You originate a call with auto answer to the door phone, and have it call an extension which does the fork dial (just calling bridge with originate syntax for fork dial).  There is no conference in play unless you want multiple parties to talk to it at the same time.

Sorry, i try to restate:

Raspberry is running FS, connected are a door SIP and (many) other device in the house. Completely external to the devices and FS an event "bell" is generated (assume by some event on the GPIO). This should trigger FS to connect 1 Leg to the door SIP (which will answer automatically and is always a participant) and the other leg to the first in house phone to answer. The complete session is FS initiated.

So i have two successful "originate" calls and need two connect the two ends together... a kind of "two man conference invitation".

Am i still obscure?
