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.
