[Freeswitch-users] Follow me implementation

Also forgot to add, I'd have to use Loopback because I would have to send
the follow me number back through the dialplan in order to figure out which
gateway it should go out (we select a gateway based on a few different
variables, but there's no way to tell until you send it through the
dialplan). I know Loopback is kinda evil but I don't see another way of
doing it. But theoretically it makes things a little more modular and
keeps maintenance of the dialplan to a minimum.

Thank you,
