[Freeswitch-users] Running a session asynchronously from a Lua script

[Adam Wilt]

Hi all,

I want to park an inbound call and play hold music while I simultaneously
place another outbound call.
But the hold music doesn't play while the lua script is placing the second
call. When the lua script ends, the hold music finally starts.
Here's my example code:

#!/usr/local/bin/lua

session:answer()
api = freeswitch.API()
api:executeString("bgapi uuid_park " .. tostring(session.uuid))
api:executeString("bgapi uuid_broadcast " .. tostring(session.uuid) .. "
/freeswitch/sounds/music/8000/danza-espanola-op-37-h-142-xii-arabesca.wav")
local new_session =
freeswitch.Session("sofia/gateway/myprovider/15555555555")


So it seems like the script is blocking the original session, despite the
fact that I'm using bgapi. I'd really appreciate if somebody could help me
with this.

By the way, I'm using FreeSWITCH 1.0.4 in Windows.

Thanks,
Adam

I wouldn't do it like that...

I would let FreeSWITCH do what its good at and stop trying to create and manage sessions manually.

-- You can optionally answer but you need to set transfer_ringback instead of ringback.
session:setVariable("ringback", "local_stream://moh");
session:setVariable("ignore_early_media", "true");
session:execute("bridge","user/1007");

Which can also be expressed in pure XML as such:

<extension name="1234">
<condition field="destination_number" expression="^1234$">
<action application="set" data="ringback=local_stream://moh"/>
<action application="set" data="ignore_early_media=true"/>
<action application="bridge" data="user/1007"/>
</condition>
</extension>

There is really no need to do this with Lua. The XML dialplan can do some VERY complex things once you wrap your head around it.

In addition I would recommend you get the latest 1.0.5 build http://files-sync.freeswitch.org/windows_installer/ Its tagged as 1.0.4 and shouldn't be.

Brian,

Thanks for the reply.
The problem is I don't want the two parties to speak to each other. I want
one party to wait on hold while the system interacts with the other party.
Then the system will hang-up on the second party and start interacting with
the first party again.

Thanks,
Adam

ok the use the api to "originate" the call to say an extension that plays music. But if they never talk to each other what is the point of the two calls in the same script?
