Hi,
I have been quite busy and not been able to pursue this issue further,
however i still haven't resolved this. if somebody has an idea I'd be very
grateful
Thanks for your response Peter, that sounds very likely.

What does this mean? You have something like this?
<action application="lua" data="my_script.lua"/>
[
so my inbound calls come into the dialplan and are sent straight to the
queue without any lua
<condition field="destination_number" expression="^(DDI)">
<action application="answer"/>
<action application="playback"
data="tone_stream://%(400,200,400,450);%(400,2200,400,450)"/>
<action application="sleep" data="1000"/>
<action application="set" data="queuetag=TestQueue"/>
<action application="info"/>
<action application="set" data="fifo_orbit_exten=marc_queue:30/>
<action application="set" data="fifo_orbit_dialplan=XML"/>
<action application="set" data="fifo_orbit_context=default"/>
<action application="set" data="fifo_orbit_announce="/>
<action application="set" data="fifo_caller_exit_key=1"/>
<action application="set" data="fifo_caller_exit_to_orbit=true"/>
<action application="set" data="fifo_override_announce="/>
<action application="fifo" data="queue1 in undef
/usr/local/freeswitch/sounds/moh.wav"/>
then I have a lua script that gets launched on startup and that is an
endless loop that queries the queue1 for any calls in queue.
Once found a call, it queries a database of "available" users to take a
call and sim rings them all until one of them picks up.
local new_session = freeswitch.Session(new_call_string);
<------------------- calling out to the agents.
new_session:execute("set", "call_timeout=9");
new_session:execute("set", "hangup_after_bridge=true");
if ( new_session:ready() ) then
call_state = api:executeString("uuid_exists "..queue1_caller_uuid );
<------ checks that call was still in the queue.
freeswitch.consoleLog("info", "call_state = ".. call_state .. "\n");
if call_state == "true" then
freeswitch.consoleLog("info", "Call Answered by service agent and call
there.\n");
new_session:execute("transfer", "agent_to_queue_marc_queue_service XML
default");
else
new_session:hangup();
new_session:destroy();
end
end
once one of those agents does pick up, the LUA script executes the line
below which transfers the call to another part of the dialplan ( below )
which basically connected the existing call out to the agents to the oldest
call in queue1.
new_session:execute("transfer", "agent_to_queue_marc_queue_service XML
default");
<include>
<extension name="agent_to_queue_marc_queue_service">
<condition field="destination_number"
expression="^(agent_to_queue_marc_queue_service)">
<action application="fifo" data="queue1 out nowait"/>
</condition>
</extension>
</include>
it actually all works very well as far as functionality is concerned, but
the issue is that if I make 100 connected calls, then under the status, the
total number of calls keep incrementing until we hit the max number of
session and then the freeswitch restarts it seems : ( I can increase the
value, but am trying to avoid the issue)
UP 0 years, 6 days, 6 hours, 13 minutes, 33 seconds, 121 milliseconds, 907

What, exactly does your Lua script do? Do you have an explicit exit clause
in there anywhere?
[
so as described above. there is no exit clause as the LUA script is
launched on startup and then constantly polls the queue. if I don;t do a
transfer, the LUA script stays on that command until the call is cleared.
the transfer resolves that issue but creates a stale session.
now it could be that I am looking at this the wrong way. my key requirement
here is that I want to be able to control who the queued call is connected
to based on a number of parameter from an external DB like agents and
distribution mechanism
Anybody got any good ideas? I would have thought it was a relatively common
setup. I could potentially run an individual instance of a LUA script of
each inbound call in the queue and then it would clear automatically when
the bridged call is hung up, but that would potentially mean that I could
be running 100s of identical LUA scripts that last for an unpredictable
length of time.
I'd be very grateful to hear any suggestions
