So right now I'm generating A simple INVITE, let's say from FS-G.

On receiving the INVITE, FS launches a python script which should reject the incoming INVITE from G and start a new call B-leg.

I already do this, but the FS-G leg keeps going and I would like to actually reject and hangup the FS-G leg.

is this possible? Basically hangup the incoming call and keep the script running to create a new leg.
