[Freeswitch-dev] accessing key presses with outbound event socket

[Stanislav Sinyagin]

why so complicated?
You can launch a Lua or Javascript script when the user is in the call, collect the needed digits, and then you can do all kinds of database lookup if needed. 

If you really need to use the outbound socket, make sure you use the "full" mode -- then you can collect the digits from your event socket application. In this case, you would only need one port, and you would be able to execute the API call to collect the digits:

Hi all,

I'm still curious if it's possible to query a user in an outbound event
soekct, but in the meantime I came up with a work around.

I've configured the event socket application to listen on ports 50,001 -
50,999.

Then, I prompt for the conference number (between 1 and 999) in the
freeswitch configuration (which is trivial) *before* sending the user to
the event socket application. I add 50,000 to the number and then use
that port number when connecting to the event socket application.

The event socket app simply checks what the incoming port is being used,
subtracts 50,000 and set the conference number accordingly.
