[Freeswitch-users] att_xfer and loopback

[Avi Marcus]

I know you can do anything in the dialstring. But intended feature is to
allow the user to do an attended transfer to any number that they could
reach via the default calling. The default outbound path already has a LOT
of stuff set up and it would be impossible to duplicate that within a
SINGLE dialstring in a function call.
What is needed is for an att_xfer to be able to have leg C hit the dialplan
and bridged however a "normal" leg B to that number would be called.
Does this make sense?
