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

[Răzvan Crainea]

Hi, Xi!

In order to use the MI fifo, you should first take a look at the module 
documentation[1]. You have there an example[2] of how a request should 
be built, and also the syntax grammar[3].
Just out of curiosity, why don't you use directly the opensipsctl tool?
