Hi Brian,
many thanks for your feedback!

Find below some extract from our FS dialplan.
Our SIP system is composed by an Opensips front-end that balances calls on Freeswitch \
hosts. Realtime data and static config are backended on mysql db.


default.xml: a lua script profiling caller / called setting channel_variables.

services.xml:
<include>
  <condition field="${service_type}" expression="IVR" break="on-true">

redir.xml:
<include>
  <context name="redir">
    <!-- On Moved , manage redirection -->
    <extension name="redirections">
      <condition field="destination_number" expression="^(\d+)$">

            <action application="lua" data="functions/call_redirect.lua  ${cCalled} \
${destination_number}"/>  </condition>
    </extension>
  </context>
</include>


call_redirect.lua profile cCalled (forwarder ext) and destination_number (forward \
destination) check session status with session:ready() and execute a bridge with:

app="{ignore_early_media=true,hangup_after_bridge=true,origination_caller_id_name='Da:"..caller.."',originate_timeout=25}sofia/gateway/"..gw[i].."/"..redirected;
 session:execute("bridge", app);

Please note that a-leg is terminated just after b-leg is terminated with \
originator_cancel (sip 487) on SIP moved received from forwarded extensions.

Thanks in advance for you help

Francesco
