Reading event notifications from Grandstream GDS3710

[tigi]

I'm trying to setup event notification for the grandstream GDS3710.
I cannot use an lp script since the gds3710 only accepts an ip and port
   

I've searched the forum for a simple resident script which is able to capture the data the gds3710 sends when an event occurs but without any luck.
I've found a script which at least generates some output but not the whole body.

Code:

* string: POST / HTTP/1.1User-Agent: Wget/1.16.1 (linux-gnu)Accept: */*Accept-Encoding: identityHost: 192.x.x.x:7777Connection: Keep-AliveContent-Type: application/x-www-form-urlencodedContent-Length: 29

Can someone point me to the right direction or alter the script below.

Code:

local socket = require("socket")
local server = assert(socket.bind("*", 7777))
local header
while 1 do
  local client = server:accept()
  local line = client:receive()
  header = line
  while (#line > 0) do
    line = client:receive()
    header = header .. line
  end
  log(header) 
end

Thanks in advance!
