You cannot execute blocking calls on a session that is already doing something from an outside script.

Transfer the uuid to execute the script instead.

uuid_transfer <uuid> lua:script.lua:arg1:arg2:arg3 inline

Or transfer it to park to put it in a passive state.

uuid_transfer <uuid> park inline

Ok, now I understand that getting a session object using uuid can be done as follows:

session = freeswitch.Session(uuid);

However, I am a bit confused.. 

My lua script accepts 3 arguments - uuid, multicast ip & port, and then does the following - create a session using freeswitch, and then execute esf_page_group with the passed multicast and port

What works is:

- Place an incoming call to FIFO queue with an orbit exten and timeout

- In the orbit exten, call lua script with uuid, multicast address and port

After a timeout, it works like a charm - caller can make PA to the listening parties

Now, what doesn't work is:

- Modify lua script to pop out the call from fifo by using execute("fifo","pa_q1 out wait"); and then call esf_page_group

- Place an incoming call to FIFO queue with an orbit exten and large timeout

- Before the timeout occurs, call the lua script from CLI using luarun, pass the required arguments

In this case, the caller is unable to send the stream to multicast address - instead, there seems to be a loopback, caller hears his own audio. I think this is because of the way I am popping out I guess. However, if I don't pop out, the caller seems remain in the queue 

I am just wondering how do I retrieve a call in a fifo queue and play around with it within a lua script?

Hi Brian

Thanks for the reply. My aim is to unpark the call, playback a message to the caller, and then redirect the caller to a multicast paging group(esf_page_group), so that he could do a PA. From what I understand, intercept allows you to bridge to another call, am unsure if my requirement is achievable using this app.

If you have the UUID of the session you wish to unpark why not just execute the intercept app?

Hi,

Is there a way I could create a session using an existing uuid in Lua? I see that this is possible in Javascript, but couldn't get the same to work in Lua.

I am trying to retrieve the session of a parked call, so that I could unpark the same in the lua script (as fifo doesn't seem to work when not in a call context)
