I'm trying to build a Freeswitch / Raspberry based door communication. While there are some examples for such a constellation for Asterisk, i didn't find (and was not able to invent myself so far) a Freeswitch example. 

The target scenario:

* A SIP based door module, 

* 1-n Pushbuttons, one for each floor

* 1-n SIP Phones per floor

When a push button is pressed i want to initiate a call to the door (that will be accepted automatically) and a call to all phones on the floor. The first one to answer gets connected to the door.

Is this something i can do with "originate" ?
