It might be really handy to be able to specify the trunk to flash() as
an argument. I use flash in my dialplan to transfer incoming calls to my
cell phone when I'm out and about - frees up the line and reduces
attenuation caused by an analog trombone. It'd be handy to be able to
use it to transfer terminated calls as well.
