If you have to reason to go through Kamailio for this, you can simply 
trigger the command from any other external application. There's a 
sample script included in the repo that can be used for this purpose 
directly (making use of the Perl module that is also included): 

There's also a nodejs client that I'm aware of: 

Or you can hand-roll the request and talk to rtpengine via HTTP or 
Websocket for example.
