br>
