[OpenSIPS-Users] Any official instructions how to use the MI commands?

[Xi Liu]

I found the instructions on the site of kamailio, and here it is
http://www.kamailio.org/dokuwiki/doku.php/utils:fifo-relay#fifo_commands

So that answered my Question 1, still need help on Question 2. 

Also, I see a lot of reference goes to this file which I assume is the original documentation of OpenSER, but the link is dead. Any one still have a copy of it?
iptel.org/~ janakj/fifo.pdf
