[Freeswitch-users] screen pop with freeswitch？

[Saugort Dario Garcia Tovar]

Hi,

I am playing with freeswitch scripting with lua. I want call to number,
ex 1000, a script lua will process the call ( as an IVR), then transfer
the call to an extension (or transfer the call to a queue, to get a free
agent).
Questions:
How I add a pair data (key/value. ex ID/1234) to the call in the lua
script?
How can check the data attached is avaliable to the end extension?
What you use to make screen pop call data when the call ring in the
extension?

Thanks
