Hey everyone,

Following a very interesting but old and un-answered post here: http://www.voipuser.org/forum_topic_6616.html
about the integration of Click-To-Call web applications with OpenSER I wanted to give it a try
myself through the FIFO interface.

Before jumping into scripts and code I was wondering if someone can make
it clear how to use those fifo commands that "initiate" a call between 2 parties,
from that post, the user uses:

/* construct FIFO command */
$fifo_cmd=":t_uac:".$myfilename."\n".
    "REFER\n".$caller."\n".
    "p-version: ".$signature."\n".
    "Contact: ".$web_contact."\n".
    "Referred-By: ".$web_contact."\n".
   "Refer-To: ".$callee."\n".
    "\n". /* EoHeader */
    ".\n\n"; /* EoFifoRequest */

Is there documentation available on the various fifo commands like this that I can use?
Can I simply echo the fifo command string to /tmp/openser_fifo?


Thanks in advance,
Regards,
Liran.
